Java Multithreading - Quick Revision for Interviews || The Ultimate Interview Guide | Java In Action

Topic Navigation Introduction & Basics • – Introduction: What is Multithreading? • – Thread vs. Process & Shared Memory • – CPU-bound vs. IO-bound tasks Thread Creation • – The 4 Ways to Create Threads (Overview) • – Method 1: Extending Thread (Legacy) • – Method 2: Implementing Runnable (Composition over Inheritance) • – Method 3: Callable & Future • – Method 4: ExecutorService (Modern Best Practice) • – Interview Question: start() vs. run() Thread Lifecycle • – The Thread Lifecycle Map • – States: New, Runnable, Terminated • – The Waiting States: Blocked, Waiting, Timed_Waiting • – Interview Question: sleep() vs. wait() Scheduling & Priority • – Thread Scheduling & The OS • – Thread Priority (Why it is just a "hint") Synchronization • – Synchronization & Race Conditions • – The "Traffic Cop" Analogy (Mutual Exclusion & Visibility) • – Synchronized Blocks vs. Methods • – Interview Question: Can you synchronize a constructor? Inter-Thread Communication • – wait(), notify(), and notifyAll() • – Spurious Wakeups (Why we use while loops) • – The Producer-Consumer Problem • – Solution: BlockingQueue Concurrency Issues • – Deadlock (The Circular Wait) • – Livelock (Active but making no progress) • – Starvation (Unfair resource allocation) Memory & Safety • – The volatile Keyword (Visibility problem) • – Volatile vs. Atomicity • – Atomic Variables & CAS (Compare-And-Swap) • – The ABA Problem Locks & Executors • – synchronized vs. Lock Interface • – ReentrantLock & Fairness • – ReadWriteLock • – The Executor Framework • – Thread Pools (Fixed, Cached, Single, Scheduled) • – Rejection Policies (e.g., CallerRunsPolicy) Advanced Tools • – Fork/Join Framework & Work Stealing • – Parallel Streams (and the Common Pool trap) • – CompletableFuture (Async Pipelines) • – thenApply vs. thenCompose • – Immutability & Thread Safety • – Daemon Threads vs. User Threads Java Multithreading, Concurrency, Thread vs Process, Runnable Interface, Callable and Future, ExecutorService, Thread Lifecycle, Sleep vs Wait, Thread Scheduling, Race Conditions, Synchronized Keyword, Inter-thread Communication, Spurious Wakeups, Producer Consumer Problem, BlockingQueue, Deadlock, Livelock, Starvation, Volatile Keyword, Java Memory Model, Atomic Variables, CAS Algorithm, ReentrantLock, ReadWriteLock, Fork Join Framework, Parallel Streams, CompletableFuture, Async Programming, Immutability, Daemon Threads, Garbage Collection, Thread Safety, Java Interview Questions #Java #Multithreading #Concurrency #JavaInterview #ExecutorService #CompletableFuture #ThreadSafety #Synchronization #RaceCondition #Deadlock #Volatile #AtomicInteger #ForkJoin #ParallelStreams #Immutability #DaemonThreads #BlockingQueue #ReentrantLock #SystemDesign #BackendDevelopment #SoftwareEngineering #CodingInterview #Java8 #AsyncProgramming
