So please correct it!!! Remember: 'default' access modifier is package-private which means every class (whether extending it or not) within same package can access it. –

Jul 23, 2015 · Before Java 8, if a new method was added to an interface, then all the implementation classes of that interface were bound to override that new method, even if they did not use the new functionality. With Java 8, we can add the default implementation for the new method by using the default keyword before the method implementation.

Apr 20, 2017 · You have two choices for setting the default value of an instance variable (sometimes called an "instance field"): Using an initializer on the declaration. Using an assignment in a constructor. Say I have a class Example and an instance variable answer whose default should be 42. I can either:

Sep 9, 2012 · A nested class, that is, a class inside of another class, can be made public, package-private, protected, or private, just like any other class member. The default (i.e., the one with no modifier) is package-private, visible only to classes in the same package. EDIT: Forgot the C++ answer, so see (and upvote) @zeller's answer.

Not to be confused with the new Java 8 feature (Default Methods) that allows an interface to provide an implementation when its labeled with the default keyword.

Jul 8, 2021 · In the absence of any other explicit superclass, every class is implicitly a subclass of the Object class. Points to understand first: There is a class Object in java which is already available with the JRE libraries. When you define a class without an extends keyword, your class will by default extend the Object class in Java.

Mar 2, 2016 · create a public class in the same package with your default class then use Proxy pattern or Delegate pattern to access the default class. Eclipse supports auto generate delegate pattern. From other packages, you can access the default class via the public class –

Aug 17, 2013 · Java 8 introduces “Default Method” or (Defender methods) new feature, which allows developer to add new methods to the interfaces without breaking the existing implementation of these interface.
