Java Programming: A Comprehensive Hands-On Introduction

Frequently Asked Questions

What is Java? Java is an object-oriented programming language. Java is in the same family as C and C++ and solves many of their complexities (pointers, memory allocation, multiple inheritance, etc.). Java is also a portable language, and compiled Java programs run without recompilation on Macintosh, Microsoft Windows, UNIX and other platforms. Java is a mature language that can be used to write entire standalone or server applications. Java has become the dominant platform for modern software development for reasons of reliability, maintainability and ease of development. What background do I need? This course is for programmers with hands-on experience in a modern programming language such as C, Pascal or COBOL. You should have three to six months' experience in a high-level programming language before attending. You should know how to: Structure data Use variables, flow-control statements and subroutines Write, compile and execute a program Experience with professional programming is assumed. Non-programmers should take Course 487, Designing and Building Great Web Pages: Hands-On. If you are interested in learning JavaScript or JScript, you can take Course 489, JavaScript for Web Development: Hands-On. Who will benefit from this course? This course provides a solid introduction to programming in Java and is useful for programmers, engineers, analysts and managers. Those who would benefit include: Application developers intending to use Java to build applications Developers interested in learning the basics of Java before beginning work with a visual development environment (e.g., JBuilder, IBM WebSphere Studio) I have designed Web pages in HTML. Is that adequate preparation for this course? No, HTML is not enough. Experience writing several large Web sites in CGI and Perl is sufficient. Otherwise, experience in a programming language such as C, Pascal or Visual Basic is necessary. Does this course use Sun's development tools, the JDK or any IDEs? This course uses Sun's Java 2 SDK, Standard Edition (J2SE). This course also uses the Eclipse Java IDE. The concepts you learn in the course will also work in Borland JBuilder, IBM WebSphere Studio and other Java IDE tools. Does this course cover JavaScript? JScript? No. JavaScript is a scripting language, useful to system administrators and Webmasters, to enhance some aspects of Web pages. JavaScript shares some features of Java but is not directly related. JScript is Microsoft's implementation of a JavaScript-like language. Neither JavaScript nor JScript are covered in this course. You can, however, take Course 489 to learn JavaScript and JScript. How much time is devoted to each topic? Content Hours Introduction 1.0 Object-oriented programming 2.5 Structure of the Java language 3.5 Java classes and interfaces 5.5 Developing GUI applications 6.5 Input and output 3.0 Times, including the workshops, are estimates; exact times may vary according to the needs of each class. What are the hands-on exercises? Exercises include: Developing an object-oriented model with UML notation Creating Java objects and calling their methods Building Java classes and subclasses Building a GUI using the Java Foundation Classes Reading and writing a file to disk Are Microsoft extensions to Java covered? No, instead the course concentrates on the standard Java features that work in all development environments and in all Java runtimes. Why should I take this course instead of one offered by Sun Microsystems? Learning Tree is dedicated to helping accelerate the careers of our clients by providing them with world-class technology and management training. Our independence from Sun Microsystems (and any other vendor) allows us to give an unbiased view of what works and what does not. This course is objective in its approach, having been developed independently from Sun by industry experts who bring real-world experience to the classroom. What systems and software are used with this course? Although our normal classroom setup uses PCs running Windows Server 2003 with the latest Microsoft and Netscape browsers, everything you learn about Java applies equally to UNIX, Macintosh, Windows, OS/2 and other operating systems. How does this course relate to other Learning Tree courses?
