Ordenar la matriz de caracteres en el ejemplo de Java

En este ejemplo, estamos ordenando una matriz de caracteres. Hemos demostrado dos tipos de clasificación en el programa 1) Clasificación completa usando sort (char[] a) método 2) Ordenar el rango especificado de caracteres usando solo sort (char[] a, int fromIndex, int toIndex) método.

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);
    }
  }
}
