Is the following a mis-type.
- Create a Student class as following:
- The Student class has StudentRecord class as an instance variable.
Name it as studentRecord.
- You can use the StudentRecord class from the
MyStudentRecordExampleProject above or you can create a new
one - the only
requirement is that it has to have at least one instance
variable of its
own.
- The Student class has studentId instance variable whose type is
Integer type.
- Move the studentCount static variable from the StudentRecord class
to Student class.
- Rewrite main.java as following
- Create 3 instances of Student class and initialize them accordingly
- use whatever initialization values that are appropriate.
- Display the information of each student including the student id,
name.
- Display the studentCount.
If not why would we introduce another class into this project.
If so I'm a bit confused?
Below is a copy with the instructions given. And I would like a some help on
how to handle the student count.

public class Student {
// instance variable of Student ID
String studentID;
// Declare static variables.
//studentCount static variable moved from StudentRecord class Now if we
move this variable shouldn't the methods as well. Unless we set the main
method here.
static int studentCount = 0;
// Instance Variable of StudentRecord
StudentRecord studentRecord = new StudentRecord();
public Student()
{
}
public Student(String sID, String name , double sGrade )
{
//
studentID = sID;
//increase student count Error cannot access static methods for
non-static context(method)
studentRecord.increaseStudentCount();
studentCount = studentRecord.getStudentCount();
//set name
studentRecord.setName(name);
//set English Grade
studentRecord.setEnglishGrade(sGrade);
}
}
