SUMMARY:   This course provides an introduction to the Java programming language using a client-side application context. Java programming syntax, fundamental APIs and OO syntax and principles are covered. File I/O, Database processing, Thread, Networking and GUI packages are included. AUDIENCE:   The material covered in this course is designed for students with previous C-based and OO programming experience who plan to develop programs using Java. PREREQUISITES:   Students should have previous OO programming experience in languages such as C++, C#. A strong VB background is also sufficient. Students without a C/OO background should consider attending "Java Fundamentals for Non OOP and Cobol Programmers". DURATION:   5 Days APPROACH:   Instructor-led lecture and discussion with extensive demos and hands-on labs. Chapter appendices include optional/advanced material. Several optional closing topics are available to be included as time permits. Multiple labs for each chapter allow students with varied backgrounds to progress through the material. OBJECTIVES:   At the end of this course, students will be able to: Describe the evolution of Java releases and SE/EE API facilities. Understand the JVM and its provision of application portability. Develop console-based client-side applications using the full core Java syntax. Understand and code for runtime exception handling. Write programs using existing classes in the Lang and Util Java packages. Write programs to access disk-based file sources using the Java IO package using byte, binary, character and object streams. Write programs to manipulate relational databases using the Java SQL package including Basic/Advanced ResultSets, Stored Procedures and Transaction Management. Develop desktop GUI programs including component event handling using the AWT and Swing packages Understand the OO principles of abstraction, encapsulation, polymorphism and inheritance. Develop and use individual custom application classes following the JavaBean design pattern. Understand and utilize classes employing inheritance; Extend existing classes, provide constructors and override methods. Understand the usage of Threads and develop Threaded applications. Understand network programming and develop Socket-based client-server applications.
