public class MyOuter { public static class MyInner { public static void foo() { } } } which statement, if placed in a class other than MyOuter or MyInner, instantiates an instance of the nested class?

public class MyOuter
{
public static class MyInner
{
public static void foo() { }
}
}

which statement, if placed in a class other than MyOuter or MyInner, instantiates an instance of the nested class?

[A].	MyOuter.MyInner m = new MyOuter.MyInner();
[B].	MyOuter.MyInner mi = new MyInner();
[C].	MyOuter m = new MyOuter(); MyOuter.MyInner mi = m.new MyOuter.MyInner();
[D].	MyInner mi = new MyOuter.MyInner();

Answer: Option A

Explanation:

MyInner is a static nested class, so it must be instantiated using the fully-scoped name of MyOuter.MyInner.

Option B is incorrect because it doesn't use the enclosing name in the new.

Option C is incorrect because it uses incorrect syntax. When you instantiate a nested class by invoking new on an instance of the enclosing class, you do not use the enclosing name. The difference between Option A and C is that Option C is calling new on an instance of the enclosing class rather than just new by itself.

Option D is incorrect because it doesn't use the enclosing class name in the variable declaration.

public class MyOuter { public static class MyInner { public static void foo() { } } } which statement, if placed in a class other than MyOuter or MyInner, instantiates an instance of the nested class?
