This example show you how to create a repeated sequence of characters. To do this we use the Arrays.fill() method. This method fills an array of char with a character.

package org.kodejava.example.util;

import java.util.Arrays;

public class RepeatCharacterExample {
    public static void main(String[] args) {
        char c = 'x';
        int length = 10;

        // creates char array with 10 elements
        char[] chars = new char[length];

        // fill each element of chars array with 'x'
        Arrays.fill(chars, c);

        // print out the repeated 'x'
        System.out.println(String.valueOf(chars));
    }
}

As the result you get the x character repeated 10 times.

xxxxxxxxxx

For one liner code you can use the following code snippet, which will give you the same result.

new String(new char[10]).replace('\u0000', 'x');

Or

String.join("", Collections.nCopies(10, "x"));
