iLAB OVERVIEW;Scenario and Summary;In this lab you will create programs that use control structures and user-defined methods.;Deliverables;Program files for each of the following three programs.;Largest;Palindrome;Diamond;At the beginning of ALL your programs, put a comment box that includes the program name, your name, and a brief description of the program.;Example;/***********************************************************************;Program Name: ProgramName.java;Programmer's Name: Student Name;Program Description: Describe here what this program will do;***********************************************************************/;How to submit your assignment;The programs MUST have the same names as the assignment title (Largest, Palindrome, Diamond).;Each Java source file (*.java) must include a corresponding class file (*.class) program as evidence of success.;In addition to the program source code files and byte code files, put all your program source code files and screen shots of your program output files into a Word document.;You must use a zipped folder to send your weekly assignment to the Dropbox. Do not send subfolders within your zipped folder. Place ALL of the.java and.class files for the week into the one zipped folder. The zip folder should be named: CIS355A_YourLastName_iLab_Week2, and this zip folder will contain all the weekly programming assignments.;iLAB STEPS;STEP 1: Largest (10 points);Back to Top;Write a Java application program called Largest.java that inputs a series of 10 single-digit numbers and determines and prints the largest of the numbers. Except main() method, no other user-defined method is required. Your program should use at least the following three variables;counter: A counter to count to 10 (that is, to keep track of how many numbers have been input and to determine when all 10 numbers have been processed);number: The current digit input to the program, and;largest: The largest number found so far.;When each number is entered, make sure it is a single digit number, that is 0 to 9.;Grading Rubric;Largest Points Description;Standard header included 1 Must contain program's name, student name, and description of the program;Program compiles 2 Program does not have any error;Program executes 2 Program runs without any error;Only single digit numbers are entered 2 Program validates number entered is a single digit number;Program displays the largest number 3 Program displays the largest number after all 10 numbers are entered;Subtotal 10;STEP 2: Palindrome (15 points);Back to Top;A palindrome is a sequence of characters that reads the same backward as forward. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554, and 11611. Write an application called Palindrome.java that asks the user to enter in a five-digit integer and determines whether it is a palindrome. If the number is not five digits long, display an error message dialog indicating the problem to the user. When the user dismisses the error dialog, allow the user to enter a new value.;Your program will have the following four methods;main() method, which controls the execution of the program;retrieveInput() method, which prompts and retrieves the input values;check() method, which determines whether it is a palindrome, and;display() method, which displays the result.;Grading Rubric;Palindrome Points Description;Standard header included 1 Must contain program?s name, student name, and description of the program;Program compiles 1 Program does not have any error;Program executes 1 Program runs without any error;Program contains main method 1 Program contains main method;Program contains retrieveInput() method 2 retrieveInput method exists, retrieves the user input, and checks if input is numeric and has five digits;Program contains check() method 2 check method exists and checks if number entered is a palindrome;Program contains display() method 2 display method exists and displays the result if palindrome or not;Value entered is numeric and has 5 digits 2 Program validates input to make sure it is numeric and has five digits;Correct output is displayed 3 Program displays the correct message for the number entered;Subtotal 15;STEP 3: Diamond (15 points);Back to Top;Write a program called Diamond.java that uses a method diamondOfAsterisks() that displays a diamond (the row number of a diamond must be odd) of asterisks whose row is specified in an integer parameter row. For example, if the user enters a 7, then the diamond will have seven rows and the method will display the pattern of asterisks. Below is an example of the diamond displayed when 7 is entered.;*;***;*****;*******;*****;***;*;Grading Rubric;Diamond Points Description;Standard header included 1 Must contain program?s name, student name, and description of the program;Program compiles 1 Program does not have any error;Program executes 1 Program runs without any error;Program contains main method 2 Program contains the main method where user is asked to enter an odd number;Program contains diamondOfAsterisks() method 3 Program contains the diamondOfAsterisks method. This method contains the code that builds and displays the diamond based on the odd number entered.;Program asks for user input 2 User must enter an odd number;Program displays correct diamond 5 The diamond must have the number of rows entered by the user;Subtotal 15
