First, Java objects are stored in the heap of memory when they are created.The initialization of a class member is performed when the object is created before the constructor initialization object is called.Package com.test.createsort;public class Createobjectsort {public static void Main (string[] args) {Test T = new Test ("Testest");System.out.println (t);}}Class test{Private String name;//class member privately, method publicPrivate String name2 =

(); Bb.test (); }}　　Look at the bold section above, name this variable is a private variable defined inside the Tagbean. This variable provides unconditional access to the SYSTEM.OUT.PRINTLN (name) in the inner class;3. Multiple inheritance can be achievedis one of the most important reasons why an internal class exists. It is because of his existence that the inheritance mechanism of Java is more perfect. We all know that

freely during the program's operation.The core part of the actual overall policy pattern is the use of abstract classes or interfaces, and the use of policy patterns can be very small and fast to modify when users need to change.There is a certain similarity between the strategy mode and the factory model. The tactical weapon is relatively simple and easy to understand, and can be switched freely at run time, while the Factory mode is primarily used to create objects.　　The strategy mode is suit
