Overridden method

[Harikrishna Gorrepati]

Hi, Why Line6 is not valid override as per whizlabs mock exam

class OtherTest {
    private int amethod(float i) {return 0;}
}

public class Test extends OtherTest{
    private int amethod(float i) {return 0;}
}    

[Stephan van Hulst]

Because amethod in OtherTest is private.

Thanks Stephan. This is from Whizlabs. Drag and Drop one of the following to Line # 8 and 10 so that given program compile and run
I. private int amethod(float i) {return 0;}
II. void amethod(int i) throws RuntimeException

class OtherTest {
    void amethod(int i){}
    
}

class MyTest extends OtherTest{
    
} 

I was thinking that answer would be

class OtherTest {
    void amethod(int i){}
    private int amethod(float i) {return 0;}
}

class MyTest extends OtherTest{
    private int amethod(float i) {return 0;}
}    

But, the answer is..Why ?

class OtherTest {
    void amethod(int i){}
    private int amethod(float i) {return 0;}
}

class MyTest extends OtherTest{
    void amethod(int i) throws RuntimeException {}
}

When we write method in the super class as private
and override using another method in subclass
it is not considered overriding at all as the private method is not accessible to the subclass
and
throwing RuntimeException by overriding method is allowed even if the superclass method does not throw exception

for this you have to check out rules for overriding neatly

happy preparation

Hi Prasad, Question doesn't refer anything about overriding..All it says is "compile & run"

I know friend
but read the rules for overriding and you will come to know what the problem is
happy preparation

I have gone through all rules. Anyways, overriding rule doesn't apply here in this code. Let me put it this way. Even if I use either 2nd or 3rd code snippet, It compiles & runs fine. Please advice.

this time you are right harikrishna...

If I may, I have seen lots of really poor examples of code from WhizLabs. I don't know if they come highly recommended, but from all their code I've seen posted on this site, I would never even consider using them.

Agree. In my opinion best would be the K&B Guide (CD)+ExamLab. On exam- there are tricky questions but few are at times easier.

Harikrishna Gorrepati, your answer also correct as like one they provided. But, they may want not to use the same code snaps for the two blanks.

Mu personal experience, don't use Whizlabs, I used it for my SCWCD preparation, but, not worth and making us confusing. There are many other useful mocks, like ExamLab. Use then as a study guide. This is my personal experience!
