This post will show you how to copy a subset elements of an array by range. For example, copy elements from index 3 to 4 (exclusive). The range values work in the same way as the String‘s substring method.

Using Arrays.copyOfRange

The java.util.Arrays has numerous helpful methods such as copyOfRange.

package com.turreta.array;

import java.util.Arrays;

public class CopyOfRangeArrayDemo {

    public static void main(String[] args) {
        String[] originalArray = { "I", "want", "to", "break", "free" };

        String[] subSetArray = Arrays.copyOfRange(originalArray, 2, 4);

        System.out.println(Arrays.toString(subSetArray));

    }
}
