Method Local Inner Class

public class Test {
    public static void main(String[] args) {

    }
}

class Outer {
    void aMethod() {
        class MethodLocalInner {
            void bMethod() {
                System.out.println("Inside method-local bMethod");
            }
        }
    }
}

Can someone tell me how to print the message from bMethod?

You need to call new Outer().aMethod() inside your main method. You also need to add a reference to MethodLocalInner().bMethod() inside your aMethod(), like this:

public class Test {
    public static void main(String[] args) {
        new Outer().aMethod();
    }
}


void aMethod() {
    class MethodLocalInner {
        void bMethod() {
            System.out.println("Inside method-local bMethod");
        }
    }
    new MethodLocalInner().bMethod();
}

You can only instantiate MethodLocalInner within aMethod. So do 

void aMethod() {

    class MethodLocalInner {

            void bMethod() {

                    System.out.println("Inside method-local bMethod");
            }
    }

    MethodLocalInner foo = new MethodLocalInner(); // Default Constructor
    foo.bMethod();

}

Why don't you just create an instance of MethodLocalInner, in aMethod, and call bMethod on the new instance?

Within the method aMethod after the declaration of the class MethodLocalInner you could for instance do the following call:

new MethodLocalInner().bMethod();
