This example shows 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.util;

import java.util.Arrays;

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

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

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

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

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

**********

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

public class Test {
    public static void main(String[] args) {
        String str = new String(new char[10]).replace('\u0000', '*');
    }
}

Or

import java.util.Collections;

public class Test {
    public static void main(String[] args) {
        String str = String.join("", Collections.nCopies(10, "*"));
    }
}
