How do I return a character an inputted number of times?

Question

import java.util.Scanner;

public class myLine {

public static void main(String[] args) {
    String CurrentLine = new String();
    int length =0;

     Scanner sc = new Scanner(System.in);
        int x = sc.nextInt();

        if (CurrentLine.charAt(0) == 'l') {
            return '*' x times;
        }
    }

}

The last line is just me taking note of what I want to do. If the user puts in a number for x, how do I return the * character that many times?

Did you miss some code when you copied and pasted? You talk about returning, but you didn't post any method that returns anything. Where are you trying to return a String to? — Dan Getz, May 31 '15 at 03:16
Oh like I said, the last line means nothing code-wise. It's just there to remind me that I want to return a character x number of times which is what I don't know how to do — magicfan04, May 31 '15 at 03:27

You can't return in main (it's a void method). You aren't using length, and if I understand your question you could use a StringBuilder and a simple for loop. Then print the contents of the StringBuilder. Something like

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    int x = sc.nextInt();
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < x; i++) {
        sb.append('*');
    }
    System.out.println(sb.toString());
}
