How do you get a new thread to execute its run method?

• This automatically happens when you create the thread.

• Call .start() on the thread.

• Call .run() on the thread.

• Call .start() on the thread, then call .run().

When is the JVM terminated (i.e., when does a Java programm "end")?

• When the main thread finishes executing.

• When all non-daemon (user) threads finish executing.

• Whenn ALL threads finish executing, including daemon (non-user) threads.

What is the problem with the following code?

• There is no problem.

• The nested class MyThread needs to be static.

• The class is defined above the main method.

• The nested class MyThread can't be public.

How are instructions of different threads interleaved?

• The thread first created finishes executing, then the second thread, etc.

• The threads execute one instruction each, taking turns in order of creation.

• Randomly, but no thread executes two instructions in a row if others "wait".

• Randomly, there are no guarantees.

Will this compile and run without a problem?

• No, the threads are not joined.

• Yes.
