Sort byte array in Java

This is the example of sorting a byte array in Java. Here we have done two types of sorting 1) complete sorting using sort(byte[] a) method 2) Selective sorting using sort(byte[] a, int fromIndex, int toIndex) method – It sorts the specified range only. Refer comments in the program for more detail.

import java.util.Arrays;

class SortByteArray {

  public static void main(String[] args) {
 
    // Creating a Byte Array
    byte[] byteArray = new byte[] { 13, 9, 15, 24, 4 };
 
    // Displaying Array before Sorting
    System.out.println("**byte Array Before Sorting**");
    for (byte temp: byteArray){
       System.out.println(temp);
    }

    // Sorting the Array
    Arrays.sort(byteArray);
    System.out.println("**byte Array After Sorting**");
    for (byte temp: byteArray){
       System.out.println(temp);
    }
 
    // Another byte Array
    byte[] byteArray2 = 
       new byte[] { 15, 22, 3, 41, 24, 77, 8, 9 };
 
    // Selective Sorting
    /* public static void sort(byte[] 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(byteArray2, 2, 5);

    // Displaying array after selective sorting 
    System.out.println("**Selective Sorting**");
    for (byte temp: byteArray2){
       System.out.println(temp);
    }
  }
}

Output:

**byte Array Before Sorting**
13
9
15
24
4
**byte Array After Sorting**
4
9
13
15
24
**Selective Sorting**
15
22
3
24
41
77
8
9
