Why does the following class have a syntax error?

import java.applet.*;

public class Test extends Applet implements Runnable {
public void init() throws InterruptedException {
Thread t = new Thread(this);
t.sleep(1000);
}

public synchronized void run() {
}
}

◦ You cannot put the keyword synchronized in the run() method.
◦ The sleep() method is not invoked correctly; it should be invoked as Thread.sleep(1000).
◦ The sleep() method should be put in the try-catch block. This is the only reason for the compilation failure.
◦ The init() method is defined in the Applet class, and it is overridden incorrectly because it cannot claim exceptions in the subclass.
