The IOC (inverse of control) can be translated as "controlling reversal," but most people are accustomed to calling it "dependency injection". In spring, the IOC can configure the implementation class, parameter information, and so on in its corresponding configuration file, so that if you need to change the implementation class or parameter information, you only need to modify the configuration file, which

Java Dynamic Planning: coin failover implementation code; java failover
The basic idea of dynamic planning is to break down the problem to be solved into several subproblems, first solve the subproblems, and save the solutions to these subproblems, if you need to solve these subproblems in the future, you can directly retrieve these computed solutions without rep
The functionality and code design of the application takes into account the need to run in different regions, and its code simplifies the production of different local versions. The process of developing such a program is called internationalization. Today, we begin to learn about the internationalization of code implementations in Java.Java internationalization is mainly done by the following 3 classes

This defines two inner classes, each inheriting the Father Father class, the mother class mother class, and all can be very natural to get the behavior of their parent cla

implement multi-threading, in fact, after contact we will find that this is completely two different implementations of multi-threading, one is multiple threads to complete their own tasks , one is that multiple threads work together to complete a task .In fact, in the implementation of a task with multiple threads to do can also be used to inherit the thread class to achieve is just more trouble, generally we use the
Java applet ball Big Battle (based on Java thread implementation)
first, the basic functions of the game:
1, their own small ball can be moved with the mouse to change the coordinates;
2, the enemy ball constantly moving in the interface
3. When the enemy ball is detected colliding with each other, the ball will bounce off
4, when our small ball collision with t
There are two ways to implement multithreading in Java, one is to inherit the thread class and the other is to implement the Runnable interface.
For both implementations, each has its advantages and disadvantages. Next, compare and summarize. Both of these methods can be implemented in multithreading. here are two ways to implement
how the thread class is inherited:

public class Mythread extends Thread {
private String name;
