Copy the range of Boolean Array to another array in Java

Declaration :

public static boolean[] copyOfRange(boolean[] original, int from, int to)

1	public static boolean[] copyOfRange(boolean[] original, int from, int to)

Explanation :

Purpose	The java.util.Arrays.copyOfRange(boolean[] original int from int to) method copies the specified range of the specified array into a new array.The final index of the range (to) which must be greater than or equal to from may be greater than original.length in which case false is placed in all elements of the copy whose index is greater than or equal to original.length - from. The length of the returned array will be to - from.
Parameters	original ===> This is the array from which a range is to to be copied.
	from ===> This is the initial index of the range to be copied inclusive.
	to ===> This is the final index of the range to be copied exclusive.
Return Value	This method returns a new array containing the specified range from the original array truncated or padded with false elements to obtain the required length.
Exception	ArrayIndexOutOfBoundsException — If from < 0 or from > original.length() ,IllegalArgumentException — If if from > to. ,NullPointerException — If original is null.

Java Program : Example

Below example will explain java.util.Arrays.copyOfRange() method.

package com.c4learn;
import java.util.Arrays;
public class ArrayDemo {
	public static void main(String[] args) {
		// Initialize a Boolean Array
		boolean[] arr1 = new boolean[] { false, true, true, false };
		// Print first array
		System.out.println("First array:");
		for (int i = 0; i < arr1.length; i++) {
			System.out.println(arr1[i]);
		}
		// Copy the array elements to new array with range 0 to 8
		boolean[] arr2 = Arrays.copyOfRange(arr1, 0, 8);
		// Print the new array
		System.out.println("New array:");
		for (int i = 0; i < arr2.length; i++) {
			System.out.println(arr2[i]);
		}
	}
}

package com.c4learn;

import java.util.Arrays;

public class ArrayDemo {

public static void main(String[] args) {

// Initialize a Boolean Array

boolean[] arr1 = new boolean[] { false, true, true, false };

// Print first array

System.out.println("First array:");

for (int i = 0; i < arr1.length; i++) {

System.out.println(arr1[i]);

}

// Copy the array elements to new array with range 0 to 8

boolean[] arr2 = Arrays.copyOfRange(arr1, 0, 8);

// Print the new array

System.out.println("New array:");

for (int i = 0; i < arr2.length; i++) {

System.out.println(arr2[i]);

}

Output of Program :

First array:
false
true
true
false
Printing new array:
false
true
true
false
false
false
false
false

First array:

false

true

false

Printing new array:

false

true

false
