    Default Hey fellas whats wrong with my code? Im having problems here

    Write a Java program that takes as input one word W as a string (as args[0]), and checks if that word is a palindrome.

    Use the function charAt(index) to get the character at the index position in the string, and use
    N = W.length() to record the length of the string.

    Then, create a loop that will start with index = 0 and iterate to index < N / 2, and check if W.charAt(index) equals the character W.charAt(N-1-index).

    After the loop, if any two characters differ, print (W + “ is not a palindrome”); else, if all characters are
    the same, print (W + “ is a palindrome”).



    import java.util.Scanner;

    public class A23P1 {

    public static void main(String[] args) {

    Scanner input = new Scanner(System.in);
    System.out.println("Type a word");
    String W = input.nextLine();

    {
    int N = W.length();
    for (int i = 0; i < N / 2; i++)
    if (W.charAt(i) != W.charAt(N-1-i))
    return false;
    return false;
    }
    }

    You have open the { brace and return false; unnecessarily. Because you don't create any method

    you create the code like this..

    if (W.charAt(i) != W.charAt(N-1-i))
            {
               //print your statement here..
            }
            else{
                 //print your statement here..
            }

    You should ALWAYS use {}s with if statements and loops to prevent errors when the code is later modified.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    Copy the full text of the error messages you get and post it here.
    If you don't understand my answer, don't ignore it, ask a question.
