Java Program Give comment to explain 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 help me! I have a lot of mini problems. I'm not sure how to start After #6, I have other problems. Those are : 7.) Write a method that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word Yes. If the sentence ends with a question mark and the input contains an odd number of characters, display the word No. If the sentence ends with an exclamation point (!), display the word Wow. In all other cases, display the words You always say followed by the input string enclosed in quotes. Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a legitimate sentence. Notes: This code requires a three-way selection statement and...

Java int[] numbers = {345, 632, 675, 157, 834, 294, 832};1. Write a method to find its highest value. 2. Write a method to find its lowest value. 3. Write a method to find its total value.

Here is the question: Create a program that contains a String that holds your favorite inspirational quote. Pass the quote to the calculateSpaces method and return the number of spaces to be displayed in the main method. Here is the code given: public class CountSpaces { public static void main(String[] args) { // write your code here } public static int calculateSpaces(String inString) { // write your code here } }

in this code, the integer on each line shows the line number that is not part of code: what is the signature of the method sum: ____ 1 public static int sum(int x, int y){ 2 int z = x +y; 3 return z; 4 } 5 public static void main(String[] args){ 6 ... 7 sum(a+2, b); 8 ... 9 }

3. Create a program for Smalltown Regional Airport Flights that accepts either an integer flight number or string airport code from the options in Figure 8-33. Pass the user’s entry to one of two overloaded GetFlightInfo() methods, and then display a returned string with all the flight details. The method version that accepts an integer looks up the airport code, name, and time of flight; the version that accepts a string description looks up the flight number, airport name, and time. The methods return an appropriate message if the flight is not found. Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming (MindTap Course List) (p. 347).

Need help with this java problem. Some Websites impose certain rules for passwords.Write a method that checks whether a string is a valid password. The method must takes a password as a parameter and return a boolean value. If the password is valid, returns true, otherwise, return false. Suppose the password rules are as follows:- A password must have at least eight characters.- A password must contain only letters and digits.- A password must contain at least two digits. Please make sure you write a comment line to document what your method does. Write a program that prompts the user to enter a password, then call the method that checks the password, and displays "Valid Password" if the rulesare followed, or Invalid Password otherwise. The main program must allow the user to check multiple passwords. It should ask the user "Do you want to continue checking anther password (y/n)?"

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 =...

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...

Write a program that asks the user to enter their name and a letter. The program should then use this information to output the string "<your name> guessed the letter <lowercase letter>", where <your name> is the name entered by the user and <lowercaseletter> is the lowercase form of the letter entered by the user.tip: make use of the method .lower() Example:Enter your name: Jane DoeGuess a letter: AJane Doe guessed the letter a
