An in-depth discussion of Java object Cloning (clone) and cloneable interface and serializable interfacePart IThere's nothing to say, just start Part II.Part IIWhen it comes to cloning an object, you have to say why you want to clone the object. All objects in Java are saved in the heap, and the heap is shared globally. That is, if a different method of the same Java program, as long as you can get a reference to an object, the referrer can arbitraril

After learning about the conversion between the X-Window Graphic operation interface and the Console character operation interface, you may think that each of these two operation interfaces has its own advantages, can I be greedy and have these two interfaces at the same time?

The interface of a class is the method and character set that the class allows other class objects to access. Interfaces are a promise that other interfaces will follow. The implementation of the class-to-interface is the code in the implementation class method.Java allows a class to implement multiple interfaces, and an interface is implemented by multiple class

The answer is no, in addition to the elegant app front-end display, in fact, the core is the server side. Data storage, query, message push, all in the server-side complete, silently!

Abstract class and interface are the two mechanisms in the Java language to support the definition of a class, and it is precisely because of the existence of these two mechanisms that it gives Java a powerful object-oriented capability. Abstract class and interface are very similar in terms of support for the definition of abstractions, and can even be replaced, so many developers are more likely to choose
