About this page

Java multithreading (fresher level) introduces concurrency. This module is an elevation arc: it opens with thread basics and the lifecycle (NEW → RUNNABLE → TERMINATED), then creating threads and thread vs Runnable. Synchronization follows at the mechanics tier, then the concurrency problems (race conditions, deadlock) a fresher must recognize. The volatile keyword and wait/notify close the module at the coordination tier.
