Convert a Boolean Array to String in Java

Declaration :

public static String toString(boolean[] a)

1	public static String toString(boolean[] a)

Explanation :

Purpose	The java.util.Arrays.toString(boolean[]) method returns a string representation of the contents of the specified boolean array. The string representation consists of a list of the array’s elements enclosed in square brackets (“[]”). Adjacent elements are separated by the characters ” ” (a comma followed by a space).
Parameters	a ===> This is the array whose string representation to return.
Return Value	This method returns a string representation of a.
Exception	NA

Java Program : Example

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

package com.c4learn;
import java.util.Arrays;
public class ArrayDemo {
	public static void main(String[] args) {
		// Initialize a boolean array
		boolean[] arrB = new boolean[] { true, false, false, true };
		// let us print all the values available in list
		System.out.println("The array is:");
		for (boolean val : arrB) {
			System.out.println("Element is " + val);
		}
		System.out.println("String Representation :");
		System.out.println(Arrays.toString(arrB));
	}
}

package com.c4learn;

import java.util.Arrays;

public class ArrayDemo {

public static void main(String[] args) {

// Initialize a boolean array

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

// let us print all the values available in list

System.out.println("The array is:");

for (boolean val : arrB) {

System.out.println("Element is " + val);

}

System.out.println("String Representation :");

System.out.println(Arrays.toString(arrB));

}

Output of Program :

The array is:
Element is true
Element is false
Element is false
Element is true
String Representation :
[true, false, false, true]

The array is:

Element is true

Element is false

Element is true

String Representation :

[true, false, false, true]
