if((a == 'y'|| a== 'Y')) //use if to check char value
System.out.println("Student accepted in college");//print message
else//defining else block
System.out.println("Student is not accepted in college because he/she not resident of New Jersey ");//print message
}
else//defining else block
System.out.println("Student is not accepted in college because annual income is less than $60000 ");//print message
}
else//defining else block
System.out.println("Student is not accepted in college because GPA is less than 3.75 ");//print message
}
}

The Payroll Department keeps a list of employee information for each pay period in a text file. The format of each line of the file is the following: Write a program that inputs a filename from the user and prints to the terminal a report of the wages paid to the employees for the given period. The report should be in tabular format with the appropriate header.
Answers
Answer:
import pandas as pd
filename = input("Enter file name with the extension included: ")
data = {}
with open("filename", "r") as file:
content = file.readlines()
for line in content:
line_list = line.strip().split(" ")
data[line_list[0]] = line_list[1] * line_list[2]
del line_list
report = pd.DataFrame(list(data.items()), columns = ["lastname", "wages paid"])
print(report)
Explanation:
The python module prompts the user for the file name and opens the text file to extract the employee data with the python open function. It iterates over the file content and saves the last name and the wages paid to the employees ( the hours worked multiplied by the hourly rate) in the dictionary "data".
The dictionary is converted to a dataframe with the Pandas python package and displays the data in tabular format on the screen.
Following are the required code to make a report in tabular format by using the appropriate headers:
Python code:file_name = input('Enter input filename: ')#defining a variable file_name that inputs file value
try:#defining try block that uses thr open method to open file
file = open(file_name, 'r')#defining file variable that opens file
except:#defining exception block when file not found
print('Error opening file ' , file_name)#print message
exit()#calling exit method to close program
print('{:<12s} {:>10s} {:>10s}'.format('Name', 'Hours', 'Total Pay'))#using print method to print headers
for l in file.readlines():#defining loop that holds file value and calculate the value
name, hour, wages = l.split()#defining variable that holds the value of file
hour = int(hour)#holiding hour value
wages = float(wages)#holiding wages value
total = hour * wages#defining variable total variable that calculates the total value
print('{:<12s} {:>10d} {:>10.2f}'.format(name, hour, total))#print calculated value with message
file.close()#close file
Required file (data.txt) with the value:
Database 34 99
base 30 90
case 34 99
Program Explanation:
Defining the variable "file_name" that uses the input method to input the file name with an extension.Using the exception handling to check the file, with using the try block and except block.In the try block check file, and in except block print message with the exit method when file not found.In the next line, a print method has used that prints the header and uses a loop to read the file value.Inside the loop, a header variable is used that splits and holds the file value, calculates the value, prints its value with the message, and closes the file.Output:

Answer:
Split view.
Explanation:
HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.
Generally, all HTML documents are divided into two (2) main parts; body and head. The head contains information such as version of HTML, title of a page, metadata, link to custom favicons and CSS etc. The body of the HTML document contains the contents or informations of a web page to be displayed.
Split view allows the user to see the source code and the visual representation simultaneously.
It can be used in graphic design software such as Adobe Dreamweaver to get a side-by-side view of both the source code and code layout modules or design and source code.
For example, a user with a dual screen monitor can use the split view feature to display the design on monitor while using the other to display the source code.

Explanation:
Type (dog, cat, budgie, lizard, horse, etc.) Create a class that keeps track of the attributes above for pet records at the animal clinic. Decide what instance variables are needed and their data types. Make sure you use int, double, and String data types. Make the instance variables private. Write 2 constructors, one with no parameters and one with many parameters to initialize all the instance variables. Write accessor (get) methods for each of the instance variables. Write mutator (set) methods for each of the instance variables. In the main method of the Animal Clinic class, create 3 Pet objects by calling their constructors. Then call the accessor methods, mutator methods and toString() methods to test all of your methods.
Answers
Answer:
If you did the exercise with two Dog objects, it was a bit boring, right? After all, we have nothing to separate the dogs from each other and no way of knowing, without looking at the source code, which dog produced which bark.
In the previous article, I mentioned that when you create objects, you call a special method called a constructor. The constructor looks like the class name written as a method. For example, for a Dog class, the constructor would be called Dog().
The special thing about constructors is that they are the path to any new object, so they are a great place to call code that initializes an object with default values. Further, the return value from a constructor method is always an object of the class itself, which is why we can assign the return value of the constructor to a variable of the type of class we create.
However, so far, we have not actually created a constructor at all, so how come we can still call that method?
In many languages, C# included, the language gives you a free and empty constructor without you having to do anything. It is implied that you want a constructor; otherwise there would be no way of using the class for anything, so the languages just assume that you have written one.
This invisible and free constructor is called the default constructor, and, in our example, it will look like this:
public Dog(){ }
Notice that this syntax is very similar to the Speak() method we created earlier, except that we do not explicitly return a value nor do we even declare the return type of the method. As I mentioned earlier, a constructor always returns an instance of the class to which it belongs.
In this case, that is the class Dog, and that is why when we write Dog myDog = new Dog(), we can assign the new object to a variable named myDog which is of type Dog.
So let’s add the default constructor to our Dog class. You can either copy the line above or, in Visual Studio, you can use a shortcut: type ctor and hit Tab twice. It should generate the default constructor for you.
The default constructor doesn’t actually give us anything new because it is now explicitly doing what was done implicitly before. However, it is a method, so we can now add content inside the brackets that will execute whenever we call this constructor. And because the constructor runs as the very first thing in an object’s construction, it is a perfect place to add initialization code.
For example, we could set the Name property of our objects to something by adding code such as this:
public Dog()
{
this.Name = "Snoopy";
}
This example will set the Name property of any new objects to “Snoopy”.
Of course, that’s not very useful because not all dogs are called “Snoopy”, so instead, let us change the method signature of the constructor so that it accepts a parameter.
The parentheses of methods aren’t just there to look pretty; they serve to contain parameters that we can use to pass values to a method. This function applies to all methods, not just constructors, but let’s do it for a constructor first.
Change the default constructor signature to this:
public Dog(string dogName)
This addition allows us to send a string parameter into the constructor, and that when we do, we can refer to that parameter by the name dogName.
Then, add the following line to the method block:
this.Name = dogName;
This line sets this object’s property Name to the parameter we sent into the constructor.
Note that when you change the constructor’s signature, you get a case of the red squigglies in your Program.cs file.When we add our own explicit constructors, C# and .NET will not implicitly create a default constructor for us. In our Program.cs file, we are still creating the Dog objects using the default parameter-less constructor, which now no longer exists.
To fix this problem, we need to add a parameter to our constructor call in Program.cs. We can, for example, update our object construction line as such:
Dog myDog = new Dog(“Snoopy”);
Doing so will remove the red squigglies and allow you to run the code again. If you leave or set your breakpoint after the last code line, you can look at the Locals panel and verify that your object’s Name property has indeed been? Got it?
The program that keeps track of the attributes above for pet records at the animal clinic is in explanation part.
What is programming?Making a set of instructions that instruct a computer how to carry out a task is the process of programming. Computer programming languages like JavaScript, Python, and C++ can all be used for programming.
The program can be:
public class Pet {
private String name;
private int age;
private double weight;
private String type;
private String breed;
public Pet() {
}
/**
* param name
* param age
* param weight
* param type
* param breed
*/
public Pet(String name, int age, double weight, String type, String breed) {
this.name = name;
this.age = age;
this.weight = weight;
this.type = type;
this.breed = breed;
}
/**
* return the name
*/
public String getName() {
return name;
}
/**
* param name
* the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* return the age
*/
public int getAge() {
return age;
}
/**
* param age
* the age to set
*/
public void setAge(int age) {
this.age = age;
}
/**
* return the weight
*/
public double getWeight() {
return weight;
}
/**
* param weight
* the weight to set
*/
public void setWeight(double weight) {
this.weight = weight;
}
/**
* return the type
*/
public String getType() {
return type;
}
/**
* param type
* the type to set
*/
public void setType(String type) {
this.type = type;
}
/**
* return the breed
*/
public String getBreed() {
return breed;
}
/**
* param breed
* the breed to set
*/
public void setBreed(String breed) {
this.breed = breed;
}
/*
* (non-Java)
*
*/
public String toString() {
return "Pet :: Name=" + name + ", age=" + age + ", weight=" + weight
+ ", type=" + type + ", breed=" + breed;
}
}

Build a class and a driver for use in searching your computer’s secondary storage (hard disk or flash memory) for a specific file from a set of files indicated by a starting path. Lets start by looking at a directory listing. Note that every element is either a file or a directory.
Introduction and Driver
In this assignment, your job is to write a class that searches through a file hierarchy (a tree) for a specified file. Your FindFile class will search a directory (and all subdirectories) for a target file name.
For example, in the file hierarchy pictured above, the file "lesson.css" will be found once in a directory near the root or top-level drive name (e.g. "C:\") . Your FindFile class will start at the path indicated and will search each directory and subdirectory looking for a file match. Consider the following code that could help you build your Driver.java:
String targetFile = "lesson.css";
String pathToSearch ="
C:\\WCWC"; FindFile finder = new FindFile(MAX_NUMBER_OF_FILES_TO_FIND);
Finder.directorySearch(targetFile, pathToSearch);
File Searching
In general, searching can take multiple forms depending on the structure and order of the set to search. If we can make promises about the data (this data is sorted, or deltas vary by no more than 10, etc.), then we can leverage those constraints to perform a more efficient search. Files in a file system are exposed to clients of the operating system and can be organized by filename, file creation date, size, and a number of other properties. We’ll just be interested in the file names here, and we’ll want perform a brute force (i.e., sequential) search of these files looking for a specific file. The way in which we’ll get file information from the operating system will involve no ordering; as a result, a linear search is the best we can do. We’d like to search for a target file given a specified path and return the location of the file, if found. You should sketch out this logic linearly before attempting to tackle it recursively.
FindFile Class Interface
FindFile(int maxFiles): This constructor accepts the maximum number of files to find.
void directorySearch(String target, String dirName): The parameters are the target file name to look for and the directory to start in.
int getCount(): This accessor returns the number of matching files found
String[] getFiles(): This getter returns the array of file locations, up to maxFiles in size.
Requirements
Your program should be recursive.
You should build and submit at least two files: FindFile.java and Driver.java.
Throw an exception (IllegalArgumentException) if the path passed in as the starting directory is not a valid directory.
Throw an exception if you've found the MAX_NUMBER_OF_FILES_TO_FIND and catch and handle this in your main driver. Your program shouldn't crash but rather exit gracefully in the unusual situation that we've discovered the maximum number of files we were interested in, reporting each of the paths where the target files were found.
The only structures you can use in this assignment are basic arrays and your Stack, Queue, or ArrayList from the previous homeworks. Do not use built-in data structures like Java's ArrayList. To accomplish this, put in the following constructor and method to your ArrayList, Stack, or Queue:
public ArrayList(Object[] input) { data = input;
numElements = input.length;
}
public Object get(int index) {
return data[index];

size_t found = vect.at(i).find(ch);
if (found != string::npos){

}
Explanation:
This declares the length of vector as integer
int len;
This prompts the user for length
cout<<"Length: "; cin>>len;
This declares input as string
string inpt;
This declares string vector
vector<string> vect;
The following iteration gets input into the vector
for(int i =0;i<len;i++){
cin>>inpt;
vect.push_back(inpt); }
This declares ch as character
char ch;
This prompts the user for character
cout<<"Input char: "; cin>>ch;
The following iterates through the vector
for(int i =0;i<len;i++){
This checks if vector element contains the character
size_t found = vect.at(i).find(ch);
If found:

Example: Assume the user enters the following scores: 10, 5, 20. The scores are entered once at the time in the top text-box; when a score is entered, the user presses the button to "Read" the score. The score is taken by the program and the text-box is cleared, so that the next score can be entered. This process can be repeated as many times as the user wants and for as many scores as the user wants. Once all the scores are entered and read(or taken-in)by the program, the user clicks on the second button to display the results. The program should then display the two highest scores, among the ones entered. So, in the example, this would be 10, 20. And it should display the total number of scores entered by the user. In the example, it would be 3.
After that, the user should be able to repeat the process and enter a new set of scores, if wanted. The program should therefore be ready to take in new inputs and start the process again. When the user starts typing the new score, the text-boxes with the previous results (two highest scores and total num. of scores) should get cleared

Answer:
See text attachment for complete source code (for the answer) where I used comments to explain each line of the program
Explanation:
First, design the form using the following tools (and the accompanying properties) :
1 Label: Property: Text: Score
2 Buttons
Button1: Property: Name: btnAdd; Text: Add
Button2: Property: Name: btnDisplay; Text: Display
1 ListBox: Property: Visible: Hidden
1 TextBox: Property: Name: txtNum1
First, create the following function.
The function (named typecheck) validates input from the user (i.e. integer input only)
Function typecheck(ByVal input As String) As Boolean
Try
Convert.ToInt32(input)
[tex]Return\ True[/tex]
[tex]Catch\ ex\ As\ Exception[/tex]
[tex]Return\ False[/tex]
End Try
End Function
It returns true if the input is integer and false, if otherwise.
Next, double-click on the "Add" button and write the following lines of code:
Dim num1 As String
num1 = txtNum1.Text
If num1 IsNot String.Empty Then
If typecheck(num1) Then
[tex]ListBox1.Items.Add(num1)[/tex]
[tex]txtNum1.Text = String.Empty[/tex]
Else
[tex]MsgBox("Only[/tex] [tex]Integer[/tex] [tex]Inpu t")[/tex]
[tex]txtNum1.Text = String.Empty[/tex]
[tex]End\ If[/tex]
Else
[tex]MsgBox("Box[/tex] [tex]can\ not\ be\ empty")[/tex]
[tex]txtNum1.Text = String.Empty[/tex]
[tex]End\ If[/tex]
Next, double-click on the "Display" button and write the following lines of code:
If ListBox1.Items.Count > 0 Then
[tex]Dim\ max1, max2\ As\ Integer[/tex]
max1 = Convert.ToInt32(ListBox1.Items(0))
max2 = Convert.ToInt32(ListBox1.Items(0))
[tex]For\ count\ = 0\ To\ ListBox1.Items.Count - 1[/tex]
If Convert.ToInt32(ListBox1.Items([tex]count[/tex])) >= max1 Then
max1 = Convert.ToInt32(ListBox1.Items([tex]count[/tex]))
[tex]End\ If[/tex]
Next
[tex]For\ count\ = 0\ To\ ListBox1.Items.Count - 1[/tex]
If Convert.ToInt32(ListBox1.Items([tex]count[/tex])) >= max2 And Convert.ToInt32(ListBox1.Items([tex]count[/tex])) < max1 Then
max2 = Convert.ToInt32(ListBox1.Items([tex]count[/tex]))
[tex]End\ If[/tex]
Next
MsgBox("Highest Scores: " + max1.ToString() + " " + max2.ToString())
MsgBox("[tex]Total[/tex]: " + ListBox1.Items.Count.ToString())
[tex]End\ If[/tex]
ListBox1.Items.Clear()
