- What does this Method do? public static int myFun(int n) { if (n < 0) { } return 0; } else { } int currentNumber = n % 2 return currentNumber + myFun(n - 2); == 0 ? n n - 1; This method that takes an integer n and returns the sum of all odd positive integers less than or equal to n. This method that takes an integer n and returns the sum of all even positive integers less than or equal to n. This method that takes an integer n and returns the sum of all positive integers less than or equal to n. This method that takes an integer n and recursively find a value that is even or odd.Define a method printStateInfo() that takes two string parameters and outputs as follows, ending with a newline. The method should not return any value. Ex: If the input is MA Massachusetts, then the output is: ++ MA ++ is Massachusetts's state codejava 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
- 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)?"Please don;t change anything. put your code line 5. Java Write a static method named toCelsius that takes a single parameter fahrenheit as a double, converts Fahrenheit to Celsius, and returns the value as a double. The formula is 5 / 9 * (F - 32) = C1. write a static method that receive as parameter an array of type student and print the names of all students excepted to graduate. The student is expected to graduate if he/she in year 4 and GPA >2. 2. Write a java program that: a. Asks the user to enter the number of the Student, then the data of each Student and store then inside an array of type Student. b. Ask the user to read a value d of type double then displays the name of all the Student who have GPA greater than the value d. c. Call the above method and print the name of student who excepted to graduate.
- 1. Write a method called sumEven that returns the sum of even integers from 1 till a value num given as parameter. The header of the method is: public static int sumEven (int num) Using java code For example sumEven(10) returns the value 30 which is the sum of the integers 2, 4, 6, 8 and 10. 2. Write a main program that: a. Generates a random integer n between 20 and 100 inclusive. b. Displays the sum of even integers from 1 till n. Sample run The randomly generated number is: 34 The sum of even integers from 1 till 34 is 272What is the correct method signature of the below function/methods public double myTotal(float x, int y, double z){ return (X + Y + Z); } Select one: a. public double myTotal(float x, int y, double z) b. myTotal(float, int, double) c. myTotal(int, double , float) d. myTotal(float x, int y, double z) CLEAR MY CHOICE1.

- 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…Needs to be written in java: Write a program with a main() method that asks the user to input an integer array of 10 elements.Next, create three methods described below. From inside your main() method, call each of thethree methods described below and print out the results of the methods 2, 3, which return values.1. printReverse() - a method that receives an array of integers, then reverses the elements ofthe array and prints out all the elements from inside the method. Print all in one lineseparated by commas (see sample output below).2. getLargest() – a method that receives an array of integers, then returns the largest integervalue in the array. (print result from main())3. computeTwice()- a method that receives the previously reversed array of integers, thenreturns an array of integers which doubles the value of each number in the array (see thesample output below). (print result from main())Sample output:Enter a number:22Enter a number:34Enter a number:21Enter a number:35Enter a…Write a method that will receive 3 integers and return the largest integer. public static int findMax(int a, int b, int c) {
