Arrays Fill 

The following example shows how to use Arrays.fill API. We can either fill the entire array with specified character or just a specified range. Here fromIndex is the index of the first element (inclusive) to be filled with the specified value and toIndex is the index of the last element (exclusive) to be filled with the specified value.

package com.bethecoder.tutorials.utils.arrays; import java.util.Arrays; public class ArraysFill {   public static void main (String [] args) {          char [] charArray = new char [6];     System.out.println("Before fill : " + Arrays.toString(charArray));          Arrays.fill(charArray, 'a');     System.out.println("Filled array : " + Arrays.toString(charArray));          Arrays.fill(charArray, 1, 5, 'b');     System.out.println("Filled array : " + Arrays.toString(charArray));        } }

Before fill : [ø, ø, ø, ø, ø, ø]
Filled array : [a, a, a, a, a, a]
Filled array : [a, b, b, b, b, a]
