6) A palindrome is a string of characters (a word, phrase, or sentence) that is the same regardless of whether you read it forward or backward-assuming that you ignore spaces, punctuation, and case. For example, Race car is a palindrome. Use stack ADT and write a java program that performs the palindrome operation. Turn in the source file otherwise - 4 points 1) True or false 3 points a) Stack allows random access b) The Stack from java.util package is an interface c) The Stack's peek() method removes the object at the top of this stack and returns that object as the value of this function. d) In stack it is possible to inherit methods from java.util.vector class e) In stack it is possible to inherit methods from java.lang.object class
