2. Thread Pools

• Fixed thread pools
• Cached thread pools
• Single thread executors
• Scheduled executors

3. Synchronization

• Race condition demonstration
• Synchronized methods and blocks
• Volatile keyword usage
• Lock mechanisms

4. Producer-Consumer Pattern

• BlockingQueue implementation
• Multiple producers and consumers
• Thread coordination

5. Concurrent Collections

How to Run

Compile the project:

javac -d . src/main/java/com/multithreading/**/*.java

Run the main application:

java com.multithreading.MultithreadingMain

Run individual examples:

java com.multithreading.examples.ThreadExample
java com.multithreading.examples.Thread_Beispiel

Requirements

• Java 8 or higher
