java program give comments for the code please.   Write a program that calls these two methods as described below A void method that ask user to input an integer to be a parameter and prints following pattern. For example, the user entered 5 as input, the pattern will be:   5 4 3 2 1 5 4 3 2 5 4 3 5 4 5       b. A void method takes Sting as a parameter. Then print out all the vowels in the string. Example given below: Please enter a String. Christopher Vowel in the String:ioe

In this assignment you will demonstrate your knowledge of debugging by fixing the errors you find in the program below. Fix the code, and paste it in this document, along with the list of the problems you fixed.This example allows the user to display the string for the day of the week. For example, if the user passed the integer 1, the method will return the string Sunday. If the user passed the integer 2, the method will return Monday. This code has both syntax errors and logic errors. Hint: There are two logic errors to find and fix (in addition to the syntax errors).Inport daysAndDates.DaysOfWeek;public class TestDaysOfWeek {public static void main(String[] args) {System.out.println("Days Of week: ");for (int i = 0;i < 8;i++) {System.out.println("Number: " + i + "\tDay Of Week: " + DaysOfWeek.DayOfWeekStr(i) )}}}package daysAndDatespublic class DaysOfWeek {public static String DayOfWeekStr(int NumberOfDay) {String dayStr = ""switch (NumberOfDay) {case 1:dayStr =…

A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6.   Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the method in a complete program.   Tip: Recall that the % operator divides one number by another, and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2.   can you please write it in java.util.scanner form and can you make it so i can copy and past it  thank you in advance

Java language Write a method to find the number of hours, minutes, and seconds and then display it as shown below. The method receives the total number of seconds as parameters. Output is Hour[totalSeconds=3750, nb_Hours=1, nb_Minutes=2, nb_Seconds=30]

Write a program called LoopMethod (main method) that contains a method called printNums (method name) that prints the numbers from a specified start to end value. a) The main method will do the following: • asks the user for start and end number (int type). • calls the printNums methodb) The printNums method will do the following: • receives start and end number (parameters)• prints from the start to the end number using a loop Sample Run: Input start number: 3Input end number: 93 4 5 6 7 8 9Input start number: 9Input end number: 219 10 11 12 13 14 15 16 17 18 19 20 21

Q3. Create two methods: one that will reverse the order of the digits in an integer and a second determines if a number is a palindrome (i.e. reads the same front to back) using the following method headers. // Method 1: Takes in an integer and reverses it, e.g., reverse(456) returns 654 public static int reverse(int number) // Method 2: Takes in an integer and returns true if it is a palindrome. Use the reverse method you just wrote to implement this method. public static boolean isPalindrome(int number) Create a test program that asks the user to input an integer and provides feedback on whether the integer is a palindrome or not. Hint: To find the reverse number, use one of the following approaches: • Modify your numerical inputs to a string, then use a for loop to reverse the characters with string concatenation and the charAt() method. Retrieve individual digits and combine them in reverse order using the / and % operators, using ten as a divisor. Combine the digits with either…

The following snippet shows a Java method that takes a football score (for teams A and B) and reports the current match status ("A is winning", "B is winning" or "It's a draw!"). The code contains one error. On line 3, the condition checks whether the value of "b" is greater than zero, rather than checking if it is greater than "a". 01: String formatScore (int a, int b) { 02: 03: if (a > b) return String.format("A is winning!"); if (b> 0) return String.format("B is winning!"); return String.format ("It is a draw!"); 04: 05: } (i) Use equivalence class partitioning to design a set of tests for the method that covers all possible classes of inputs. Give a table with input values (for a and b) and the expected result. Do your tests find the error in the code? (ii) (Consider the tests designed in (i). Is it possible to give a table that answers the question (i) correctly, but does not actually reveal the error in the code? Explain your answer. (iii) Now we want to use property-based…
