J#

This book aims to explain the role, usefulness and functionality of Microsoft's J# language and class libraries. The objective is to cover the ways J# can be used as a migration tool for Java programmers and Java code, a way of accessing class libraries similar to those provided by Java from .NET, and a way of programming .NET in a different language. J# is Microsoft's .NET upgrade of the J++ concept. J++ was a system that allowed developers to write COM-based Windows applications in the Java language, using a subset of the classes provided by the Java 1.1.4 platform. J# updates this to the .NET system, and provides a way to use the Java language and classes in the .NET environment. Programmers can develop ASP.NET web sites, web services, and Windows applications, using the J# language's Java-like syntax. This book is primarily Aimed at developers curious about J#, what it can and can't do, and in what circumstances it might be useful. Readers may be experienced in Java, or come from an entirely Microsoft/.NET background.
