Concurrent Programming Concepts and Examples

This ticket-booking code have set of Java examples that demonstrate various locking mechanisms. These examples are designed to illustrate how concurrency and synchronization are handled in Java applications.

Implemented Concepts:

ReentrantLock

• lock.lock():

  • Acquires the lock, blocking until it's available.

• lock.lockInterruptibly():

  • Acquires the lock unless the current thread is interrupted.

• lock.tryLock(1, TimeUnit.SECONDS):

  • Attempts to acquire the lock, waiting up to 1 second before giving up.

synchronized Keyword

• synchronized Keyword:
  • Illustrates the behavior of the synchronized keyword in Java.

Source Code Structure:

To facilitate understanding, I've organized the examples into different packages, each focusing on a specific locking mechanism:

• org.example.ex1: Demonstrates the use of lock.lock().
• org.example.ex2: Illustrates the behavior of the synchronized keyword.
• org.example.ex3: Shows examples using lock.lockInterruptibly().
• org.example.ex4: Highlights the usage of lock.tryLock(1, TimeUnit.SECONDS).

Instructions:

To observe the output of each example, run the Main class located in each respective package. This will execute the demonstration specific to that locking mechanism.
