tabbed panes, desktop panes, internal frames (containers)
GridBagLayout
BoxLayout features (struts, glue, etc)

Multithreading

Know the basic concepts of processes and multitasking
Know the difference between running processes concurrently and threading (running threads concurrently)

- thread pools (understand the Executors methods newCachedThreadPool() and newFixedThreadPool(), and the difference between them)
Understand synchronization -- why and when it's needed
- Understand mutual exclusion and locks
- keyword synchronized and built-in monitors for objects
  - includes Object class methods wait(), notify()

  - interface java.util.concurrent.locks.Lock
    - lock()
    - unlock()
  - Condition variables, interface Condition
    - await()
    - signal()
    - signalAll()
- Deadlock

Know how to create a URL object
Know the basics of opening a web page from an applet or application

Understand the process that a client and server must use to set up connection-oriented sockets
- class ServerSocket -- for listening for connections
