Illegal Thread State Exception!

[javabeginner29]

My Code is as follows:

class Example1 implements Runnable {
Thread t = new Thread(this,"Running Thread:");

public void run(){
t.start();
System.out.println("Running Thread:" + t);
}
}




class ThreadExample{

public static void main(String args[]){
Example1 X1 = new Example1();

Thread.currentThread().setName("Main Thread");


try{
System.out.println(Thread.currentThread().getName( ));
X1.run();
}
catch (IllegalThreadStateException e) {
System.out.println("Illegal Thread State Exception");
}


}
}

It is compiling fine but is giving an error while running the program...
Main Thread
Running Thread:Thread[Running Thread:,5,main]
Exception in thread "Running Thread:" java.lang.IllegalThreadStateException
at java.lang.Thread.start(Thread.java:656)
at Example1.run(ThreadExample.java:5)
at java.lang.Thread.run(Thread.java:680)

Can anyone please explain?

class Example1 implements Runnable {
Thread t = new Thread(this,"Running Thread:");

public void run(){
t.start();
System.out.println("Running Thread:" + t);
}
}




class ThreadExample{

public static void main(String args[]){
Example1 X1 = new Example1();

Thread.currentThread().setName("Main Thread");


try{
System.out.println(Thread.currentThread().getName( ));
X1.run();
}
catch (IllegalThreadStateException e) {
System.out.println("Illegal Thread State Exception");
}


}
}

Please remember to use the code tags in future :)

Read the API for Thread. You can't start() the same Thread more than once.
