Sort a string in alphabetical order

In this java program, we’re to going to sort a String in alphabetical order. First, we will take String input from the user and store it in the variable “s” (in this case). After that we will convert String to character array using tocharArray() method then we’re using sort() method present in Arrays class to sort the string.

for example, if we take a string prepinsta then sorted string is ‘aeinpprst’ , if we take coding then sorted string is ‘cdgino’.

Java program to Sorting a string in alphabetical order

Algorithm

  • Take a String input from user and store it in the variable called “s” (in this case)
  • After that convert String to character array using tocharArray() method
  • Use Arrays class sort method to sort() the character array
  • At last print sorted array System.out.println(c)

Code in Java

import java.util.Arrays;
import java.util.Scanner;
public class SortAStringAlphabetically {

public static void main(String[] args){
    Scanner sc = new Scanner(System.in);
    System.out.print("Enter String :");
    String s = sc.nextLine();
    char[] c = s.toCharArray(); 
    Arrays.sort(c);
    System.out.println(c);
  }
}

Output

Enter String :prepinsta
