Java: Concurrent Programming (JAV4)

Programming, Java, Spring

The audiences are supposed to be more experienced. Although the terminology and used concepts (like a thread, race conditions etc.) are repeated briefly as part of the introduction and the starting point, the audiences should have basic understanding for those core concepts.

The course:

Hide detail

• Introduction in concurrency
1. Thread, multithreading, parallel processing
2. Benefits and pitfalls; race conditions, deadlocks, livelocks, performance considerations

• Execution model
1. Execution order, ordering rules, memory visibility
2. Java Memory Model, happens-before relation
3. Exploiting the Java execution model

• Concurrency in theory
1. State management, immutability
2. Confinement and confining techniques
3. Safe publishing

• Concurrency in practice
1. Idioms: double-checked locking, lazy initialization holder, final wrapper
2. Instance pooling
3. Designing a thread-safe class; design considerations and pitfalls

• Basic threading support
1. Monitors: JVM and Java, using intrinsic locks and conditions
2. Threads, blocking, and interruptions
3. JVM shutdown

• Threading framework
1. Thread pools, Executor framework, Fork Join Pool
2. Task-based approach, scheduling, futures
3. Cancellation problem

• Building blocks
1. Light-weight synchronization: atomic variables, volatiles
2. Synchronization primitives: locks, semaphores, barriers, counters, phasers etc.
3. Synchronized and concurrent collections

• Concurrent problems
1. Deadlocks, livelocks, starvation: causes and solutions, techniques
2. Amdahl’s Law, cost of concurrency, performance considerations
3. Common bottlenecks, optimization strategies
4. Non-blocking techniques

• Some other frameworks
1. NIO: non-blocking I/O
2. NIO.2: asynchronous I/O
3. Fork Join Pool, support for asynchronous tasks
