How to sort elements in Character Array using Index in Java?
Declaration :
|
1 |
public static void sort(char[] a, int fromIndex, int toIndex) |
Explanation :
| Purpose | The java.util.Arrays.sort(char[] a int fromIndex int toIndex) method sorts the specified range of the specified array of chars into ascending numerical order. The range to be sorted extends from index fromIndex inclusive to index toIndex exclusive. |
| Parameters | a ===> This is the array to be sorted. |
| fromIndex ===> This is the index of the first element (inclusive) to be sorted. | |
| toIndex ===> This is the index of the last element (exclusive) to be sorted . | |
| Return Value | This method does not return any value. |
| Exception | IllegalArgumentException — if fromIndex > toIndex ,ArrayIndexOutOfBoundsException — if fromIndex < 0 or toIndex > a.length |
Java Program : Example
Below example will explain java.util.Arrays.sort() method.

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 com.c4learn; import java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { // Initialize unsorted char array char chArr[] = { 'c', 'a', 'd', 'b' }; // 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 from index 0 to 3 Arrays.sort(chArr, 0, 4); // Print the Sorted Array List System.out.println("The Sorted Char Array is:"); for (char num : chArr) { System.out.println("Values = " + num); } } } |
Output of Program :
|
1 2 3 4 5 6 7 8 9 |
The Unsorted Char Array is: Value = c Value = a Value = d Value = b The Sorted Char Array is: Values = a Values = b Values = c |
