Similarities: Java & .NET • • • • • • •

Platform independence . Compile once run any where. Runtime required. Focuses Object oriented programming. Open source and free to use. Intermediate code generation. Runtime compilation.

Differences: Java & .NET • Java the only language, where as .NET languages. • Java is available for all OS, .NET only for Windows. • Introduced concept of web services. • Cross language integration.
