Java Training Overview
This course teaches programming in the Java language -- i.e. the Java Standard Edition platform. It is intended for students with previous Java experience or training, who already know the fundamentals of the Java architecture and basic procedural programming. This course provides in-depth coverage of object-oriented concepts and how to apply them to Java software design and development. The latter part of the course moves key parts of the Java SE Core API, including collections, exception-handling, logging, streams, and object serialization. The course software also includes an optional overlay of workspace and project files to support use of the Eclipse IDE in the classroom. (This requires that the instructor be experienced in use of Eclipse and able to walk students through basic tasks in the IDE.)
This revision of the course targets the Java 7 language and Core API. See our course catalog for training explicitly geared to earlier versions of Java, going back as far as J2SE 1.4.2.
Students come to Java from a wide range of backgrounds, and this course is designed to be as flexible as possible over the upper end of that range. Specifically:
- Experienced C and C++ programmers will find this course a very good fit and if anything will find that they complete it in a little less than the full five-day timeline.
- Those with experience in languages less like Java, such as Visual Basic, ASP and other Web-scripting languages, and other pseudo-object-oriented languages may need more time in the early going, and this course covers its introductory topics in good depth and offers many optional and "challenge" labs to support this.
- Less experienced programmers or those coming from non-structured languages -- such as COBOL, PL/1, or 4GL tools -- will probably not cover the whole course in a week, and may want to pursue an abbreviated version at a slower pace. This too is quite feasible, but this audience may also want to consider our Course , "Introduction to Java Programming," for a more relaxed pace through the early material.
Java Training Prerequisites
- Students must be able to write, compile, test, and debug simple Java programs, using structured programming techniques, strong data types, and flow-control constructs such as conditionals and loops.
Java Training Learning Objectives
- Chiefly, learn to program effectively in the Java language.
- Understand the Java software architecture, and the design decisions which make Java software portable, efficient, secure and robust.
- Learn how to configure a simple Java development environment.
- Know the grammar, data types and flow control constructs of the Java language for simple procedural programming.
- Understand Java as a purely object-oriented language, and implement software as systems of classes.
- Implement and use inheritance and polymorphism, including interfaces and abstract classes.
- Design appropriate exception handling into Java methods, and use the logging API appropriately.
- Understand the structure of streams in Java, and learn how to use streams to manage file I/O.
- Learn how to use Java Serialization to internalize and externalize potentially complex graphs of objects.
- Build unit tests for Java classes using JUnit.
