Java Rule Round-up Error?

[Yongtao You]

(#56) Can a method with no access modifier be overriden by a method marked protected?

Answer: Yes
Overriden methods are allowed to have LESS restriction, and since protected is less restricted than default (package), this is allowed.

--------

This is an error, right? Here is another one:

--------

(#141) an overriding method can change the access modifier from default to protected.

Answer: true

Error?

Both answers are correct. Try writing some code to see. What happens if you create a method with no modifier (default access), and try to override it with protected access? Does it work, or not?

[Georg Nieuwoudt]

This might clear up your sceptisism :
PRIVATE -> DEFAULT -> PROTECTED -> PUBLIC

a private method may be overridden by a default, protected or public method
a default method may be overridden by a protected or public method
a protected method may be overridden by a public method
and public may be overridden by a public method

reversing the process wont work other wise you will get an error msg "method cannot be more private"(something like that anyways) at compile time

[Mike Gershman]

a private method may be overridden by a default, protected or public method

How do you override a private method?

[Rajith Vidanaarachchi]

Hello,
You can give a less restricted access modifier when overriding.You can prove this by writing some code.So both are correct.
I hope you'll understand.

Ranjit, Mike is right - you cannot override a private method even thought it may appear that you are overriding it - in reality a private method is restricted to the class in which it is defined as it cannot be inherited - well now another q can you override a static method

[Steven Bell]

I just tried and you can override a static method. However the 'correct' way to call a static method would be

MyClass.staticMethod();

rather than

MyClass myClass = new SubClass();
myClass.staticMethod();

so if it is ever a problem you should probably be slapped.
