You seem to be asking about whether the above code is the correct way to write a method that overrides a method in its superclass.<\/p>\n

Yes it is the correct way to do it.<\/p>\n

Yes, that is a good way to “change behavior” … though you are only changing the behavior for the new class (B<\/code>)<\/p>\n

\n

What if returned objects with the ability to modify? <\/p>\n<\/blockquote>\n

Same answer.<\/p>\n

\n

As it is with returning of static and nonstatic methods? <\/p>\n<\/blockquote>\n

No. Static methods are non-polymorphic. You cannot override static methods. <\/p>\n

In your example, if bB<\/code> was static then the @Overrides<\/code> annotation would give you a compilation error. If you removed it, you would find that the call to bB()<\/code> in aA<\/code> would always call A.bB<\/code> and never B.bB<\/code>.<\/p>\n

Note that calling a static method with the syntax this.someStaticMethod(...)<\/code> is legal, but bad style. It looks like the call will be polymorphic but in fact it isn’t.<\/p>\n

\n

Whether this has any implications for concurrent programming?<\/p>\n<\/blockquote>\n

No particular implications.<\/p>\n

\n

On the other hand, if you are actually asking about methods that return other methods … your example code doesn’t do that.<\/p>\n<\/p><\/div>\n
