Term 2: Lesson 5 - Coding Activity

For this exercise, you will create a Student class to hold student data. In previous exercises, we had a requirement that you name your class Main. In this exercise, you must name your class Student.

Your Student class should include the following information: first name, last name, grade level, GPA, and a student id. Grade level is an integer value ranging from 0 to 12, with 0 representing kindergarten. GPA is a decimal value ranging from 0 to 4.5. Student id is an integer value. The first student id is 1, the second student id is 2, the next is 3, and so on. When a new Student is created, your code should automatically initialize student id to the next integer value. For example, if the last created Student's student id is 17, the next student id generated should be 18.

Your student class should include the following methods:

• Student() - Constructs a new student with first name and last name set to "None", grade level set to 0 and GPA set to 0.0. The student id should automatically be set to the next integer.
• Student(String firstName, String lastName, int gradeLevel, double gpa) - Constructs a new student with variables initialized to the values specified. The grade level should only be allowed to range between 0 and 12 inclusive, 0 represents kindergarten. Otherwise, set the grade level to 0. The GPA should only be allowed to range from 0.0 to 4.5, inclusive. Otherwise, set the GPA to 0.0. The student id should automatically be set to the next integer.
• String toString() - Returns the student information as a String in the following format (notice line breaks after the first name and GPA):

  Dovi, Mrs GPA: 4.0 Grade Level: 7 id # 4

To test your code prior to submission, download the runner class student_runner_Student.java (Links to an external site.) to the same folder that holds your Student.java implementation. Run student_runner_Student.main class and verify that the output matches the sample run below. Please feel free to change the runner to test different values to make sure your program fits the requirements. We will use a similar runner class to grade the program.

Sample Run

None, None GPA: 0.0 Grade Level: 0 id # 1 None, None GPA: 0.0 Grade Level: 0 id # 2 None, None GPA: 0.0 Grade Level: 0 id # 3 Dovi, Mrs. GPA: 3.4 Grade Level: 7 id # 4
