Q3. Write a test class: TestStackOfPalindromes that: 1. Create a StackOfPalindromes object using the class's no-arg constructor 2. Use this object to push these words to the stack: Anna, Civic2021, Computer, Mad?am, Level5, M-am, Java. 3. Print the stack elements using the pop method from the created object, and as displayed in the sample below. Q1. 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 stack's size. 3. An integer constant DEFAULT_CAPACITY for the stack's 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. Q3. Write a test class: TestStackOfPalindromes that: 1.
