    Default How to do the main ?

    Write a program that has an array of 5 Strings, and determines which ones are
    palindromes (letter-case does not matter)
    The main should only initialize the array, and
    print the palindrome words found. You can break your problem into smaller pieces
    dealt with in separate methods. For example you might need a method that determines
    whether a String is a palindrome or not

    public class Palindrome
    {
      public static void main(String [] args) {
         String[] s = new String[5];
     
        }
        public static String Reverse(String x) {
            String hold = "";
            char [] c = x.toCharArray();
            for (int i = c.length-1; i>0; i--)
            hold = hold +c[i];
            return hold;
        }
     
     
     
        public static boolean pallindromCheck(String n) {
            String x=Reverse(n);
            if (x==n)
                return true;
            else
                return false;
            }
    }


    thanks...

    Hello sarrrry92!
    You are initializing your array but the values it keeps are the default ones (null). You should better fill it with some Strings, some of them palindromes
    For example:
    String[] s = {"anna", " dien", "omnnmo"};
    Then you can loop through your array and call the pallindromCheck(String n) method.
    And something else i noticed:
    if (x==n)
    You should use the String's equals() method instead of the == operator when comparing Strings.
    Hope it helps.
