Java SE7 Programming Courses

Java Programming Courses in Cape Town


International Java exam: 1Z0-804

2KO presents Java courses in Cape Town. The Oracle Certified Professional (OCP) Java SE 7 is a more advanced certification than ever before. It not only builds on all of the competencies incorporated into our new OCA Java SE 7 certification, but also includes new, advanced skills required of top-performing Java programmers. As a result of its new depth, the OCP Java SE 7 certification now requires you to hold the Associate level Java certification before you can achieve your OCP credential. Certified Java Associates can pursue the OCP certification by completing exam 1Z0-804. 2KO presents Java courses in Cape Town by means of full time instructor-led training; as well as internet-accessible online training, which are aimed at International IT Certification exams. 2KO is an IT consulting and training company, offering both business services and multi-platform training. 2KO Africa's wide range of computer courses are available as full time classes, or as online learning, enabling 2KO students the opportunity to study courses online world-wide, to ensure students have access to the best training possible.



Course outline:
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 package (including BufferedReader, BufferedWriter, File, FileReader,
FileWriter, DataReader, 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 multithreaded 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 lockfree 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
