Please note: This is only a word document with the code and screenshots. Please re-code in your program.
STEP 1: Largest (10 points)
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 for the main() method, no other user-defined method is required. Your program should use at least the following three variables
1. 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);
2. number: The current digit input to the program; and
3. 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.

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
The program executes 2 Program runs without any error
Only single-digit numbers are entered 2 Program validates number entered is a single-digit number
The program displays the largest number 3 Program displays the largest number after all 10 numbers are entered

STEP 2: Palindrome (15 points)
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 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
1. main() method, which controls the execution of the program;
2. retrieve input() method, which prompts and retrieves the input values;
3. check() method, which determines whether it is a palindrome; and
4. display() method, which displays the result.

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

STEP 3: Diamond (15 points)
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.
