Java Program to Find Square and Cube of a Number (N^1, N^2, N^3)

Method 2:- Using Power Function

import java.util.Scanner;
import java.lang.*;

public class threenum1
{
    public static void main(String args[])
    {
        int num;
  double a,b,c; 
    
  Scanner sc = new Scanner(System.in);
 
        System.out.print("Enter The Number :\n\n");
        num = sc.nextInt();

  a=Math.pow(num,1);
  b=Math.pow(num,2);
  c=Math.pow(num,3);

  System.out.println("\nOutput Is = " + a + " ,"+ b +" ,"+ c +"\n\n"); 
 }
}

Output:

Enter The Number :

10

Output Is = 10.0 ,100.0 ,1000.0

Method 1:- Simple Without Using Power Function

import java.util.Scanner;
import java.lang.*;

public class threenum
{
    public static void main(String args[])
    {
        int num,a,b,c; 
        Scanner sc = new Scanner(System.in);
 
        System.out.print("Enter The Number :\n\n");
        num = sc.nextInt();
 
  a=num;
  b=num*num;
  c=num*num*num;

  System.out.println("\nOutput Is = " + a + " ,"+ b +" ,"+ c +"\n\n"); 
 }
} 

Output:

Enter The Number :

5

Output Is = 5 ,25 ,125
