Java Experiment 7-multithreaded programming

1 Creating Threads with Thread and Runnable

"Experimental Purpose"

(1) Understanding the implementation of the Runnable interface method to achieve multithreading.

(2) Mastering the setting of thread priority.

(3) Deepen the understanding of thread state transitions.

"Experimental Requirements"

Requirement one: Using multi-threading to realize rotating planets

Request two: Write a threadSyncdemo, design a method for itPublic class GetNumber ()from1Start counting to -stop. Where two synchronous threads are designedAthreadand theBthread, all withGetNumber ()Scramble for this -number. Note ThreadAthreadand theBthreadsynchronization control, which guarantees counting to -is stopped.

Requires two codes

Class Syncdemo implements Runnable {static int num = 1;public synchronized Boolean getnumber () throws Exception {THREAD.SL EEP, if (num <=) {System.out.println (Thread.CurrentThread (). GetName () + "" +num++); return true;} return false;} public void Run () {try {while (GetNumber ())} catch (Exception e) {//TODO auto-generated catch Blocke.printstacktrace ();} }}public class Fd {/** * @param args */public static void main (string[] args) {//TODO auto-generated method Stubsyncdemo Demo = new Syncdemo (); Thread athread = new Thread (demo, "A"); Thread bthread = new Thread (demo, "B"); Athread.start (); Bthread.start ();}}
