It teaches COBOL programmers how to read and write Java programs and helps them understand the concepts necessary to continue to improve their Java skills. Rather than serve merely as an overview, Java for S/390 and AS/400 COBOL Programmers is a massive work of 800 pages that addresses Javas syntax and much of the Java Development Kits (JDKs) functionality through comparisons with COBOL. It also introduces applets, Java Native Interface (JNI), Remote Method Invocation (RMI), serialization, JavaBeans, Enterprise JavaBeans, servlets, JavaServer Pages, and even Extensible Markup Language (XML). Because VisualAge for Java (VAJ) is by far the most widely used Java tool among AS/400 and S/390 programmers, the book also includes an introduction to VAJ with both AS/400 and S/390 details. The book contains separate appendices, geared explicitly to OS/400 and OS/390 readers, with platform-specific information. Many analysts are predicting that Java will overtake COBOLs commanding lead as the language of choice for business applications running on mainframe and midrange computers. This leaves COBOL programmers with a huge problem. They do not know Java, nor do they understand object-oriented concepts. They have never seen a function, let alone free-form C-style syntax, classes, objects, or methods. Although there are hundreds of books about Java on the market, they all assume C, C++, or Visual Basic knowledge. It can be a humbling, daunting, and frustrating experience for a COBOL professional to try to learnJava without the proper prerequisite knowledge. This book will make learning Java as comfortable as possible.
