Two methods for realizing a thread
Shan brother http://blog.9cbs.net
Java completes multithreading through the Java.lang.Thread class. Through the same example, we look at the two creation methods of threads, and how to operate
One is a subclass of Thread, and the method of overloading the Thread class Run Extend java.lang.thread and Override the Run Method.
Public class mythread extends thread {public void run () {// Because the default Run () method does nothing, you must create Thread subclasses and overload Run () to complete useful work. For (int count = 1, row = 1; ROW <20; Row , Count ) {for (int i = 0; i There are two methods, A, B. Public static void main (String [] args) {mythread mt = new mythread (); // a mt.start (); // a thread mythread = new thread ()); // b mythread.start ( ); // b for (int i = 0; i <500; i ) {system.out.println (i);}} Another way is to declare a class that implements the Runnable interface. Then implement method Run. Implement java.lang.Runnable and import the run method. // public class mythread extends thread {public class mythread implements runnable {public void run () {for (int count = 1, row = 1; row <20; row , count ) {for (int i = 0; i There is only one method B at runtime. Public static void main (String [] args) {// mythread mt = new mythread (); // mt.start (); thread mythread = new thread (); mythread.start (); for (int); I = 0; i <500; i ) {system.out.println (i);}}
