Palindrome

A palindrome is a string that is the same (except for the space between words) whether you read it forwards or backwards (e.g. "otto", "a toyota" or "ed is on no side").

You can check if a string is a palindrome by

• creating a new string as the original one reversed (use a loop that runs through the string, gets each character using charAt() and adds this character to the new string)
  
• removing all spaces (use a loop and as long as there is a space in the string, you set the string to be the substring before the space + the substring after the space)
  
• running through the strings and compare each character in one string with the character at same index in the other string (again using charAt()). If the loop finds a character that is not the same in both strings you immidately return false. If the loop finished without any character beeing different you return true.

Question 1
Create a worker class, Palindrome, with a string-variable str (with set- and get- methods) and a method, isPalindrome(), that checks if str is a palindrome and returns the boolean result.

Create an application class, PalindromeApp, that creates a Palindrome object and then tests different strings (sets the value in the object to be the string you want to test and then perform the test using isPalindrome())

A good way to check if your program works is to write both strings (with all spaces removed) to the screen - it's easy to spot any difference
