JAVA Program Modify this program so it passes all the Test cases and it should not use a while loop. Instead try to write a recursive method that doesn't copy the string over and over again. I have provided the failed test cases. import java.util.Scanner; // creating a class class Main { // creating a method that determines whether the given string is palindrome or not public static boolean isPalindrome(String str) { // if length of the given string is 0 or 1 if (str.length() <= 1) { return true; } // otherwise else if (str.charAt(0) == str.charAt(str.length() - 1)) { return isPalindrome(str.substring(1, str.length() - 1)); } else { return false; } } // Driver code public static void main(String[] args) { // scanner object used to take user inputs Scanner sc = new Scanner(System.in); String str; while(true){ System.out.println("Please enter a string to test for palindrome or type QUIT to exit:"); // taking a string and convert it into lower case str = sc.nextLine().toLowerCase(); if (str.equals("quit")) { break; } // otherwise else{ // if method returns true if (isPalindrome(str)) { System.out.println("The input is a palindrome."); } // otherwise else { System.out.println("The input is not a palindrome."); } } } } } 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).

Modify this JAVA Program Take out while (true) { from the program and use something else. Instead use a 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) {...

I need help with this Java problem to output like in this image below (Not the one highlighted in yellow): Number pattern Write a recursive method called printNumPattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until a negative value is reached, and then continually add the second integer until the first integer is again reached. For this lab, do not end output with a newline. Ex. If the input is: 12 3 the output is: 12 9 6 3 0 -3 0 3 6 9 12 This Java code that I need help with: import java.util.Scanner; public class NumberPattern { public static void printNumPattern(int x, int y) { System.out.print(x+" "); int n=x-y; if (n < 0) { System.out.print(n+" "); System.out.print(x+" "); while(n != 12){ n=x+y; x=x+y; System.out.print(n+" "); } return;...

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."); } }}

Stuck on Java again. Have to complete this using for-loops but everything I've tried has just given me errors. Any help would be appreciated!

Write code that prints: countNum ... 21 Print a newline after each number. Ex: If the input is: 3 the output is: 3 2 1 1 import java.util.Scanner; 3 public class ForLoops { UAWN HOUх и блашин 2 ST 4 5 6 7 8 9 10 11 12 13 14 15 } public static void main (String [] args) { int countNum; int i; Scanner input = new Scanner(System.in); input.nextInt(); countNum = for * Your code goes here *) { System.out.println(i); } }

Write the code in java and understand what the question says and give me the code and don't copy or plagiarize please

Write a Non tail recursion and a tail recursion method in Java with a test class that does the following: The factorial of a positive integer n —which we denote as n!—is the product of n and the factorial of n 1. The factorial of 0 is 1. Write two different recursive methods in Java that each return the factorial of n. Please and Thank you

Write a recursive method called drawTriangle() that outputs lines of '*' to form an upside down isosceles triangle. Method drawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the last line for correct formatting. Hint: The number of '*' decreases by 2 for every line drawn. Ex: If the input of the program is: 3 the method drawTriangle() outputs: *** * Ex: If the input of the program is: 19 the method drawTriangle() outputs: ******************* ***************** *************** ************* *********** ********* ******* ***** *** * Note: No space is output before the first '*' on the first line when the base length is 19.

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.
