How can i create a instance of the following Class and access its methods. Example:
public class A { public static class B { public static class C { public static class D { public static class E { public void methodA() {} public void methodB(){} } } } } } You can use :
A.B.C.D.E e = new A.B.C.D.E();//create an instance of class E e.methodA();//call methodA e.methodB();//call methodB Or like @Andreas mention in comment you can use import A.B.C.D.E;, so if your class is in another packager then you can call your class using name_of_package.A.B.C.D.E like this:
import com.test.A.B.C.D.E; // ^^^^^^^^------------------------name of package public class Test { public static void main(String[] args) { E e = new E(); e.methodA(); e.methodB(); } } 
import A.B.C.D.E; E e = new E();. And you need to qualify first E too, without the import. --- And for completeness, you might mention how it works if A is in a package.
Arrsyss? If that was supposed to be example for package, then it should be lowercase, and a better example might be org.example.
A.B.C.D.E e = new A.B.C.D.E();not sure what "How" means.static, they are generally called static nested classes. They are definitely not inner classes. JLS §8.1.3. Inner Classes and Enclosing Instances: An inner class is a nested class that is not explicitly or implicitly declaredstatic.
