Is not an enclosing class Java

Question

Shape is not an enclosing class

when I try t

Answer 1

Sometimes, we need to create a new instance of an inner class that can't be static because it depends on some global variables of the parent class. In that situation, if you try to create the instance of an inner class that is not static, a not an enclosing class error is thrown.

Taking the example of the question, what if ZShape can't be static because it need global variable of Shape class?

How can you create new instance of ZShape? This is how:

Add a getter in the parent class:

public ZShape getNewZShape() {
    return new ZShape();
}

Access it like this:

Shape ss = new Shape();
ZShape s = ss.getNewZShape();
