Q:

Java Palindrome (Boolean Method) with iterative solution (while loop)

Why doesn't my palindrome program work correctly? It always returns false, and I can't tell why.
Here is my code:
public static boolean isPalindromIterative(String string) {
    int a = 0;
    int b = string.length() - 1;        
    while (b > a) {
        if (a != b) {            
            return false;
        }
        a++;
        b--;        
    }
    return true;
}

A:

You are comparing values of a and b which aren't the same when you start comparing and hence you get false from your method. 
In your if condition, Change it to be string.charAt(a) != string.chatAt(b)
