Parallelization between .Net with Java technology platform

.Net and Java are both mist popular development technology platform currently. However, both have been evolving in parallel. If something comes out in Java .Net is quick to adopt it in itself. Similar, good practices of .Net are also embraced by Java Community.

I would not rate any one over the other. Both have a place and are usually selected based on the requirements and constraints. Constraints could be speed, interoperability, mix of technologies, rich user interface, preferred technology by my customer, existing skill level, existing code etc.

I will try to list equivalent components of Java and .Net with a caveat. 

Description	Microsoft	Java
Languages:	C#, VB.Net, J# etc. .Net with its CLS,CTS  specification allows any language to achieve .Net compatible.	Java
Infrastructure to develop and run the components. (Libraries for security, garbage collection and runtime)	CLR  - (Common Language Runtime) CTS, CLS, CIL: provides support for multiple and intra – language development. VES – Virtual Execution System	JVM – Java Virtual Machine
