Write the definition of a method named printpoweroftwostars that receives a non-negative integer n and prints a string consisting of "2 to the n" asterisks. so, if the method received 4 it would print 2 to the 4 asterisks, that is, 16 asterisks: and if it received 0 it would print 2 to the 0 (i. e. 1) asterisks:

import java.io.*;

import java.util.*;

import java.lang.Math;

class GFG {

   public static void PowerOfTwoStars(int n){

       double a=Math.pow(2,n); //calculating the power..

       for (int i=1;i<=a;i++)//looping to print the stars.

       {

           System.out.print("*");

       }

   }

public static void main (String[] args) {

    Scanner star=new Scanner(System.in);//creating the scanner class object.

    int n=star.nextInt();//taking input.

    PowerOfTwoStars(n);//calling the function.

}

}

Input:-

3

Output:-

Explanation:

In the method PowerOfTwoStars which contains one argument I have calculated the power that is 2 to the n.Then looping form 1 to power and printing the stars and for better explanation please refer the comments the code.
