Q 1. Write java code for a class called StackOfPalindromes, which is used to check an array of words, determine the palindromes among these words, and save the palindromes in a stack. The class contains:

1. A String array named words for the words to be checked.

2. An integer data field named size for the stacks size.

3. An integer constant DEFAULT_CAPACITY for the stacks default capacity, which is 5.

4. A no-arg constructor that invokes an arg-constructor, which creates a stack with the specified capacity.

5. A method named push() that takes a word, filters it from any non-alphabetic characters (i.e. remove numbers and other symbols), checks if it is a palindrome, and pushes it to the stack only if its palindrome.

6. A method named pop() that returns the word on top of the stack and removes it from the stack.
