Code 16-1 /** This class has a recursive method. */ public class EndlessRecursion { public static void message() { System.out.println("This is a recursive method."); message(); } } Code 16.2 /** This class has a recursive method message, which displays a message n times. */ public class Recursive { public static void messge (int n) { if (n>0) { System.out.println (" This is a recursive method."); message(n-1); } } } Task #1 Tracing Recursive Methods 1. Copy the file Recursion.java (see Code Listing 16.1) from the Student Files or as directed by your instructor. 2. Run the program to confirm that the generated answer is correct. Modify the factorial method in the following ways: a. Add these lines above the first if statement: int temp; System.out.println("Method call -- " + "calculating " + "Factorial of: " + n); Copyright © 2019 Pearson Education, Inc., Hoboken NJ b. Remove this line in the recursive section at the end of the method: return...

import java.util.Arrays; import java.util.Random; public class Board { /** * Construct a puzzle board by beginning with a solved board and then * making a number of random moves. That some of the possible moves * don't actually change what the board looks like. * * @param moves the number of moves to make when generating the board. */ public Board(int moves) { throw new RuntimeException("Not implemented"); } The board is 5 X 5. You can add classes and imports like rand.

Using the code in the image provided: Implement a method called summation which adds two integers and returns their sum. INPUT: The first line of input contains an integer a. The Second Line of input containes and integer b. OUTPUT: Print the result which is the sum of a and b.
