How to sort elements in Character Array in Java?

Declaration :

public static void sort(char[] a)

1	public static void sort(char[] a)

Explanation :

Purpose	The java.util.Arrays.sort(char[]) method sorts the specified array of chars into ascending numerical order.
Parameters	a ===> This is the array to be sorted.
Return Value	This method does not return any value.
Exception	NA

Java Program : Example

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

package com.c4learn;
import java.util.Arrays;
public class ArrayDemo {
   	public static void main(String[] args) {
		// Initialize unsorted char array
		char chArr[] = { 'c', 'a', 'b', 'd' };
		// Print the Unsorted Array List
		System.out.println("The unsorted char array is:");
		for (char val : chArr) {
			System.out.println("Value = " + val);
		}
		// Sort the array
		Arrays.sort(chArr);
		// Print the Sorted Array List
		System.out.println("The sorted char array is:");
		for (char val : chArr) {
			System.out.println("Value = " + val);
		}
	}
}

package com.c4learn;

import java.util.Arrays;

public class ArrayDemo {

public static void main(String[] args) {

// Initialize unsorted char array

char chArr[] = { 'c', 'a', 'b', 'd' };

// Print the Unsorted Array List

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

for (char val : chArr) {

System.out.println("Value = " + val);

}

// Sort the array

Arrays.sort(chArr);

// Print the Sorted Array List

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

for (char val : chArr) {

System.out.println("Value = " + val);

}

Output of Program :

The unsorted char array is:
Value = c
Value = a
Value = b
Value = d
The sorted char array is:
Value = a
Value = b
Value = c
Value = d

The unsorted char array is:

Value = c

Value = a

Value = b

Value = d

The sorted char array is:

Value = a

Value = b

Value = c

Value = d
