# Java Program To Read Integer (N) And Print First Three Powers (N^1,N^2,N^3)

Problem :- Write A Java Program To Read Integer (N) And Print First Three Powers (N^1,N^2,N^3) Example If user Enter a 5 From Keyboard Then Output Should be 5 ,25 ,125 Means power of number in 1 ,2 ,3

Logic :- For this problem We Need to multiply Number or we can use power function for that take a example for better understood this problem take a Number 5 as input and multiply with same number again like 5*5 for cube we need to again multiply with same number like 5*5*5 or we can use power function

Power Function  Syntax ;- for given example  xy .

pow(x,y)

also define the datatype of x and y .

Solution :-

Method 1 :- Simple Without Using Power Function

import java.util.Scanner;

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");

}
}

{
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:-
