Tut5	ReentrantReadWriteLock: NewsArticle, PatientMonitor
Tut6	Semaphore: StudyRoomKey, FoodManager
Tut7	Thread pools with ExecutorService: Q1 student marks calculation, Q2 support request processing

Concepts covered

• Thread, Runnable, start() vs run()
• ExecutorService and thread pools
• Callable and Future
• ThreadFactory and scheduled tasks
• ReentrantLock and Condition
• Semaphore
• ReentrantReadWriteLock
• Producer-consumer and race conditions

How to run

javac -d out src/Tut5/*.java
java -cp out Tut5.PatientMonitorMain

Requires JDK 8 or later. Each folder under src is a package, so swap Tut5 and the class name for any other exercise. For Tut7, the exercises are in subfolders, for example:

javac -d out src/Tut7/Q2/*.java
java -cp out Tut7.Q2.SupportRequestMain
