java支持多线程吗_java中支持多个线程同时运作！
public static void main(String[] args){ Runnable status_runnable=GenerateStatus();
Runnable session_runnable=MyThread(session);
Thread statusThread=Thread(status_runnable);//线程中放了任务
Thread session_thread=Thread(session_runnable);
statusThread.start();
session_thread.start();
}
两个类的实现如下，第一个是GenerateStatusimport java.util.Random;
public class GenerateStatus implements Runnable{
private String temperature;
private String free_Space;
public GenerateStatus(){
/*构造方法*/
}
/*线程中运行的程序*/
public void run() {//这里因为实现接口这个必须实现
Random random=new Random();
while(true)
{
temperature =((Integer)(random.nextInt(70)+20)).toString();
free_Space=((Integer)(random.nextInt(100)+1)).toString()+"G";
StatusMap.put("temperature",temperature);
StatusMap.put("free_Space",free_Space);
System.out.println("test");
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
第二个类MyThread
javax.websocket.Session;
java.io.IOException;
MyThread Runnable {
String ;
String ;
Session ;
MyThread(Session session) IOException {
.=session;
}
run() {
(){
{
Thread.();
} (InterruptedException e) {
e.printStackTrace();
}
System..println();
=StatusMap.();
=StatusMap.();
{
.getBasicRemote().sendText();
.getBasicRemote().sendText();
} (IOException e) {
e.printStackTrace();
}
}
}
}
PS:若只需一个线程，就可以直接建立个线程使其继承Thread,在主函数中直接调用。Thread statusThread=new MyThread(session);
statusThread.start();//这样就可以了。但是不能多个线程同时运行！
public static void main(String[] args){ Runnable status_runnable=GenerateStatus(); Runnable session_runnable=MyThread(session); Thread statusThread=Thread(status_runnable);//线程中放了任务 Thread session_thread=Thread(session_runnable); statusThread.start(); session_thread.start(); } 两个类的实现如下，第一个是GenerateStatusimport java.util.Random; public class GenerateStatus implements Runnable{ private String temperature; private String free_Space; public GenerateStatus(){ /*构造方法*/ } /*线程中运行的程序*/ public void run() {//这里因为实现接口这个必须实现 Random random=new Random(); while(true) { temperature =((Integer)(random.nextInt(70)+20)).toString(); free_Space=((Integer)(random.nextInt(100)+1)).toString()+"G"; StatusMap.put("temperature",temperature); StatusMap.put("free_Space",free_Space); System.out.println("test"); try { Thread.sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } } } } 第二个类MyThread javax.websocket.Session; java.io.IOException; MyThread Runnable { String ; String ; Session ; MyThread(Session session) IOException { .=session; } run() { (){ { Thread.(); } (InterruptedException e) { e.printStackTrace(); } System..println(); =StatusMap.(); =StatusMap.(); { .getBasicRemote().sendText(); .getBasicRemote().sendText(); } (IOException e) { e.printStackTrace(); } } } } PS:若只需一个线程，就可以直接建立个线程使其继承Thread,在主函数中直接调用。Thread statusThread=new MyThread(session); statusThread.start();//这样就可以了。但是不能多个线程同时运行！
