Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content:

- T/F A Java main method uses the parameter (String[ ] variable) so that a user can run the program and supply“command-line” parameters. Since the parameter is a String array, however, the user does not have to supply anyparameters.True or False The versions of an overloaded method are distinguished by the number, type, and order of their parameters.Value-returning methods must pass parameters. -True or -False
- Language:Java - Requests two double values from the user and stores them in local variables in main() - Create a method which takes these two values as parameters- The method will use Math library functions to: o Print the square root of the 1st parametero Print the log of the 2nd parametero Print the value of the 1st parameter raised to the power of the 2nd parameterJAVA Question 2: For two integers m and n, their GCD (Greatest Common Divisor) can be computed by a recursive method. Write a recursive method gcd(m,n) to find their Greatest Common Divisor. Method body: If m is 0, the method returns n. If n is 0, the method returns m. If neither is 0, the method can recursively calculate the Greatest Common Divisor with two smaller parameters: One is n, the second one is m mod n (or m % n). The recursive method cannot have loops. Note: although there are other approaches to calculate Greatest Common Divisor, please follow the instructions in this question, otherwise you will not get the credit. main method: Prompt and read in two numbers to find the greatest common divisor. Call the gcd method with the two numbers as its argument. Print the result to the monitor. Example program run: Enter m: 12 Enter n: 28 GCD(12,28) = 4 And here is what I have so far, package CSCI1302;import java.util.*;public class RecursionDemo { public static void…Java: Class: SortedNumbers Write a method for the method header below and provide a (main) program to test it: boolean sorted(double x, double y, double z), returning true if the arguments are sorted, with the smallest one coming first Remember to include the Javadoc comment for the method.

Your program will draw a board with 64 squares using the traditional layout, next ask the user to choose a move, and then, depending on the user's choice, redraw the board with the selected chess piece and its valid moves. Please see the examples of valid moves of chess pieces and the traditional chess board layout below: At the beginning, your program should draw an empty chess board and prompt the user to enter a move: Welcome to the Chess Game! a b c d e f g h +---+---+---+---+---+---+---+---+8| | | | | | | | |8 +---+---+---+---+---+---+---+---+7| | | | | | | | |7 +---+---+---+---+---+---+---+---+6| | | | | |…In Java code do the following:Write a method that accepts a String as an argument. The method should use recursion to display each individual character in the String:
- Create a class Recursion. It will have two static methods: removeX and countSubstring and write each function recursively. Recursion class removeX The removeX function will take a String as a parameter. It will return a new String that is the same as the original String, but with all “x” characters removed. This method will be case insensitive. countSubstring The countSubstring function will take two strings as parameters and will return an integer that is the count of how many times the substring (the second parameter) appears in the first string without overlapping with itself. This method will be case insensitive. For example: countSubstring(“catwoman loves cats”, “cat”) would return 2 countSubstring(“aaa nice”, “aa”) would return 1 because “aa” only appears once without overlapping itself. Create a Main class to test and run your Recursion class.NOTE: JAVA language Write a program that asks the user for his first name and then prints it using a function/method called printName(). We do not expect the first name to exceed 20 letters. Then the program should print the name with a space between each character. Example: if the first name is Maryam, the :program will print Maryam -1 Maryam -2JAVA Problem description:You are to write a program called Seasons that prompts the user for a month and day and displays the season in which that date occurs. For reference, we will use the following date cutoffs for the various seasons: Winter December 21 – March 19 Spring March 20th – June 20th Summer June 21st – September 20th Fall September 21st – December 20th Data Validation For this program, you'll write a specific method to perform data validation based on the month and day entered. More specifically: Month – the month entered must be a valid month of the year (January – December). Day – the day entered must be a valid day for that month: January, March, May, July, August, October, December have 1-31 days. April, June, September, November have 1-30 days. February has 1-28 days (do not worry about leap years) Required program decomposition String getMonth(Scanner console) This method is called from the main method and should prompt for the month as a string…
