When viewed as a whole, the Java and .NET class libraries provide comparable functionality. However, as this book has shown, the implementation specifics and structure can often be quite different. This appendix provides a quick reference to Java-to-.NET class library functionality.
We structure the cross-reference at the class level; we exclude interfaces unless they’re essential to understanding the relationship between Java and the Microsoft .NET Framework. Each commonly used Java type from the major packages is listed. We map each Java type to one or more .NET types that provide the same or similar functionality.
The .NET Windows Forms system provides a smaller class set than the Abstract Window Toolkit (AWT) for constructing client applications. See Chapter 18, for more information about the Windows Forms system. The mapping between the Java java.awt package and the corresponding .NET classes is provided in Table F-1.
