Avoiding Deadlocks and Race Conditions

Prevent deadlocks, races, and visibility bugs in Java by designing safer shared-state boundaries before adding more synchronization.

Concurrency failures are often design failures before they are syntax failures. Deadlocks, races, and memory-visibility bugs usually come from unclear ownership, inconsistent lock ordering, or too much shared mutable state rather than from one missing keyword.

This section focuses on prevention first. The goal is to make concurrency bugs structurally less likely through lock discipline, simpler coordination models, and better observability.

The child pages cover practical defensive habits and deadlock detection so you can reason about both design-time prevention and runtime diagnosis.
