overiding in java

Hi.

There is no way to do this in general (it can be achieved to some extent for local classes, but I don't think that's what you're after).

However, are you sure you need to do this? It implies the caller is taking on responsibilities that it shouldn't have. Sounds like a flawed design somewhere...

One way to achieve something like what you're after is not to override at all (which means you lose the polymorphic effect). Rather than doing:

abstract class A {

public void doStuff() {

...

}

...

}

class B extends A {

public void doStuff() {

...

super.doStuff();

...

}

...

}

do:

abstract class A {

public void doStuff() {

...

}

...

}

class B extends A {

public void doMoreStuff() {

...

doStuff();

...

}

...

}

Rather than overriding, this leaves A.doStuff() available for clients to call as well as providing another method in B (doMoreStuff()) that has the same effect as the original overriding method.
