- Write code for the following Java methods. Test your code. Take screenshots. Submit yourscreenshots with your code files.1). Write a Java method that receives an integer number, converts, and returns itscorresponding ASCII character ('a' to 'z' or 'A' to 'Z'). If the integer is out of range, the methodshould display an error message;2). Write a Java method that receives three integer numbers, and returns the largest integer;3). Write a Java method which receives a positive integer number, and displays all primenumbers from 1 to the integer number it receives. You should research on the Internet regardingwhat a prime number is. If the integer is negative (or zero?), the method should display an errormessage;4). Write a Java method that receives a positive integer number, and finds out if the integernumber corresponds to a leap year. You should research on the Internet regarding what a leapyear is. If the integer is negative, the method should display an error message;5). Test all…Write a Java program that randomly generates a three-digit lottery number and prompts the user to enter a three-digit number. Each digit in the number is in the range between 0 to 9 with both 0 and 9 possible numbers. Write a method named getPrize() to determine which prize the user wins following the rules shown below. The method getPrize() should return an integer representing which prize was won such as 1 for first, 2 for second, etc. It should return -1 if no prize was won.For the Java code below, you will demonstrate the ability to use and call multiple methods in your program. Using the code below, create the following methods: 1. A method that converts the temperature from Fahrenheit to Celsius. The method should be passed a parameter - Fahrenheit and should return a result - Celsius. 2. A method to output the results of your temperature conversion. The method should be passed 2 parameters - temperature in Fahrenheit and the temperature in Celsius. Finally, place an edit in your code to ensure that the user only enters a numeric value. Your output should appear as follows: Enter the Fahrenheit temperature you want to convert: 212 This converts to 100 Celsius Do you want to convert another temperature – Y or N? Y Enter the Fahrenheit temperature you want to convert: 100 This converts to 37.8 Celsius Do you want to convert another temperature – Y or N? N The program has ended import java.text.DecimalFormat;import java.util.Scanner; public class…
- A Java program has been started for you. The goal of the program is to prompt the user to enter a credit card number and then display whether the card is valid/invalid. Several method headers have already been defined in the code. Your task is to complete the body of each of these methods (6 in total) so that the program accomplishes the stated goal above. Below I have started the code for you as practice and I even included hints as comments to help you out. import java.util.Scanner; public class CreditCard {public static void main(String[] args) {Scanner input = new Scanner(System.in);System.out.print("Enter a credit card number: ");long number = input.nextLong(); if (isValid(number))System.out.println("valid");elseSystem.out.println("invalid");} /** Return true if the card number is validWhat makes a card number valid?1. 13-16 digits2.

You must do the following requirements: Create three methods: First method to accept and print your first, last name, and GPA. Second method to accept and print your grades of three courses (type: int) Third method to overload the second method (types: double). The method must print your grades. Call the three methods you created above in your main method. Create a method without parameters that would return only your GPA. The method should be named with your last name followed by GPA (e.g., AlwalledGPA()). Declare a double variable that holds the returned value of the last method you created. Print the value of your GPA variable. I attached Typical run of the programIn Java, please don't modify only fill in the code where it says "/* Define your methods here. */" and"/* Type your code here. */" everything need to stay the same in the picture or do not answer it.

- Create two methods in java the first: that takes a value from the user and tell whether it is null or not. Declared as: boolean isZero (float a) the second: Create a method delta() that takes three values, a, b and c, from the user which are the coefficients of a quadratic equation and returns the value of the delta, which is given by b 2 - 4ac (with a screenshot of the code please)This question is based on Java Programming language. The below java code, displays the calendar for a given month of the year. The program prompts the user to enter the year and the month, then displays the entire calendar for the month. Can you explain the code and its functions ? you can explain in paragraph or point form. //Java code // Header file to take user input import java.util.Scanner; //main class public class Main { //method is used to check days for the month public static int dayOfMonth(int mon, int day, int yr) { int y = yr - (14 - mon) / 12; int x = y + y/4 - y/100 + y/400; int m = mon + 12 * ((14 - mon) / 12) - 2; int d = (day + x + (31*m)/12) % 7; return d; //return day of month } //function is used to check whether the year is leap year or not public static boolean leapYear(int yr) { //check using if-else if ((yr % 4 == 0) && (yr % 100 != 0)) return true; //return true if not a leapYear if (yr % 400 == 0) return true; //return true if not a leapYear…MethodsJava Write the appropriate method headings using the provided method name for the following processes:1.) Given the radius of a circle, print the area of a circle - printArea. 2.) Accept an integer, compute for the square of the number and return the String equivalent of the square of the number - makeString 3.) Calculate and return the sum of two decimal numbers - getSum. 4.) Given a student’s name and three test scores (of type int), print the student’s name and average test score - printStudentDetails. 5) Compute and return the average speed of a car, given the distance traveled (as type double) and traveling time (in hours and minutes, both of type int) - getAverageSpeed.
- Complete the Java static method given below called MtoK that converts miles to kilometers. The method has one parameter called M which is the miles traveled and it returns the converted kilometers. Note that 1 mile is equal to 1.6 kilometer. The method heard is given below: public static double MtoC(double M)1. Write a Java program that will ask the a user a number between 1 to 7. 2. Print out the equivalent day of the week for that number. Starting 1 for Sunday, 2 for Monday and etc. 3. Use at least 1 user-defined method aside from your main method in writing a code for this problemWrite a Java class called Power. This class defines a method called power() which takes as parameters a double called base as well as an int called exponent, and returns a double representing the value of base raised to the power exponent. The exponent is a non-negative integer value, and that base and exponent are not both 0. You MUST write the computation yourself; in other words, you MUST NOT use the Math.pow() method. Repeat the operation often.
