Review Assignment

Step One: Make the Student class

A student has:

• a firstName (String)
• a lastName (String)
• an array of grades (int[])

Write the following methods:

• getter methods for all instance variables
• a method getAverage() that returns a floating point average of the values in grades.
• a toString() method that displays first, last, the student's grade average, then each grade. The format should look something like this:

Jackson, Joe Average: 95.0 Grades: 90 95 100

Step Two: Test the Student class

Instaniate one or more Student objects in Main. Check to see if your methods work.

Step Three: Make the Teacher class

A teacher has:

• a firstName (String)
• a lastName (String)
• a salary (double)

Write the following methods:

• getter methods for all instance variables

• a method getWeeklySalary that returns the amount that this teacher should be paid each week (52 week year).

• a toString() method that prints a teacher's information in a similar format to this:

  McTeach, Teachy Salary: $100,000.00*

(note to get the currency formatting you can declare a NumberFormat object in Techer as follows)

private final static NumberFormat FORMATTER = NumberFormat.getCurrencyInstance();

Then call on the format() method of FORMATTER, which accepts a double and returns a (formatted) String.

Step Four: Test the Teacher class

Instantiate one or more Teacher objects in Main. Make sure all of the methods in teacher work correctly.

Step Five: Redesign your classes using inheritance

You likely have noticed that there are some common features between theStudent and Teacher classes.

Design a class Person that incorporates all of the common attributes. Refactor the child classes accordingly.

Thought question: Should the Person class be abstract? Why or why not?

Step Six: Check your work

Confirm that both Student and Teacher objects still work as expected

Step Seven: Create an ArrayList of type Student called allStudents.

Make allStudents static, and declare it outside of any method. This will allow you to reference it any any of the methods that you write.

In main(), populate allStudents with a minimum of 4 student objects.

Step Eight: Create the following menu inside of Main:

1. show all students
2. find student by name
3. generate honor roll

Before you write the code that makes each menu option work, make the menu itself work:

• The menu must only accept the #s 1 through 3 (inclusive).
• Any other value results in an error message
• An invalid selection results in the user getting the menu prompt again, with another chance to enter a proper value.

Step Nine. Write the method showAllStudents()

The method is called if the user selects option 1. It should iterate through allStudents and display each using a call to toString()

Step Ten: Write the method findStudentByName()

This method is called if the user selects option 2. It accepts a String, then return the first student whose name contains that String. If the search term is not found, the method returns null.

Step Eleven: Write the method generateHonorRoll()

This method is called if the user selects option 3. This method iterates through allStudents and returns a List of all Students whose average is above an 85.
