How to restart thread in java? [duplicate]

Answer 1

If a thread is dying due to an uncaught exception, the answer is simple: catch the exception at an appropriate place so that you can keep going. Either catch the exception within your searchfile method, or make the run method call searchfile in a loop.

Answer 2

I'm not entirely sure if this will work, yet here's a try.

public void run() {
    try {
        searchFile();
    } catch(Exeption e) {
        e.printStackTrace();
        if(!Thread.currentThread().isAlive())
            Thread.currentThread().start();
    }
}
