Dec 12, 2014 · try using StringBuilder.reverse. public String[] reverseString(String[] words) { String[] t = new String[words.length]; for (int i = 0; i < words.length; i++) { t[i]= new StringBuilder(words[i]).reverse().toString(); } return t; } Update

Mar 10, 2021 · To simplify the code, you can use an enhanced for loop instead of reversed for loop and swap the summands inside: String str = "hello world", reverse = ""; for (char ch : str.toCharArray()) reverse = ch + reverse; System.out.println(reverse); // dlrow olleh

You can iterate through an array in reverse order using For-Each loop like below: public class Main { public static void main(String[] args) { int arr[] = {2,3,1,4,7,6}; int i = arr.length-1; for(int e: arr){ // do something System.out.print(arr[i] + "\t"); i--; } } }

Mar 29, 2023 · Given a string str, your task is to reverse the order of the words in the given string. Note that str may contain leading or trailing dots(.) or multiple trailing dots(.) between two words. The returned string should only have a single dot(.) separating the words.

Sep 10, 2024 · In this text, we are able to discover how to reverse a string using a for loop and provide example program. We may even encompass code snippets with exact feedback to help you recognize the procedure.

Jan 7, 2025 · We can reverse each word of a string by the help of reverse(), split() and substring() methods. By using reverse() method of StringBuilder class, we can reverse given string. By the help of split("\\s") method, we can get all words in an array.

This Java 8 program demonstrates how to reverse each word in a string using streams. The map() method with StringBuilder makes the reversal of each word straightforward, and the collect() method allows for reassembling the reversed words into the final output.

Sep 15, 2017 · In this Program, we first split the given string into substrings using split () method. The substrings are stored in an String array words. The program then reverse each word of the substring using a reverse for loop. * a string in several strings based on the. * delimiter passed as an argument to it.

May 19, 2020 · Simply iterate the array, and replace each entry with its reverse. You can use a StringBuilder to reverse a String, calling StringBuilder.reverse. Like, public static void reverse(String[] array) { for (int i = 0; i < array.length; i++) { array[i] = new StringBuilder(array[i]).reverse().toString(); } } And then to test it
