No, Once you have started a
thread, it can not be started again. If you try to start thread again , it will throw IllegalThreadStateException
Lets understand with the help of example:

package org.arpit.java2blog;
class FirstThread extends Thread {
public void run() {
System.out.println("Thread is running");
}
}
public class StartThreadAgainMain {
public static void main(String[] args) {
FirstThread ft = new FirstThread();
ft.start();
ft.start();
}
}

When you run above program , you will get below output:
|
|
Thread is runningException in thread "main"
java.lang.IllegalThreadStateException
at java.lang.Thread.start(Thread.java:705)
at org.arpit.java2blog.StartThreadAgainMain.main(StartThreadAgainMain.java:16)
As you can see when we started thread twice, it threw IllegalThreadStateException.

If you try to start thread again , it will throw IllegalThreadStateException
