In java without Arrays and only using String Methods (Don't use Stringbuilder or Stringbuffer) // Question 18a: Write the method below that tests // whether a word is a palindrome (the same when read // forward or back, such as "madam"). Test isPalindrome // using the appropriately modified StringTest program   public static boolean isPalindrome(String dateStr) {   }   // Question 18b: Upgrade isPalindrome so that it can handle // any phrase (as in, "Madam, I'm Adam"). Copy the logic of // isPalindrome into isPalindromePhrase below to start. // // In testing for a palindrome, disregard all spaces, punctuation // marks, apostrophes, and other non-alphanumeric characters // and consider upper and lower case characters the same. Do not // count an empty string as a palindrome. // Hint: recall that the character class has static methods: // - boolean isLetterOrDigit(ch) // - char toUpperCase(ch)   public static boolean isPalindromePhrase(String dateStr) {   }

Please include a gui for the encryption and decryption java code. Example of the gui in the photos Java encryption and decryption code below import java.util.*; public class Main { //Inputs a one character string and returns True if the character is a letter (i.e. a to z or A to Z). Returns false if it is not. A function to check that the password or encryption key is valid. public static boolean isALetter(char letter){ if( (letter >= 'a' && letter = 'A' && letter =-32767 && encryptKey

Hello. I can't get this Java code to work. It takes a series of sentences as a single string. The function capitalizes the first letter of every sentence What am I doing wrong?   /*Programming ChallengesChapter 9 #3 Pg. 608 Title: Sentencee CapitallizerWrite a method that accepts a String object as an argument and returns a copy of the stringwith the first character of each sentence capitalized. For instance, if the argument is “hello.my name is Joe. what is your name?” the method should return the string “Hello. My nameis Joe. What is your name?” Demonstrate the method in a program that asks the user toinput a string and then passes it to the method. The modified string should be displayed onthe screen.*/ import javax.swing.JOptionPane; public class SentenceCapitalizer{public static void main(String[] args){String input;input = JOptionPane.showInputDialog("Enter a string.");JOptionPane.showMessageDialog(null, sentenceCap(input));System.exit(0);} public static String sentenceCap(String…
