1. Concurrent Programming Concepts
2. Threads
• Threads versus processes
• Runnable versus Thread subclass
3. Java Support for Concurrency
• Threads : either inherit from Thread class or implement Runnable interface
• Synchronized : specifies critical section using an object as lock
• Locks are reentrant
• Locks can be temporarily given up : wait and notify
4. Even-odd transposition algorithm
5. Distributed Applications
• Channels (send/receive)
• Distributed objects (RPC/RMI)
• Middleware agent (space/message queue)
6. Patterns
   • General concept
   • Prototype (cloning)
   • Bridge (delegate)
   • Decorator (filtering)
   • Observer
   • Bean
7. Java Event Model
   • Listeners
   • Single event thread in Java and implications
8. Model View Controller
   • Why and what?
9. Component Assembly
   • Java Beans
   • Serialization
   • Introspection
   • Property editors
   • Wiring of Events to Listeners
10. Security
    • Fundamental properties
      • privacy
      • integrity
      • authentication
      • non-repudiation
    • Symmetric/secret key
    • Asymmetric/public key
    • Key agreement protocols
    • Key management
    • Hash functions to create digest
    • Digital Signatures
    • timstamping to limit repudiation
11. Databases
    • Relational concepts
    • tables, nrows, columns
    • primary key
    • SQL
      • selection
      • selection criteria
    • Optimization of relational queries
    • JDBC:
      • The process
        • get a Connection -- may involve name, password
        • create a Statement (or several)
        • execute a query -- returns a ResultSet
        • if necessary, get ResultMetaData
          • can tell you number of columns, column classes, etc.
        • process resultSet using next() method (must start with next())
        • can access columns by name or number (faster)
      • PreparedStatement
      • CallableStatement
      • Updatable ResultSet properties (if available)
    • Transactions
      • transaction makes a series of SQL statements appear to be atomic
      • auto commit -- close commits
      • commit or rollback before close
      • ACID
        • Atomicity - The entire sequence of actions must be either completed or aborted. The transaction cannot be partially successful.
        • Consistency - The transaction takes the resources from one consistent state to another.
        • Isolation - A transaction's effect is not visible to other transactions until the transaction is committed.
        • Durability - Changes made by the committed transaction are permanent and must survive system failur
      • The above properties are critical to transaction semantics
