Write a program that will surely go into deadlock [closed]

Answer 1

Here is a Java example by following Eric Lippert's one:

public class Lock implements Runnable {

    static {
        System.out.println("Getting ready to greet the world");
        try {
            Thread t = new Thread(new Lock());
            t.start();
            t.join();
        } catch (InterruptedException ex) {
            System.out.println("won't see me");
        }
    }

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }

    public void run() {           
        Lock lock = new Lock();      
    }

}
