Threads
Hi,
I want to understand Threads in Java programming. I have 3 classes:
public class MainClass extends Thread {
public MainClass(){
}
public static void main(String[] args) {
Thread1 thread1 = new Thread1();
Thread2 thread2 = new Thread2();
MainClass m = new MainClass();
m.start();
thread1.start();
System.out.println("thread1 start");
thread1.run();
System.out.println("thread1 run");
thread2.start();
System.out.println("thread2 start");
thread2.run();
System.out.println("thread2 run");
}
public void run(){
System.out.println("main thread");
}
}
class Thread1 extends Thread {
private Thread2 thread2;
public Thread1(){
thread2 = new Thread2();
}
public void run(){
thread2.start();
System.out.println("thread1 is current");
}
}
class Thread2 extends Thread {
public void run(){
System.out.println("thread2 is current");
}
}
Can someone tell me wat is wrong with this code?What is the different beetween run() and start()?
