not depend on it. As a simple example: if you create a daemon thread in the main thread, when the main method finishes running, the daemon thread will die as well. The user thread does not, and the user thread runs until it finishes running. In the JVM, a garbage collector thread is the daemon thread.The thread class has a more commonly used static method, CurrentThread (), to get the current thread.The most of the methods in the thread class have been mentioned above, so how does a method call

First, the object-oriented five basic features:1. All things are objects. treats an object as a peculiar variable, he can store the data, and can require it to perform operations on itself.2. A program is a collection of objects that they tell each other to do by sending a message.3. Each object has its own storage that is composed of other objects. in other words, you can create a new type of object by creating a package that contains an existing object.4. No object has its type. The most impor

example: The purpose is to put the elephant into the refrigerator, objects have, elephants and refrigerators, elephants to put in the refrigerator, need to put the refrigerator before the notice, open the door, the elephant in, notify the refrigerator, close the door.Three: Each object has its own storage that is composed of other objects. This is not discussed first.Four: Each object has its type. An object is an instance of a class, such as: An elephant is a class, but not a specific thing, t

improve the user experience of graphical software and prevent the "freezing" phenomenon from arising.Risk of threading:The first risk is that the execution sequence cannot be determined under multithreading, and there is an unexpected situation. Using the Java synchronization mechanism can improve the problem.The second risk is the case where a deadlock, such as a program, cannot continue.The third risk is that in multi-threading, thread scheduling a
Prime A Prime is an integer greater than one whose only positive divisors is one and itself.The prime factor decomposition of an integer is a collection of the product equal to this prime number.Example: 3757208 = 2*2*2*7*13*13*397 Public classfactors{ Public Static voidMain (string[] args) {//Print The prime factors of N. LongN = Long.parselong (args[0]); Longn =N; for(Longi = 2; I ) { //Cast out and print I factors while(n% i = = 0) {n/=i; System.out.print (i+ " ");
Public classbinary{ Public Static voidMain (string[] args) {//Print binary representation of N. intN = Integer.parseint (args[0]); intv = 1; while(v ) v=v; //Now V is the largest power of 2 intn = n;//Current Excess while(V > 0) { //Cast out the power of 2 in decreasing order. if(N ); } Else{System.out.print (1); n-=v;} V= V/2; } System.out.println (); }}Prints a binary representation of a 10-decimal number.

Swing was a GUI framework developed by Sun, and at the outset sun was developing the AWT framework. However, the AWT framework has LCD problems. As a result, Sun continued to develop swing on the basis of AWT. Swing is a class that inherits the AWT common components: Text text component Menus menu component Widgets Widget component Top-level-windows Top-level window Management sub-windows child windowOne of the Java GUI

Although it's a good piece of information to improve your technology, it may be annoying if you've had a long socket development experience on your PC or other platform, but if you don't really understand the socket and just want to know what the socket is and How to apply the socket to your Java code ", this tutorial is a good start."
