Java Arrays class provides few utility methods. One of the utility method Arrays.copyOfRange() helps us to copy range of object from existing array to new array. Below example shows how to copy range of object to new array.

package com.java2novice.arrays;

import java.util.Arrays;

public class MyArrayRangeCopy {
	public static void main(String a[]){
		int[] myArr = {2,4,2,4,5,6,3};
		System.out.println("My array elements:\n");
		for(int num:myArr){
			System.out.print(num+"  ");
		int[] newArr = Arrays.copyOfRange(myArr, 1, 4);
		System.out.println("\nMy new array elements:\n");
		for(int num:newArr){
			System.out.print(num+"  ");

My array elements:
