HW 3: UCLA

Description

In this homework you are going to write 2 classes UCLAClass, UCLAStudent.

UCLAClass

It represents a class in UCLA. It has the following 3 states

class id: class id of the class, example, PIC20A
class title: title of the class, example, Introduction of Java
unit of the class. example, 4 units

The class has no public member variable. You can have other private variables.
It has the following public methods and constructors:

public UCLAClass(String classID, int units, String classTitle)
public String getClassID()
public String getClassTitle()
public int getUnits()
public void showInfo(): Print out information. The format is showed in the output of Test1.java below.

UCLAStudent

It represents a UCLA student.

student name
student ID : 9 digit student ID, you can assume that it is a long
a list of classes taken by the student, and the grades. You can assume there are no more than 100 classes taken. The grades can only be A, B, C, D and F

There is no public member variable but you can have other private variables.
The class has the following public methods and constructor

public UCLAStudent(long studentID, String name)
public long getStudentID(),public String getName()
public void add(UCLAClass aClass, char grade): add a class and the grade to the class list. The method does nothing if the number of classes taken is already 100.
double gpa() : returns the GPA of the student. The method returns 0 if there is no class taken by the student. If you don't know how to calculate GPA, ask the TA or me.
public void showStudentInfo(), public void showClasses(): print out information. The format is showed in the output of Test2.java below.

Test program

After your complete the programs, use the following 2 programs to test your programs:
Test1:

public class Test1 {
    public static void main(String[] args) {
        UCLAClass c = new UCLAClass("PIC20A", 4, "Introduction of Java");
	System.out.println(c.getClassID());
	System.out.println(c.getClassTitle());
	System.out.println(c.getUnits());
	System.out.println();
	c.showInfo();
    }
}

Output should be:

PIC20A
Introduction of Java
4

Class ID: PIC20A
Class Title: Introduction of Java
Units: 4

Test2

public class Test2 {
    public static void main(String[] args) {
        UCLAStudent charles = new UCLAStudent(502111234, "Charles Li");
	UCLAClass pic20a = new UCLAClass("PIC20A", 4, "Introduction of Java");
	UCLAClass pic10a = new UCLAClass("PIC10A", 5, "Introduction of C++");
	UCLAClass math120 = new UCLAClass("MATH120", 3, "Number Theory");
	UCLAClass math111 = new UCLAClass("MATH111", 4, "Algebra");
	charles.add(pic20a, 'A');
	charles.add(pic10a, 'B');
	charles.add(math120, 'D');
	charles.add(math111,'F');
	charles.showStudentInfo();
	System.out.println();
	charles.showClasses();
	System.out.println();
	System.out.println("GPA is " + charles.gpa());
    }
}

Output

Student ID: 502111234
Name: Charles Li

PIC20A A
PIC10A B
MATH120 D
MATH111 F

GPA is 2.125

What to submit
