Solve concurrency in Java evaluates algorithm design, data structures, correctness, complexity, edge cases, and implementation details in a realistic interview setting. A strong answer states assumptions, handles edge cases, explains trade-offs, and shows how to validate the result clearly.

How do you handle concurrency in Java? Compare threads, the Executor framework, synchronized blocks, explicit locks, atomic variables, concurrent collections, and futures/CompletableFuture. Explain techniques to avoid race conditions, deadlocks, and starvation, with examples.
