You have just starting working at quantum company. as a new programmer, you have been asked to review and correct various pseudocode. the following pseudocode checks if an item number is valid: start declarations num sub = 0 num size = 5 num valid_item [5] = 27,53,84,89,95 string foundit = "n" input item while sub < size if item = valid_item[sub] then foundit = "y" endif sub = sub +1 endwhile if foundit = "y" then output "valid item number" else output "invalid item number" endif stop which while loop makes this more efficient?

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.
