Slice an Array in Java

Java – Slice an Array

To slice an array from specific starting index to specific ending index, call Arrays.copyOfRange() method and pass the array, starting index, and ending index as arguments.

Examples

In the following example, we take an integer array of length 10 and slice it from index=3 to index=8.

Main.java

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        int arr[] = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20};
        int start = 3;
        int end = 8;

        int newArr[] = Arrays.copyOfRange(arr, start, end);

        System.out.println("Original : " + Arrays.toString(arr));
        System.out.println("Sliced   : " + Arrays.toString(newArr));
    }
}

Output

Original : [2, 4, 6, 8, 10, 12, 14, 16, 18, 20]
Sliced   : [8, 10, 12, 14, 16]
