Question

Is it possible to get an object that invoked static method in this method?

I have this code:

class A{
    static void foo(){
    }
}
A a = new A();
a.foo();

Can I get instance a in method foo() ?

Answer 1

Firstly, your code isn’t good as a programmer.

It is because static methods are class-level methods and should be called without any instance of class.

Recommended approach :

class A{
    static void foo(){
    }
}
A.foo();

Can I get instance a in method foo() ?

Nope, you can’t. Because foo() is declared as static. So you can’t use this inside that method, since this contains a reference to the object that invoked the method.
