And then the front object-oriented ~ today is about the string class: In fact, the string class also contains a lot of object-oriented knowledge ~First of all, ask a question: we in the development process, if you want to use a class, it is necessary to create objects, this sentence is no problem ~ ~ in the actual development of the time is really this, only to c

Principle: Java reflection is able to get the name of a property and then invoke a method of the class by invoking it.For example, there is a property called username, this class has written a method called GetUserName, Invoke call GetUserName this method. The code is as follows Copy

Public B () {System.out.println ("Create B");} Class A extends B { static {System.out.println ("Load A");} Public A () { System.out.println ("Create A");} public class Test { public static void Main (string[] args) { A A = new A (); } The answer is Load b-->load a-->create b-->create A;The reason is a sentence: the first father, will have a son! When the program runs, load AB two classes, because
