Java Programming Language Fundamentals

Course Overview

Students who can benefit from this course are individualswho have basic mathematical, logical, and analytical problem-solving skills and who want to begin learning the Javaprogramming language. These students are encouraged to havehad some programming experience, whether with a scriptinglanguage such as Perl or a third-generation language(such as Basic or C) prior to attending this course.These students include:

• Technical writers, Web developers, technical managers, and individuals with a technical, non-programming background, such as system administrators
• Novice programmers, and those programmers who prefer to start learning the Java programming language at an introductory level

Skills Gained

Upon Completion Of This Course, Students Should Be Able To:

• Demonstrate knowledge of Java technology, the Java programming language, and the product life cycle
• Use various Java programming language constructs to create several Java technology applications
• Use decision and looping constructs and methods to dictate program flow
• Implement intermediate Java technology programming and object-oriented (OO) concepts in Java technology programs

Prerequisites

To succeed fully in this course, students should be able to:

• Create and edit text files using a text editor
• Use a World Wide Web (WWW) browser
• Solve logic problems
• Describe the concept of a variable
• Execute commands using a command-line interface

Course Outline

Module 1 - Explaining Java Technology
