If I wanted to increment a number

Question

I want to increment a student number in a constructor. What is the best way? I have to call this from a display method. Here is what I have so far:
    int     stuNo;
    private static  int     studentNumber  = 100;
    public Student()
        getStudentNumber();
     *  Sets the studentNumber attribute of the Student object
    public void setStudentNumber()
        stuNo = studentNumber + 1;
     *  Gets the studentNumber attribute of the Student object
     *@return    The studentNumber value
    public int getStudentNumber()
        return stuNo;
    }With this code I keep getting the same number(100) for my display. Any help is looked upon in great admiration.

Answer 1

public class Student
int stuNo; // this should probably be a final field
private static int studentNumber = 100;
public Student()
stuNo = studentNumber++; // increments static field
// studentNumber
* Sets the studentNumber attribute of the Student
* object
public void setStudentNumber(int stuNo)
// You probably do not want a modifier on an
// autoincremented field, since it is like an
// primary key???
this.stuNo = stuNo;
* Gets the studentNumber attribute of the Student object
*@return The studentNumber value
public int getStudentNumber()
return stuNo;
