Sorting char array in Java example

In this example we are sorting a char array. We have demonstrated two types of sorting in the program 1) Complete sorting using sort(char[] a) method 2) Sorting specified range of characters only using sort(char[] a, int fromIndex, int toIndex) method.

import java.util.Arrays;

class SortCharArray {

  public static void main(String[] args) {
 
    // Creating a Char Array
    char[] charArray = new char[] { 'A', 'Q', 'S', 'Z', 'P' };
 
    // Displaying Array before Sorting
    System.out.println("**Char Array Before Sorting**");
    for (char ch: charArray){
       System.out.println(ch);
    }

    // Sorting the Array
    Arrays.sort(charArray);
    System.out.println("**Char Array After Sorting**");
    for (char ch: charArray){
       System.out.println(ch);
    }
 
    // Another Char Array
    char[] charArray2 = 
        new char[] { 'D', 'F', 'V', 'J', 'U', 'M', 'C' };
 
    // Selective Sorting
    /* public static void sort(char[] a, int fromIndex,
     * int toIndex): Sorts the specified range of the 
     * array into ascending order. The range to be sorted 
     * extends from the index fromIndex, inclusive, to the 
     * index toIndex, exclusive. If fromIndex == toIndex, 
     * the range to be sorted is empty.
     */
    Arrays.sort(charArray2, 2, 5);

    // Displaying array after selective sorting 
    System.out.println("**Selective Sorting**");
    for (char ch: charArray2){
       System.out.println(ch);
    }
  }
}

Output:

**Char Array Before Sorting**
A
Q
S
Z
P
**Char Array After Sorting**
A
P
Q
S
Z
**Selective Sorting**
D
F
J
U
V
M
C
