Hello,

Given:

//Insert code here

public abstract void draw();
}


//Insert code here
public void draw(){ System.out.println("in draw..."); }
}
Which of the following lines of code can be used to complete the above code?

--I thought if an class contained abstract methods it was automatically represented as an abstract class so that in the case of the first option:

class Shape {

and

class Circle extends Shape {

--class Shape would become an abstract method. Thanks

I am not sure what you mean by, "class Shape would become an abstract method.". A class cannot become a method.

If a class has an abstract method, it must be declared as abstract.

Sorry you're right. Wouldn't class Shape become an abstract class?

Yes, but you still have to put abstract keyword in the class declaration to make it compile.

General Question: How indicative of the real test is/was this last day test? Thanks

[admin]

Quite indicative.

Had this been an option would it be correct:

Code: Select all

public abstract class Shape {  
and  
public class Circle  extends Shape {

and also this one:

Code: Select all

abstract class Shape {  
and  
class Circle  extends Shape {

1. Yes.
2. Yes.
