The point of this assignment is to cover a few of the basic principles of encapsulation.

Using the IDE

Remember that all code must be submitted in text format.

Initial Code & Output

Load the following code into the online compiler:

https://www.jdoodle.com/online-java-compiler/

Please copy the following code into the IDE, compile and run it.

// calculate area of rectangle using class in java

import java.io.*;

import java.util.Scanner;

public class EncapsulationDemo

{

public static void main(String[] args)

{

// Create object of Rectangle class

System.out.println(A09 Written by Matt Weisfeld
);

Scanner console = new Scanner(System.in);

// Input Strings

String len=null, wid=null;

int l=0,w=0;

// Remove Comment to Create the Rectangle

// Rectangle rect = new Rectangle(0, 0);

// Begin while() loop here

System.out.println(
Bye);

}

}

This code covers a lot of programming concepts. Please take this opportunity to study the code and determine what is going on.

When you execute the code it will look something like this:

Problem

Note that this is simply a shell to get you started with a clean compile.

The task is to create a Rectangle class that follows the following UML specification.

Here are the constraints that you must include in your program.

• Include an output statement at the beginning of the program with the assignment number and your name:
• Create a single Rectangle object called rect.
• Implement a while() loop to accept User input for multiple area calculations (reset rect).
• Implement a break statement to terminate the loop.
• Each time through the loop, accept user input for 2 integer variables, length (first) and width.
• Terminate the loop when the user enters x for the length (no need to enter width).
• Calculate the area of the current rect.
• Print the area to the console (using rectss getArea() method).
• Print out an exit greeting (Bye) when exiting the application.

Final Output

Once completed, your output (in the following test case) should look like this:
