Question about the task

The whole world is a comedy

Java Multithreading, Level 6, Lesson 10

Under discussion

This code passed, but it makes no sense to my and I didn't understand anything.

public void someMethod() {
    // Implement the logic here. Use the lock field
    lock.tryLock();
    if(lock.tryLock())
        lock.unlock();
    lock.lock();

    actionIfLockIsBusy();
    actionIfLockIsFree();
}

My solution:

public void someMethod() {
        try {
            if (lock.tryLock()) {
                actionIfLockIsFree();
            } else {
                actionIfLockIsBusy();
            }
        } finally {
            if (lock.tryLock())
                lock.unlock();
        }
    }

I think is more understandable
