JAVA Program    modify this program below: so it does not use a while loop. 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

Java - Help Please How do I output this statement as a horizontal statement with a newline? Everytime I use System.out.println, it makes the entire output vertical instead of horizontal. Program below. import java.util.Scanner; public class LabProgram {   public static void main(String[] args) {      int x;      int y;      Scanner scan = new Scanner(System.in);            x = scan.nextInt();      y = scan.nextInt();            if(y >= x){      for(int i=x; i<=y; i = i + 5)      {      System.out.print(i+ " "); (The problem line)         }      }      else{      System.out.print("Second integer can't be less than the first.");      }   }}

Complete the convert() method that casts the parameter from a double to an integer and returns the result.Note that the main() method prints out the returned value of the convert() method. Ex: If the double value is 19.9, then the output is: 19 Ex: If the double value is 3.1, then the output is: 3 code: public class LabProgram {      public static int convert(double d){      /* Type your code here */               }   public static void main(String[] args) {      System.out.println(convert(19.9));      System.out.println(convert(3.1));   }}

Examine this code and determine what happens when it is run: 1 public class Test { int x; 2 3 public Test(String t){ System.out.println("Test"); } public static void main(String[] args) { Test test = new Test ("boo"); System.out.println(test.x); } 4 5 6 7 8 10 } The program has a compile error because Test does not have a default constructor. The program has a compile error because System.out.println method cannot be invoked from the constructor. ) The program runs successfully and prints out: Test O The program has a compile error because you cannot create an object from the class that defines the object.

Exercise 1Write a Java method random that generates and returns a random number between 14 and 59(using SecureRandom). Test your method several times using a main function

using System; class Program { publicstaticvoid Main(string[] args) { int number = 1; while (number <= 88) { Console.WriteLine(number); number = number + 2; } Random r = new Random();   int randNo= r.Next(1,88); Console.WriteLine("Random Number between 1 and 88 is "+randNo); } }   how would this program be modified to choose three random numbers instead of just one number between 1-88?
