Project Ideas

  1. Multi-threaded Web Crawler - Practice concurrency, thread pools
  2. Concurrent Chat Server - Use sockets, ExecutorService, synchronization
  3. JVM Memory Analyzer Tool - Parse heap dumps, analyze GC logs
  4. Performance Benchmarking Framework - Profile different implementations
