Write a program that calculates the sum of the squares of the integers from 1 to MySquare, where MySquare is input by the user. Validates user input by checking to make sure that the input is a positive integer. Declare and uses valid variables with the appropriate data types. Student evaluates the input, processes the data and determines the appropriate solution.
i. Create formulas that can produce correct result.
ii. Incorporate user-friendly displays.
iii. Show mastery of algorithm design.
iv. Incorporate logical conditions that covers all boundaries specified by the problem.
v. Use defensive programming techniques.

8. create an abstract student class for parker university. the class contains fields for student id number, last name, and annual tuition. include a constructor that requires parameters for the id number and name. include get and set methods for each field; the settuition() method is abstract. create three student subclasses named undergraduatestudent, graduatestudent, and studentatlarge, each with a unique settuition() method. tuition for an undergraduatestudent is $4,000 per semester, tuition for a graduatestudent is $6,000 per semester, and tuition for a studentatlarge is $2,000 per semester. write an application that creates an array of at least six objects to demonstrate how the methods work for objects for each student type. save the files as student.java, undergraduatestudent.java, graduatestudent.java, studentatlarge.java, and studentdemo.java.
