Java Internal classes

Inner classes in Java have member inner classes, static inner classes, local inner classes, and anonymous inner classes.

 Public classOuterclass {Private inti = 1; Private Static intj = 2; //member Inner class    classInnerClass1 { Public voidprint () {System.out.println ("InnerClass1 Print:" +i); }    }        //static inner class    Static classInnerClass2 { Public voidprint () {System.out.println ("InnerClass2 Print:" +j); }    }         Public Static voidMain (string[] args) {Outerclass.innerclass1 inner1=NewOuterclass ().NewInnerClass1 ();        Inner1.print (); Outerclass.innerclass2 Inner2=NewOuterclass.innerclass2 ();        Inner2.print (); //local inner class        classINNERCLASS3 { Public voidprint () {System.out.println ("INNERCLASS3 Print:" +j); }} INNERCLASS3 Inner3=NewINNERCLASS3 ();        Inner3.print (); //Anonymous Inner class        NewThread (NewRunnable () {@Override Public voidrun () {System.out.println ("INNERCLASS4 Print:" +j);    }}).
