Write a Java method isPalindrome that takes a string as input and returns true if the string is a palindrome, and false otherwise. A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward. Ignore spaces, punctuation, and capitalization when determining if a string is a palindrome. Example: Input: "A man, a plan, a canal, Panama" Output: true (ignoring spaces, punctuation, and capitalization, the string reads the same forward and backward) Input: "hello" Output: false (not a palindrome)

Design a program with an algorithm that will take a string from the user and then decide if each character in that string is unique. For example, if you ask the user to enter a string and that user enters the world ‘hello’, the result of the algorithm implementedshould return ‘false’ or ‘not unique’. If the user enters a string such as the word ‘phone’ the program will return ‘true’ or ‘unique’ since every character in the word phone is unique and is not repeated. An example of this program follows: Output should show as :  enter a string rizma This string has all the unique characters  would u like to continue?(y for yes n for no) y Enter a string waali This string is not unique     Your code should work for all strings and essentially all characters, as many examples will be tested.

Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows. Ex: If the input is: apples 5 shoes 2 quit 0 the output is: Eating 5 apples a day keeps the doctor away. Eating 2 shoes a day keeps the doctor away.
