Java Training Overview
This course teaches programming in the Java language -- i.e. the Java Standard Edition platform. It is intended for programmers with experience in languages other than Java, but who may or may not have any previous Java experience. It focuses on procedural and structured coding skills first, and then offers meticulous, 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 from these basic skills into key parts of the Java SE Core API, including collections and logging, and introduces features of functional programming, new to the language as of Java 8, including functional interfaces, lambda expressions, and streams.
This revision of the course targets the Java 8 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. To read more about different versions of Java and for help deciding on which version of this course to use, see "Java Versions and Terminology Demystified"
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, “Introduction to Java Programming,” for a more relaxed pace through the early material.
Java Training Prerequisites
No prior Java experience is required, but students must be experienced programmers in another third-generation (high-level) language. See the overview for suggestions about pace and scope for different backgrounds.
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.
- Use Java as a functional language, making appropriate choices of tools including inner classes, functional interfaces, method references, and lambda expressions.
- Use the Stream API for efficient processing of data sets.
