23.4.2. Intrinsic Locks and Monitors

Try these first

1. 1.

   What is an intrinsic lock in Java?

   Hint

   Think about thread access to methods.

2. 2.

   What is the purpose of monitoring in thread synchronization?

   Hint

   Consider what happens when one thread uses a method.

3. 3.

   What is an intrinsic lock?

   • A feature of class inheritance
   • A mechanism ensuring mutually exclusive access
   • A Java collection type

   Hint

   Think about what synchronization helps achieve.

4. 4.

   True or False: A monitor allows multiple threads to execute synchronized blocks simultaneously.

   • True
   • False

   Hint

   Consider the purpose of mutual exclusion.

5. 5.

   Write a Java program that demonstrates thread synchronization using intrinsic locks. Explain any issues you encounter and potential solutions.

   Hint

   Focus on demonstrating what happens with and without synchronization.

6. 6.

   Discuss the case of a deadlock in a hypothetical program using intrinsic locks. How would you prevent this issue?

   Hint

   Consider two threads waiting on each other's locks.
