Java Class Design:
  • Use access modifiers; private, protected, and public; Override methods; Overload constructors and methods; Use the instanceof operator and casting; Use virtual method invocation; Override the hashCode, equals, and toString methods from the Object class to improve the functionality of your class; Use package and import statements
Advanced Class Design:
  • Identify when and how to apply abstract classes; Construct abstract Java classes and subclasses; Use the static and final keywords; Create top-level and nested classes; Use enumerated types
Object Oriented Design Principles:
  • Write code that declares, implements and/or extends interfaces; Choose between interface inheritance and class inheritance; Apply cohesion, low-coupling, IS-A, and HAS-A principles; Apply object composition principles (including has-a relationships); Design a class using a Singleton design pattern; Write code to implement the Data Access Object (DAO) pattern; Design and create objects using a factory pattern
Generics and Collections:
  • Create a generic class; Use the diamond for type inference ; Analyze the interoperability of collections that use raw types and generic types; Use wrapper classes, autoboxing and unboxing; Create and use List, Set and Deque implementations; Create and use Map implementations; Use java.util.Comparator and java.lang.Comparable; Sort and search arrays and lists
String Processing:
  • Search, parse and build strings (including Scanner, StringTokenizer, StringBuilder, String and Formatter); Search, parse, and replace strings by using regular expressions, using expression patterns for matching limited to: . (dot), * (star), + (plus), ?, \d, \D, \s, \S, \w, \W, \b. \B, [], (); Format strings using the formatting parameters: %b, %c, %d, %f, and %s in format strings
Exceptions and Assertions:
  • Develop code that handles multiple Exception types in a single catch block; Develop code that uses try-with-resources statements (including using classes that implement the AutoCloseable interface); Create custom exceptions; Test invariants by using assertions
Java IO 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; Read and change file and directory attributes, focusing on the BasicFileAttributes, DosFileAttributes, and PosixFileAttributes interfaces; Recursively access a directory tree using the DirectoryStream and FileVisitor interfaces; Find a file with the PathMatcher interface; Watch a directory for changes with the WatchService interface
Building Database Applications with JDBC:
  • Describe the interfaces that make up the core of the JDBC API (including the Driver, Connection, Statement, and ResultSet interfaces and their relationship to provider implementations); 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
  • Create and use the Thread class and the Runnable interface; Manage and control thread lifecycle; Synchronize thread access to shared data; Identify code that may not execute correctly in a multi-threaded environment
  • 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; Use the parallel Fork/Join Framework
  • Read and set the locale by using the Locale object; Build a resource bundle for each locale; Call a resource bundle from an application; Format dates, numbers, and currency values for localization with the NumberFormat and DateFormat classes (including number format patterns); Describe the advantages of localizing an application; Define a locale using language and country codes
