Introduction to Concurrency

• Understanding concurrent programming and its challenges
• Concurrency vs. Parallelism
• Importance of thread safety and synchronization

Threads and Runnable

• Creating and managing threads in Java
• Thread states and lifecycle in Java
• Implementing the Runnable interface

Synchronization and Locking

• Synchronized keyword and intrinsic locks in Java
• Critical sections and mutual exclusion in Java
• Thread interference and memory consistency in Java

Thread Safety

• Designing thread-safe classes and methods in Java
• Atomic operations and the java.util.concurrent.atomic package
