Class declarations and object modeling: Correct Solution

Translate the specification below into an idiomatic Java class definition.

(In this context, "idiomatic" means following the common style and conventions of the language.)

1. One kind of thing that exists in our model is a Cirkcing.

2. Each Cirkcing has its own velir, which is an int. The value of velir starts out as 18. Anyone can ask a Cirkcing for the value of its velir. Anyone can set velir to a new value.

Solution

public class Cirkcing {
    private final int velir;

    public Cirkcing() {
    }

    public int getVelir() {
        return velir;
    }
}

Things to check in your solution:

• Is every public and private modifier correct?
• Are the correct items static?
• Are the correct items final?
• Are all the variable types and method return types correct?
• Are the class members in the correct order? It should be: (1) static variables, (2) instance variables, (3) constructors, (4) methods.
• Do members have the correct capitalization?

Acceptable variations in the solution:

• It is OK if you initialized non-static variables in the constructor instead of in the declaration. (Ask your instructor if you aren’t clear what this means.) Note that static variables must be initialized in the declaration.
• It is OK if you used a slightly different but equivalent form of an expression, such as += 1 instead of ++.
