advantage is based on the mechanism of shared objects, to achieve a high degree of information sharing, that is, eliminates duplication of class information creation and recycling by saving and holding the state of an object . Once an object is created, it can be held and used by people. Dynamic loading theoretically can replace this object directly, and then update all references to the original object in the Java stack, but it is still not feasible, because it violates the design principle of

the class is loaded, used to initialize the class, and is called only once, and the new object is no longer called.Instantiating an initialization block is different, it is executed once every time the object of the class is instantiated, and it executes before the constructor call.In addition, we have learned the concept of an inner class, which is a redefinition of the class within the class. There are four types of Java internal classes: Static inner class, member inner class, local inner cl

able to understand the JSONP of the client implementation of the principle of it? The rest is how to encapsulate the code to make it easier to interact with the user interface for multiple and repeated calls.What the? You're using jquery, and you want to know how jquery implements JSONP calls? Well, then I'll give you a good one. jquery uses the JSONP code (we still use the example of the flight information query above, assuming the return JSONP result is the same):OK, the server is very smart,

– because of potions. And you had the town Portal, which could instantly get to any problem. Those were incredibly powerful mechanics to escape danger and were not class-specific. So every kind of class really had no need for anything like an escape skill or reactionary ability. They simply needed to attack, and if they ever got on over their heads, they simply ran away or drank potions. And it ' s the same response across the board. So one of the things we focused on was that response--1) Sett
