  • Create if and if/else constructs
  • Use a switch statement

4 - CREATING AND USING ARRAYS

  • Declare, instantiate, initialize and use a one-dimensional array
  • Declare, instantiate, initialize and use multi-dimensional array
  • Declare and use an ArrayList

5 - USING LOOP CONSTRUCTS

  • Create and use while loops
  • Create and use for loops including the enhanced for loop
  • Create and use do/while loops
  • Compare loop constructs
  • Use break and continue  

6 - WORKING WITH METHODS AND ENCAPSULATION

  • Create methods with arguments and return values
  • Apply the static keyword  to methods and fields  
  • Create an overloaded method
  • Differentiate between default and user defined constructors
  • Create and overload constructors
  • Apply access modifiers
  • Apply encapsulation principles to a class
  • Determine the effect upon object references and primitive values when they are passed  into methods that change the values

7 - WORKING WITH INHERITANCE

  • Implement inheritance
  • Develop code that demonstrates the use of polymorphism
  • Differentiate between the type of a reference and the type of an object
  • Determine when casting is necessary
  • Use super and this to access objects and constructors
  • Use abstract classes and interfaces

8 - HANDLING EXCEPTIONS

  • Differentiate among checked exceptions, RuntimeExceptions and Errors
  • Create a try-catch block and determine how exceptions alter normal program flow
  • Describe what Exceptions are used for in Java
  • Invoke a method that throws an exception
  • Recognize common exception classes and categories

JAVA SE 7 PROGRAMMER II

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 
  • Use throw and throws statements 
  • 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 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  
  • 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
Threads 
  • 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.
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.
  • Use the parallel Fork/Join Framework
Localization 
  • 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
