Remove Last Element of Array in Java

Java – Remove Last Element of Array

To remove the last element of an Array in Java, call Arrays.copyOf() method and pass the array and new size as arguments. The new size must be one less than the size of original array.

Examples

In the following example, we take an integer array and create a new array with the last element removed from the original array using Arrays.copyOf() method.

Main.java

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        int arr[] = {2, 4, 6, 8};
        
        int newArr[] = Arrays.copyOf(arr, arr.length - 1);

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

Output

Original  : [2, 4, 6, 8]
New Array : [2, 4, 6]
