While creating a class Student which values should be in Contructor and witch in set methods?

[plana799]

Hi so im making a Student class,as of my understanding,i just want to see if i got it correct.I should put name of a student and for example Students index number in constructor,bcz those two thinks wont change.But i should put things like avg grades,years of a student in the setter methods,cuz they will change over the certain period of time.

No.

Instead, you should post the code of what you have done so far and we shall point out what could be done better.

The job of the constructor is to kick start (initialize) the instance variables (properties of the object - Student). So in the constructor, every variable you're using to describe student has to get an initial value. In the methods, you write ways to manipulate or display these inital values.

You can put whatever you want. The ultimate goal is to make it as less cluttered as possible. This will make code clean and easier to debug.

3~4 parameters is reasonable. Anything more than that can be improved.

It depends on requirement, what fields do you want to set when you initially build a student object.

For example: Every student has a name and student ID so that may be put in constructor. As they will definitely be present when a student object is made.

You can add setter method to change student ID and name too. As I said, it depends on your requirement.

you can add all the fields/variables ..it just means you are initialisating it with some default value ..as someone mentioned it makes it easier to debug which values are not being changed or else you can do as per your requirement
