[Java] Ho to get a sub array from an array with start index and end index?

Using Array util method Arrays.copyOfRange we can create a sub array. It takes originalArray, fromIndex, toIndex as inouts and return a new array. Following code shows how to use it

Note: toIndex is exclusive, i.e element at that index is not included.

import java.util.Arrays;

public class JavaArrays {
	public static void main(String[] args) {
		int[] numbers = { 45, 22, 67, 90, 47, 88 };

		int fromIndex = 1;
		int toIndex = 3;
		int[] subArray = Arrays.copyOfRange(numbers, fromIndex, toIndex);
		
		System.out.println("Subarray is: " + Arrays.toString(subArray));
	}
}

Output:

Subarray is: [22, 67]
