  • Format strings using the formatting parameters: %b, %c, %d, %f, and %s in format strings.
Exceptions and Assertions

Java I/O Fundamentals 
  • Read and write data from the console
  • Use streams to read from and write to files by using classes in the java.io package including BufferedReader, BufferedWriter, File, FileReader, FileWriter, DataInputStream, DataOutputStream, ObjectOutputStream, ObjectInputStream, and PrintWriter
Java File I/O (NIO.2) 
  • Operate on file and directory paths with the Path class 
  • Check, delete, copy, or move a file or directory with the Files class

  • Identify the components required to connect to a database using the DriverManager class (including the jdbc URL)
  • Submit queries and read results from the database (including creating statements, returning result sets, iterating through the results, and properly closing result sets, statements, and connections)
  • Use JDBC transactions (including disabling auto-commit mode, committing and rolling back transactions, and setting and rolling back to savepoints)
  • Construct and use RowSet objects using the RowSetProvider class and the RowSetFactory interface
  • Create and use PreparedStatement and CallableStatement objects
Threads

  • Manage and control thread lifecycle
  • Synchronize thread access to shared data
  • Identify code that may not execute correctly in a multi-threaded environment.
Concurrency 
  • Use collections from the java.util.concurrent package with a focus on the advantages over and differences from the traditional java.util collections.
  • Use Lock, ReadWriteLock, and ReentrantLock classes in the java.util.concurrent.locks package to support lock-free thread-safe programming on single variables.
  • Use Executor, ExecutorService, Executors, Callable, and Future to execute tasks using thread pools.

Localization 
  • Read and set the locale by using the Locale object
