   {
      String strInput = "flowerbrackets";
      // converting string to char array
      char[] ch = strInput.toCharArray();
      // sorting char array
      Arrays.sort(ch);
      // converting char array to string

Example 2: string sorting in java

public class ArrayReturn3 {
 
    public static String[] sortNames(String[] userNames) {
        String temp;
        for (int i = 0; i < userNames.length; i++) {
            for (int j = i + 1; j < userNames.length; j++) {
                if (userNames[i].compareTo(userNames[j]) > 0) {
                    temp = userNames[i];
                    userNames[i] = userNames[j];
                    userNames[j] = temp;
                }
            }
        }
        return userNames;
    }
 
    public static void main(String[] args) {
        String[] names = {"Ram", "Mohan", "Sohan", "Rita", "Anita", "Nita", "Shyam", "Mukund"};
        System.out.println("Names before sort");
        for (String n : names) {
            System.out.print(" " + n);
        }
        String[] sortedNames = sortNames(names);
        System.out.println("\nNames after sort (Sent name)");
        for (String n : names) {
            System.out.print(" " + n);
        }
        System.out.println("\nNames after sort (Received name)");
        for (String n : sortedNames) {
            System.out.print(" " + n);
        }
