How to make object available for every method?

[Kacper Szmigiel]

Hello.
I have a short question. How to make object available for every method? For example i want to make object A of class ClassA and run A.make(); in one of ClassB's method. Is it available?
I greet, Kacper.

It looks like you are looking to make a public static method. This is a method that is available without instantiating object a. However, it cannot use any of the state in class A.

OK, I'vegot it. ClassB just extends ClassA and ObjectA is declarated as ClassA's variable.
Thanks.

You shouldn't be doing that just to get access to class A's members. You should only do that if a B IS-A special type of A.

and ObjectA is declarated as ClassA's variable.

So you've got this?

public class A {}

public class B extends A {
  private A a;
}

If so, that looks very wrong, though it's hard to give concrete advice on how to improve it without a more concrete picture of what you're trying to model and what you want to do with it.
