Slip 18 - A) Write a Java program to calculate area of Circle, Triangle & Rectangle.(Use Method Overloading)

Solution :

import java.util.*;

class AreaCalculate{

    void area(int r){

        System.out.println("Area of Cirlce = " + (3.14*r*r));

    }

    float area(int b, float h){

        return b*h/2;

    }

    double area(Float l, Float db){

        return l+db;

    }  

}

class Slip18A {

    public static void main(String args[]){

        int r, b, l, db;

        float h;

        Scanner br = new Scanner(System.in);

        System.out.println("Enter the radius, base, height, length and breadth : ");

        r = br.nextInt();

        b = br.nextInt();

        h = br.nextFloat();

        l = br.nextInt();

        db = br.nextInt();

        AreaCalculate ac = new AreaCalculate();

        ac.area(r);

        System.out.println("Area of Triangle = " +ac.area(b,h));

        System.out.println("Area of Rectange = " +ac.area(l,db));

    }

}

Output:
