Convert a Character Array to String in Java

Declaration :

public static String toString(char[] a)

1	public static String toString(char[] a)

Explanation :

Purpose	The java.util.Arrays.toString(char[]) method returns a string representation of the contents of the specified char 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 character array
		char[] arrCh = new char[] { 'a', 'b', 'c' };
		// Print the character array
		System.out.println("The array is:");
		for (char val : arrCh) {
			System.out.println("Element is " + val);
		}
		System.out.println("\nString Representation :");
		System.out.println(Arrays.toString(arrCh));
	}
}

package com.c4learn;

import java.util.Arrays;

public class ArrayDemo {

public static void main(String[] args) {

// Initialize a character array

char[] arrCh = new char[] { 'a', 'b', 'c' };

// Print the character array

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

for (char val : arrCh) {

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

}

System.out.println("\nString Representation :");

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

}

Output of Program :

The array is:
Element is a
Element is b
Element is c
String Representation :
[a, b, c]

The array is:

Element is a

Element is b

Element is c

String Representation :

[a, b, c]
