Assignment Overview
This programming exercise introduces generics and interfaces. The students must create methods that accept generic parameters and perform operation on them.
Deliverables
A listing of the fully commented, working source code of the Java program
Test data for the code
A screen shot of the application in execution

Step 1 Create a new project.
Name it \"Assignment_2_1\".

Step 2 Build a solution.
Write the Java source code necessary to build a solution for the problem below:You have just taken a new \"Teach for America\" job in a very rural, impoverished neighborhood. The school system does not provide you with any tools. You decide to write a new gradebook program. You need your new gradebook to allow you to sort the students by NAME or by highest grade on a test so that you can fill out all of the many district reports on your students\' progress. Remembering that sometimes Java lets you write one method and use it many times, you decide to write a generic method that will return the maximum and minimum element in a two-dimensional array (your gradebook, NAME, SCORE). Test the program using an array of random integers and again using an array of random names.
In order to do the comparison of names you need to understand the Java Character encoding scheme (Links to an external site.).
You should check this site to understand which character is bigger (\"A\" or \"Z\") and then work from there.
Print the array sorted by SCORE, then use it again and print the array sorted by NAME.
MUST USE GENERICS OR I WILL NOT RATE

Step 3 Compile and execute your code.
Be sure to test the solution using a set of input data that demonstrates your solution is correct. Take a screen shot of your NetBeans® IDE showing the output from your Java program.
