Program 1: WAP to print a message


class P1 {
    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

Copy Code

Expected Output:
Hello World!

Program 2: To find the volume of a cuboid with user input of l, b, and h


import java.util.*;

class P2 {
    public static void main(String[] args) {
        int l, b, h, v;

        Scanner sc = new Scanner(System.in);

        System.out.print("Enter length : ");
        l = sc.nextInt();

        System.out.print("Enter breadth : ");
        b = sc.nextInt();

        System.out.print("Enter height : ");
        h = sc.nextInt();

        v = l * b * h;

        System.out.print("Volume of Cuboid is : " + v);

    }
}

Copy Code

Expected Output:
Enter length : 5
Enter breadth : 4
Enter height : 3

Volume of Cuboid is : 60

Program 3: WAP to find the volume of a cuboid without user input


class P3 {
    public static void main(String[] args) {
        int l, b, h, v;

        l = 45;
        b = 23;
        h = 21;

        v = l * b * h;

        System.out.println("Volume of Cuboid is : " + v);

        System.out.print(
                "Volume of Cuboid which length is " + l + " breadth is " + b + " and height is " + h + " is : " + v);

    }
}

Copy Code

Expected Output:
Volume of Cuboid is : 20745

Volume of Cuboid which length is 45 breadth is 23 and height is 21 is : 20745

Program 4: WAP to find the area of a square


import java.util.*;

class P4 {
    public static void main(String[] args) {

        int s, a;

        Scanner sc = new Scanner(System.in);

        System.out.print("Enter side : ");

        s = sc.nextInt();
        a = s * s;

        System.out.println("Area of Square : " + a);

    }
}

Copy Code

Expected Output:
Enter side : 5

Area of Square : 25
