Java Developer Training Course (JDTC)

The Java Developer training course provided at Polygon Technologies trains aspiring Java developers in the following core aspects:

• skills need to write the basic Java applications.
• The advanced Object-Oriented concepts, Collections, Logging, I/O streams, Threads and its handling, Sockets, Exception and its handling etc.
• The latest advanced Java 6 specific concepts such as generics, annotations, and reflections.



Objective

To teach attendees about:

• The fundamentals of Java programming and how to use Java to write applications for different requirements
• Implementing and using inheritance and polymorphism, including interfaces and abstract classes.
• The core object-oriented concepts including classes, interfaces, packages, objects, methods, properties, abstraction, polymorphism, inheritance, encapsulation etc.
• Elaborate concept of Exception handling encountered during development in Java.
• The structure of I/O streams in Java, and how to use streams to manage files.
• To use Java Serialization to internalize and externalize potentially complex object graphs.
• To write Thread based (multi-threaded as well) Java applications.
• The use of Reflection API for highly generic tasks, discovery, or code-generation.
• The use of standard Annotations and develop custom annotations to express meta-data in Java source files.
• To communicate between processes using network sockets.



Prerequisites:

This Java Developer training course is personalized for audiences ranging from novice programmers to experienced OO developers (such as in C++ or any other language) seeking to learn Java. Hence this course is useful for beginners as well as for experienced OO developers.
