Hello everyone,

I am wondering what is the differences between Java HotSpot(TM) Client VM and the J2SE VM I downloaded from

Are they the same thing? Why Hotspot VM has client and server version?

thanks in advance,

Yes, they are the same thing. Sun has shipped the Hotspot JVM since... well, sometime around Java 1.3, give or take, not sure.

The difference between the client and server version is based on what it does. The client version is designed to run on a smaller footprint, start faster, and for GUI based applications. While the server version is for better overall throughput.
