Question

How to call methodTwo(); from methodOne(); ?

class Name {
    void methodOne() {
        class InnerClass {
           void methodTwo() {
           }
         }
     }
 }

Thank You!

You need to create an instance of the InnerClass, in the same way as any other instance method needs an instance on which to call it:

class Name {
   void methodOne() {
     class InnerClass {
       void methodTwo() {
       }
     }

     InnerClass x = new InnerClass();
     x.methodTwo();
   }
}

It’s worth being careful before doing this – I don’t think I’ve ever seen a named class declared within a method in the production code I’ve been associated with. Normally I’d either use an anonymous inner class for something really short, or a private static named class for anything longer, to avoid making the method too long.
