Question

Consider that I have the two following nested classes:

public class Foo {

    public class Bar {

    }

}

And my goal is to create an instance of class Bar. I’ve tried to do it the following ways:

// Method one
Foo fooInstance = new Foo();
Foo.Bar barInstance = new fooInstance.Bar // fooInstance cannot be resolved to a type

// Method two
Foo.Bar barInstance = new Foo.Bar(); // No enclosing instance of type Foo is accessible

Any help would be highly appreciated, I’m stuck. As you might notice, I’m a Java-beginner: which doesn’t automatically make this a homework question (as a matter of fact – it isn’t).

How can one create an instance of the Bar class? Preferably with the same Foo instance.

Answer 1

Close. Instead write:

Foo.Bar barInstance = fooInstance.new Bar();
