Create array with reversed words from user string

Anne Bailly :

I am creating a program in which a user enters a string of words (Ex: I love you), and the program returns an array of the words in the string spelled backwards (Ex: I evol ouy). However, I cannot get my code to properly compile, and tried debugging, but cannot see where the problem is.

I tried to look for similar problems here on Slack, but the problems are found were concerned with rearranging words from a string, (ex: you I love), and I cannot find a problem similar to mine, involving turning string into an Array and then manipulating the array.

    Scanner sc = new Scanner(System.in);
    System.out.println("Enter a string to see it in reverse: ");
    String userEntry = sc.nextLine();
    char[] entryToChar = userEntry.toCharArray();
    System.out.println(Arrays.toString(entryToChar));
    String[] splitInput = userEntry.split(" "); 
    String reverseWord = "";
    int temp;
    String[] reverseString = new String[splitInput.length]; 

    for (int i = 0; i < splitInput.length; i++) 
    {
        String word = splitInput[i];            


        for (int j = word.length()-1; j >= 0; j--) 
        {
            reverseWord = reverseWord + word.charAt(j);
        }            

        for (int k = 0; k < splitInput.length; k++) {
                temp = splitInput[i];
                splitInput[i] = reverseWord[j];
                reverseWord[j] = temp;

                }

     }  System.out.println("Your sttring with words spelled backwards is " + reverseWord[j]);

I am avoiding using the 'StringBuilder' method as I have not yet studied it, and trying to see if I can get the new string using swapping, as in the code below:

temp = splitInput[i];
splitInput[i] = reverseWord[j];
reverseWord[j] = temp;

import java.util.Arrays;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        String word, reverseWord;
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter a string to see it in reverse: ");
        String userEntry = sc.nextLine();

userEntry: I love you

        String[] splitInput = userEntry.split(" ");

splitInput: [I, love, you]

        for (int i = 0; i < splitInput.length; i++)
        {
            word = splitInput[i];
            reverseWord = "";
            for (int j = word.length()-1; j >= 0; j--)
            {
                reverseWord = reverseWord + word.charAt(j);
            }
            splitInput[i] = reverseWord;
        }

splitInput: [I, evol, uoy]

        System.out.println("Your string with words spelled backwards is: " + String.join(" ", splitInput));
    }
}

Your string with words spelled backwards is: I evol uoy
