In this article, we will discuss how to sort byte[] Arrays with example
1. Byte:
- Size is 1 byte
- Its range is -128 to 127
Arrays class has various sort methods for sorting different primitive data-types
2. Sorting byte[] Arrays :
- To sort byte[] array, we have 2 variant of sort methods from Arrays class
Method Signature:
1 2 3 | public static void sort(byte[] a);public static void sort(byte[] a, int fromIndex, int toIndex); |
3. Sorting method for byte[] Arrays :
| Sort method |
Description |
| sort(byte[]); | sorts complete byte[] array |
| sort(b[], sIndex, eIndex); | sorts partial byte[] array as per limits start-index & end-index specified in the method arguments |
Let us move forward to discuss both methods for sorting byte[] array
4. Example for byte[] Arrays Sorting :
- Complete/full Sorting of byte[] Arrays
- Partial Sorting of byte[] Arrays
4.1 Complete/Full Sorting of byte[] Arrays :
- Here, complete arrays will be sorted
Method Signature:
1 | public static void sort(byte[] a); |
SortingCompleteByteArray.java
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | package in.bench.resources.java.arrays.sorting;import java.util.Arrays;public class SortingCompleteByteArray { public static void main(String[] args) { // sample byte[] array byte[] bArray = {14, 1, 29, 7, 13, 23, 17}; // before sorting System.out.println("Before sorting : "); for(byte b : bArray) { System.out.print(b + " "); } // sorting full byte[] array Arrays.sort(bArray); // after sorting System.out.println("\n\nAfter sorting : "); for(byte b : bArray) { System.out.print(b + " "); } }} |
Output:
1 2 3 4 5 | Before sorting :14 1 29 7 13 23 17After sorting :1 7 13 14 17 23 29 |
4.2 Partial Sorting of byte[] Arrays :
- This is the another variant to sort arrays where we can specify start & end limits within byte[] array
Method Signature:
1 | public static void sort(byte[] a, int fromIndex, int toIndex); |
SortingPartialByteArray.java
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | package in.bench.resources.java.arrays.sorting;import java.util.Arrays;public class SortingPartialByteArray { public static void main(String[] args) { // sample byte[] array byte[] bArray = {14, 1, 29, 7, 13, 23, 17}; // before sorting System.out.println("Before sorting : "); for(byte b : bArray) { System.out.print(b + " "); } // partial sorting of byte[] array Arrays.sort(bArray, 1, 6); // after sorting System.out.println("\n\nAfter sorting : "); for(byte b : bArray) { System.out.print(b + " "); } }} |
Output:
1 2 3 4 5 | Before sorting :14 1 29 7 13 23 17 After sorting :14 1 7 13 23 29 17 |
Explanation:
- Here, there are 7 byte elements in byte[] array
- But, we have sorted byte[] array starting from index-1 till index-5 leaving 1st & last elements
- Therefore, 1st and last element remains as it is after sorting and only middle elements are sorted
