Answer:

public class Main

{

public static void main(String[] args) {

 System.out.println(starString(4));

}

public static String starString(int n){

    double p = Math.pow(2,n);

    String s = "";

    for(int i=0; i<p; i++)

        s += "*";

       

   return s;

}

}

Explanation:

Create a method named starString that takes an integer parameter, n

Get the 2 to the nth power using pow method and set it to the p

Create an empty string that will hold the asterisks

Create a for loop that will iterate p times. Inside the loop, concatenate an asterisk to the s

Return the s

Inside the main method, call the method with an integer parameter
