I have two strings. The first is normal string, the second I want to be a reversed string like first one, but in the console I didn't get the look of like first one listed by commas. How can I fix that ?

Normal string -

Revered string -

window.onload = function(){inputBox =document.getElementById("myText");btn = document.getElementById('sub');btn.addEventListener("click",function(event){event.preventDefault();    findPalindromes(inputBox.value);   });    str = inputBox.value;    function findPalindromes(str) {        var words = str.split(" ");            for (var i = 0; i < words.length - 1; i++) {                words[i] += " ";            }        console.log(words);        var newString = "";            for (var i = words.length - 1; i >= 0; i--) {                newString += words[i];            }        console.log(newString);     }} 

I am trying to write my own string reverse algorithm (I know this already exists in java but I am doing this for education). The code below is what I have so far. It outputs only half the string reversed. I have done some debugging and the reason is that it is changing stringChars2 at the same time as stringChars but I have no idea why that is happening as I am only trying to change stringChars. All help greatly appreciated.

EDIT my question was not "how to reverse a string" which has been asked before... but why my objects where changing without instruction, the answer below completely explains the problem.

public static void main(String[] args) {    //declare variables    Scanner input = new Scanner(System.in);    String myString = "";    int length = 0, index = 0, index2 = 0;    //get input string    System.out.print("Enter the string you want to reverse: ");    myString = input.next();    //find length of string    length = myString.length()-1;    index2 = length;    //convert to array    char[] stringChars = myString.toCharArray();    char[] stringChars2 = stringChars;    //loop through and reverse order    while (index<length) {        stringChars[index] = stringChars2[index2];        index++;        index2--;    }    //convert back to string    String newString = new String(stringChars);    //output result    System.out.println(newString);    //close resources    input.close();}

I am trying to reverse a string WITHOUT using StringBuilder. I have written the below code but it is giving an error as soon as it hits the loop. The error is

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 16at lectures.ReverseString.main(ReverseString.java:38)

if anyone could tell me why that would be great. FYI I realize this code is not efficient or elegant but I want to know why it isn't working for education.

 public static void main(String[] args) {    //declare variables    Scanner input = new Scanner(System.in);    String myString = "";    int length = 0, index = 0, index2 = 0;    //get input string    System.out.print("Enter the string you want to reverse: ");    myString = input.nextLine();    //find length of string    length = myString.length();    index2 = length;    //convert to array    char[] stringChars = myString.toCharArray();    char[] stringChars2 = stringChars;    //loop through and reverse order    while (index<length) {        stringChars2[index] = stringChars[index2];        index++;        index2--;    }    //convert back to string    String newString = new String(stringChars2);    //output result    System.out.println(newString);    //close resources    input.close();}

import static javax.swing.JOptionPane.*;public class ClassPractice {    public static void main(String args[]) {        String original, reverse = "";        original = showInputDialog("Enter a string to reverse");        int length = original.length();        int size = length - 1;        for (int i = size; i >= 0; i--) {            reverse = reverse + original.charAt(i);        }        showMessageDialog(null, "Reverse of entered string is: " + reverse);    }}

Write a program that translates a text to Fake Latin and back. English is translated to Fake Latin by taking the first letter of every word, moving it to the end of the word and adding ‘ay’ to each word.As an example, if your program reads from the keyboard the string “The quick brown fox” then it should print on the screen the following text: “Hetay uickqay rownbay oxfay”.You should also implement the reverse of this, reading "Iay ikelay rogrammingpay" should print on the screen "I like programming".

public class fakelatin {      public static void main(String[] args)  {     Scanner pig = new Scanner(System.in);     String word;  original word     String latin = "";       char first;     boolean cap = false;     String line;     System.out.print("enter line to translate: "); //enter the line to translate     line = pig.nextLine();    pig = new Scanner(line);    // loop through all the words in the line     while (pig.hasNext())  // is there another word?     {        word = pig.next();        first = word.charAt(0);        if ('A' <= first && first <= 'Z')  // first is capital letter        {           first = Character.toLowerCase(first);           cap = true;        }        else            cap = false;     // test if first letter is a vowel        if (first=='a' || first=='e' || first=='i' || first=='o' || first=='u')           latin = word + "ay";       else        {              if (cap)           {              latin = "" + Character.toUpperCase(word.charAt(1));  // char to String conversion              latin = latin + word.substring(2) + first + "ay";           }           else                latin = word.substring(1) + first + "ay";        }        System.out.print(latin + " ");     }   }}

i have got the output as iay ikelay rogrammingpay as i want it

import java.util.Scanner;public class fakelatin2 {    public static void main(String[] args)  {     Scanner pig = new Scanner(System.in);     String word; // original word     String latin = "";  // pig latin translation, init to empty string     char first,last;     boolean cap = false;     String line;     System.out.print("enter line to translate: ");     line = pig.nextLine();     pig = new Scanner(line);     // loop through all the words in the line     while (pig.hasNext())  // is there another word?     {        word = pig.next();        first = word.charAt(0);        last=word.charAt(word.length()-1);        if ('A' <= first && first <= 'Z')  // first is capital letter        {           first = Character.toLowerCase(first);           cap = true;        }        else            cap = false;           latin = word.replaceAll("ay", "");        if(cap)        {            latin = "" + Character.toUpperCase(word.charAt(1));         latin=latin+word.substring(word.length()-1);        }        System.out.print(latin + " ");     }   }}

i am getting an output as "i ikel rogrammingp" but not able to get "i like programming"back
