Answer to Question #287938 in Java | JSP | JSF for Yash

Question

Write a program to create a class Rectangle with the following information:

length, breadth in integer.

• Add two constructors, (a) default constructor, and (b) constructor to pass on length

and breadth of a Rectangle.

• Add a method printData( ) to print the two information about the rectangle in

console.

• Add methods printArea( ) and printPerimeter( ) to compute and print the area and

perimeter of rectangle in console.

• Create two objects of this class, r1 and r2. Show the output of both the constructors

and all method of these two objects

Answer 1

public class Rectangle {
    private int length;
    private int breadth;

    public Rectangle() {
        length = 0;
        breadth = 0;
    }

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

    public void printData() {
        System.out.println("Length: " + length + ", Breadth: " + breadth);
    }

    public void printArea() {
        System.out.println("Area: " + length * breadth);
    }

    public void printPerimeter() {
        System.out.println("Perimeter: " + 2 * (length + breadth));
    }
}

public class Main {
    public static void main(String[] args) {
        Rectangle r1 = new Rectangle();
        r1.printData();
        r1.printArea();
        r1.printPerimeter();
        Rectangle r2 = new Rectangle(10, 5);
        r2.printData();
        r2.printArea();
        r2.printPerimeter();
    }
}
