Question

Define a class TwoD which contains the following methods:

i) void rect(int L, int B) - Calculate the area of the rectangle

ii) void circ(int R) - Calculate the area of circle.

Invoke both the methods from main function and display the area of both rectangle and

circle.​

Answer 1

public class TwoD {

void rect(int L, int B) {

System.out.println("Area of Rectangle - " + (L * B));

}

void circ(int R) {

System.out.println("Area of Rectangle - " + (Math.PI * R * R));

}

public static void main(String[ ] args) {

TwoD area = new TwoD( );

area.rect(12, 13);

area.circ(12);

}

}
