How do I create a String with alphabetical order letters taken from another String?

Let's say I have something like this

String theWord = "Hello World";

How do I compute the new String to make it look like"


Which is theWord but sorted character by character in alphabetical order.

Thanks in advance

char[] chars = theWord.toCharArray();
String newWord = new String(chars);

Sort a String in Java (2 different ways), Java program to print Even length words in a String · Program to print half Use String class constructor to create a sorted string from char array. Note : As we know that String is immutable in java, hence in third step we have to create a new string. Arrays.sort(char c[]) method sort characters based on their ASCII value, we  Internally, String uses an array of characters to operate on. Therefore, we can make use of the toCharArray () : char [] method, sort the array and create a new String based on the result: void givenString_whenSort_thenSorted () { String abcd = "bdca"; char[] chars = abcd.toCharArray (); Arrays.sort (chars); String sorted = new String (chars);

See Arrays.sort() & toCharArray()

Sort string of characters, Java program to sort a string of characters. import java.util.Arrays;. class GFG {. // function to print string in sorted order. static void sortString(String str) {. char []arr  Conclusion : We have seen four different ways to sort the characters in a string in Java. Actually, the second and third methods are the same. You can use the third one instead of the second one to support all uppercase and lowercase letters.

Agreed, I stole the solution. But apparently, it's also important to strip whitespace and make everything lowercase:

char[] array = theWord.replaceAll("\\s+", "").toLowerCase().toCharArray();
System.out.println(new String(array));

Sorting a String Alphabetically in Java, Have a look at different ways to sort a String alphabetically in Java. could be validation if two words are composed of the same characters set. the toCharArray() : char[] method, sort the array and create a new String based  Given a String, the task is to insert another string in between the given String at a particular specified index in Java. Get the Strings and the index. Traverse the string till the specified index and copy this into the new String. Copy the remaining characters of the first string into the new String. Get the Strings and the index.

None of the above solutions are locale specific , therefore I came with this solution, it is not efficient , but it works very well..

public static String localeSpecificStringSort(String str, Locale locale) {

        String[] strArr = new String[str.length()];

        for(int i=0;i<str.length();i++){
            strArr[i] =  str.substring(i,i+1);
        Collator collator = Collator.getInstance(locale);
        Arrays.sort(strArr, collator);
        StringBuffer strBuf = new StringBuffer();
        for (String string : strArr) {
        return strBuf.toString();

Java Program to Sort Strings in an Alphabetical Order, In this java tutorial, we will learn how to sort Strings in an Alphabetical Order. Once we have all the strings stored in the string array, we are comparing the first alphabet of each string to get them scan = new Scanner(; //User will be asked to enter the count of strings Java program to reverse words in a String There are basically two ways of creating in Java-Using “new” keyword. Using String Literal. Using “new” keyword. In this a new Sting object is created every time whether we are using the same value for the string or a different value. In this case the object is created in the heap. Example of String creation using “new” String new1 = new String(“Codingeek”); Using String Literal

char[] arr = new char[theWord.length()];
for(int i=0;i<theWord.length;i++)
for(int i=0;i<theWord.length();i++)
  for(int j=0;j<theWord.length();j++)
    char temp = arr[i];
int size=theWord.length();
for(int i=0;i<size;i++)

Python Program to Sort Words in Alphabetic Order, In this program, you'll learn to sort the words in alphabetic order using for loop and Program to sort alphabetically the words form a string provided by the user cased letters" # To take input from the user #my_str = input("Enter a string: Python Examples · C Examples · Java Examples · Kotlin Examples · C++ Examples  Apply toCharArray() method on input string to create a char array for input string. Use Arrays.sort(char c[]) method to sort char array. Use String class constructor to create a sorted string from char array. Note : As we know that String is immutable in java, hence in third step we have to create a new string.

Java Programing: Solution to Programming Exercise, Then write a second list to the output file in which the words are sorted String word; // The word (in lower case letters). int count; // The number of WordData(​String w) { // Constructor creates an object with the specified word This constructor will be used whenever a new word is encountered in the file for the first time. Given a string of lowercase characters from ‘a’ – ‘z’. We need to write a program to print the characters of this string in sorted order. A simple approach will be to use sorting algorithms like quick sort or merge sort and sort the input string and print it. Time Complexity: O (n log n), where n is the length of string.

Answers to Questions and Exercises: Characters and Strings, StringBuffer sb = new StringBuffer("Able was I ere I saw Elba."); Question 2c: Write an expression that refers to the letter b in the string referred to by hannah . Exercise 3: An anagram is a word or a phrase made by transposing the letters of To make Anagram work with early * versions of the Java platform, you need to  Learn to sort an array of strings alphabetically using a simple java program. In given program, all strings are given as input from console; and after sorting, all strings are printed in the console for verifying. We are going to write a program which will work ask for number of strings, user want to sort. Then user need to enter each string

Python sorted() Function, Strings are sorted alphabetically, and numbers are sorted numerically. Note: You cannot sort a list that contains BOTH string values AND numeric values. Syntax. This program will read N strings (names) and sort them in Ascending Order. Sorting of N Strings/Names in Ascending Order using Java program. //Java program to count words in a string. import java.util.Scanner; class SortStrings { public static void main (String args []) { String temp; Scanner SC = new Scanner (System. in); System. out. print
