Answer :

Apparently not. Microsoft will never offer a complete Java environment because Sun has essentially required that Java licensees implement all of Java—something Microsoft will never do. (Why should it? Does anyone expect Sun to implement C#, VB.NET, and the .NET Framework?) And if a Java aficionado chooses to use a CLR-based Java compiler, such as the one included with Microsoft's JUMP for .NET technology, she's unlikely to be truly happy. Java implies a series of Java libraries and interfaces, such as Swing and Enterprise JavaBeans. The .NET Framework provides its own equivalent technologies, and so most of these won't be available. As a result, a developer using the Java language on the .NET Framework won't feel like she's working in a true Java environment because the familiar libraries won't be there.
