JAVA Program    modify this program below: take out  while (true) { and use something else. Instead it uses recursive method that doesn't copy the string over and over again.    import java.util.Scanner; public class PalindromeChecker {     public static void main(String[] args) {         Scanner scanner = new Scanner(System.in);         while (true) {             System.out.print("Please enter a string to test for palindrome or type QUIT to exit:\n");             String input = scanner.nextLine().toLowerCase();             if (input.equals("quit")) {                 break;             }             if (isPalindrome(input)) {                 System.out.println("The input is a palindrome.");             } else {                 System.out.println("The input is not a palindrome.");             }         }     }     private static boolean isPalindrome(String str) {         str = str.replaceAll("[^a-zA-Z0-9]", "");         int left = 0;         int right = str.length() - 1;         while (left < right) {             if (str.charAt(left) != str.charAt(right)) {                 return false;             }             left++;             right--;         }         return true;     } }   Chapter 16. PC #5. Palindrome Detector (page 1073) A palindrome is any word, phrase, or sentence that reads the same forward and backward. Here are some well-known palindromes: Able was I, ere I saw Elba A man, a plan, a canal, Panama Desserts, I stressed Kayak Write a boolean method that uses recursion to determine whether a String argument is a palindrome. The method should return true if the argument reads the same forward and backward. Demonstrate the method in a program. The program should ask the user to enter a string, which is checked for palindrome property. The program displays whether the given input is a palindrome or not, then prompts the user to enter another string. If the user enters QUIT (case insensitive, then exit the program).     Test Case 1         Please enter a string to test for palindrome or type QUIT to exit:\n Desserts, I stressedENTER The input is a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n KayakENTER The input is a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n quitENTER   Test Case 2         Please enter a string to test for palindrome or type QUIT to exit:\n dadENTER The input is a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n quitENTER   Test Case 3         Please enter a string to test for palindrome or type QUIT to exit:\n momENTER The input is a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n QuitENTER   Test Case 4         Please enter a string to test for palindrome or type QUIT to exit:\n helloENTER The input is not a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n quiTENTER           Please enter a string to test for palindrome or type QUIT to exit:\n b,a,dENTER The input is not a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n quitENTER   Test Case 6         Please enter a string to test for palindrome or type QUIT to exit:\n Able was I, ere I saw ElbaENTER The input is a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n quitENTER   Test Case 7   Passed!     Please enter a string to test for palindrome or type QUIT to exit:\n A man, a plan, a canal, PanamaENTER The input is a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n quitENTER   Test Case 8         Please enter a string to test for palindrome or type QUIT to exit:\n @abENTER The input is not a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n ab@ENTER The input is not a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n @aaENTER The input is a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n aa@ENTER The input is a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n quitENTER   Test Case 9         Please enter a string to test for palindrome or type QUIT to exit:\n abbaENTER The input is a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n abcaENTER The input is not a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n aabcaaENTER The input is not a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n abaceedabaENTER The input is not a palindrome.\n Please enter a string to test for palindrome or type QUIT to exit:\n quitENTER

Besides main() this program has one method that computes the amount of raise and the new salary for an employee.  The current salary and a performance rating (a String: "Excellent", "Good" or "Poor") are input. import java.util.Scanner; public class Salary {    public static void main (String[] args)    {        Declare variables       Prompt for and read current salary and rating For an excellent rating compute raise as 0.06 of current salary For a good rating compute raise as 0.04 of current salary For a poor rating compute raise as 0.015 of current salary You can use abc.equals(“xyz”) to verify the rating read For an invalid rating display an appropriate message and display the  salary without change; otherwise, compute and print new salary and raise amount main() must display the message    } }   Note:- Please type and execute this java program and also need an output for this java program as soon as possible.

Part 1 - Given the following code, the output is __. class Sample{  public static void main (String[] args){  try{  System.out.println(5/0);}catch(ArithmeticException e){  System.out.print("Divide by zero????");}finally{  System.out.println("5/0");  } }} A. Divide by zero????B. 5/0C. Divide by zero????5/0D. 5/0Divide by zero????E. "5/0" Part 2 - Given the following code, the output is __. try{  Integer number = new Integer("1");   System.out.println("An Integer instance.");}catch (Exception e){  System.out.println("An Exception.");} A. An Integer instance.B. An Exception.C. 1D. Error: ExceptionE. None of the options
