How can I create a new class instance from a class within a (static) class?

Question

I\'m new to Java (have experience with C#),

this is what I want to do:

public final class MyClass
{
    public class MyRelatedClass
    {
      ...
    }         


        

Answer 1

Yes, non static nested classes have access to the outer classes instance members, and therefore must be created for an instance of the outer class. So you have two choices:

1. make the nested class static as Mervin suggests, or
2. create it using an instance of the outer class as the error message suggests.

In practice, I rarely create an instance of the inner class, except in methods of the outer class, and I rarely make such classes mutable -- but this is just me.
