This Course is designed to provide the mainframe developer with a broad overview of the Java object oriented approach. Developers will learn the key elements of object oriented applications including classes, interfaces, attributes, objects, access levels, inheritance and polymorphism. The instructor will make comparisons with mainframe legacy development to facilitate the learning process. Suitable for: This Course is aimed at mainframe developers, already experienced with languages such as COBOL or PL1, who need to be cross-trained to understand Object Orientation and write Java programs.

Course Objectives
This Course is designed to provide the mainframe developer with a broad overview of the Java object oriented approach. Developers will learn the key elements of object oriented applications including classes, interfaces, attributes, objects, access levels, inheritance and polymorphism.

The instructor will make comparisons with mainframe legacy development to facilitate the learning process.

This Course also provides students with the skills to write simple Java programs. The syntax of the language is covered in detail and also Object Oriented coding techniques are discussed.

During the Course the student will write many applications to ensure that the concepts and statements taught are fully understood and practical experience is gained.

The Course is taught using a choice of IDE. The skills needed to use this software are presented as part of the Course.

On completion of this Course the student will be able to:

  • Understand the concepts of object oriented programming
  • Understand and differentiate between objects and classes
  • Understand object instantiation
  • Understand and differentiate between instance methods and variables and class methods and variables
  • Understand the concept and benefits of messaging
  • Understand the concept and benefits of encapsulation
  • Understand the concept and benefits of inheritance
  • Understand the concept and benefits of interfaces
  • Understand the concept and benefits of polymorphism
  • use the major concepts of a modern, block-structured, high-level language, such as control flow, function calls and modular programming
  • structure programs using classes and other essential object-oriented features
  • create, test and debug simple Java code using the chosen Integrated Development Environment (IDE)

Course Format: Practical sessions make up a large part of the course, allowing delegates to demonstrate and reinforce the lectures given. During these sessions the delegate will build a simple but complete application. Examples are used extensively, ranging from simple code 'snippets' to full applications with complete 'real world' functionality. These are supplied at the start of the course and it is encouraged that the delegates execute and 'experiment' with these under the instructor's guidance as they are introduced. These examples are available to take away, along with the delegate's own work. The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
