public static void main(String args) {

    Scanner in = new Scanner(System.in);

    String word;

    String c;

    int x, count, count1;

    System.out.println("Please enter a word:");

    word=in.nextLine();

    x=word.length();

    count1=x;

    for(count=0;count<x;count++) {

        c=word.substring((count1)-1,count1);

        System.out.print(c);

        count1--;

    }`

}

Hi everyone, before I made this code that printed out a word backwards but now I am wondering how I can turn this into a palindrome checker but I am confused because the final product which is actually a word made out of a bunch of String c's put together, so I don't know how to compare it back to the original word that was entered. Help?

Start with a method signature and a value that you will return from it:

private boolean isPalindrome(String word1, String word2) {

  boolean isPalindrome = true; // let's initiate it to true

  // ...

  return isPalindrome;

} 

Then, you may use what you already have (I commented parts that are not needed:

x=word.length();

for(count=0;count<x;count++) {

    // c=word.substring((count1)-1,count1);

    // you can use word.charAt(count); instead

    // System.out.print(c);

    //count1--;

}`

Inside the loop, compare word1.charAt(count) with word2.charAt(count) and change isPalindrome to true if these don't match.

You may also want to check first if both strings have same length.

I see 2 possibilities to turn this in a palindrom-checker (i changed your existing code a little bit)

1. 
   

   compare the chars of the first half of the string to the second half, something like this:

   
   
   

   boolean isPalindrom = true;
   
   
   
   for (int i= 0; i < (word.length()-1)/2; i++) {
   
       if(word.charAt(i) != word.charAt(word.length()-1-i))
   
       {
   
           isPalindrom = false;
   
       }
   
   }
   
   
   
   System.out.println(word + " is a palindrom: " + isPalindrom);
   
   

   
   

or

2. 
   

   use your reversed String, save it to another String-variable and then check it it is equal to your word.
   Something like this:

   
   
   

   public static void main(String args) {
   
       Scanner in = new Scanner(System.in);
   
       String word;
   
   
   
       System.out.println("Please enter a word:");
   
       word = in.nextLine();
   
   
   
       String reverseString = "";
   
   
   
       for (int i = 0; i < word.length(); i++) {
   
           reverseString = reverseString + word.charAt(word.length()-1-i);;
   
       }
   
   
   
       System.out.println("original: " + word + ", reversed: " + reverseString);
   
   
   
       boolean isPalindrom = word.equals(reverseString);
   
   
   
       System.out.println(word + " is a palindrom: " + isPalindrom);
   
   }
