Question

In JAVA

1. Create a class called Rectangle that has integer data members named - length and width. Your class should have a default constructor (no arg constructor) Rectangle() that initializes the two instance variables of the object Rect1. The second overloading constructor should initializes the value of the second object Rect2. The class should have a member function named GetWidth() and GetLength() that display rectangle's length and width. OUTPUT: Rectl width: 5 Rectl length: 10 Enter a width : 20 Enter a length: 50 Rect2 width : 20 Rect2 length: 50 JAVA 2. Create a class called Date that includes three instance variables-- a month (type int), a day (type int), and a year (type int ). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (1) Write a test application named Date Test that demonstrates class Date's capabilities. OUTPUT: The initial date is: 7/4/2004 Date with new values is: 11/1/2003

import java.util.Scanner;

public class Rectangle {

    private int width;
    private int length;

    public Rectangle() {
        width = 5;
        length = 10;
    }

    public Rectangle(int width, int length) {
        this.width = width;
        this.length = length;
    }

    public int getWidth() {
        return width;
    }

    public int getLength() {
        return length;
    }

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        Rectangle rectangle1 = new Rectangle();
        System.out.println("Rect1 width: " + rectangle1.getWidth());
        System.out.println("Rect1 length: " + rectangle1.getLength());
        System.out.print("Enter a width: ");
        int width = in.nextInt();
        System.out.print("Enter a length: ");
        int length = in.nextInt();
        Rectangle rectangle2 = new Rectangle(width, length);
        System.out.println("Rect2 width: " + rectangle2.getWidth());
        System.out.println("Rect2 length: " + rectangle2.getLength());
    }
}

Rect1 width: 5 Recti length: 10 Enter a width: 20 Enter a length: 50 Rect2 width: 20 Rect2 length: 50 Process finished with exit code o
