Recursion in java

I'm trying to accept an integer and a character. It should print out the integer that was entered and the character times the integer that was entered. Eg. if 3 and c was entered the output should be: 3 ccc. Thanks for any help. import java.util.Scanner; public class Histogram{ public static void Histogram_Recursive(int n, String c) { if(n==0) { return; } else { return n * Histogram_Recursive(n-1, c); } } public static void main(String[] args) { Scanner obj = new Scanner(System.in); System.out.println("Enter a Number: "); int number = obj.nextInt(); System.out.println("Enter a Character: "); String character = obj.next(); System.out.print("\n"); System.out.print(number +" "); Histogram_Recursive(number, character); } }

If you want to return a value you should not use void. public static int histogram... But if you want to use void then you could add a print statement At the moment I am not sure how your method works. Can you give an example with input (n & c) and the expected output?

Yes, you are welcome Taylor but... You can ask If you don't understand something in my code.

Taylor You also need to do something with the string in your recursive method.
