The java 2 SDK, Standard Edition, contains two implementations of the Java Virtual Machines.
1. Java HotSpot Client VM.
2. Java HotSpot Server VM.

The Java HotSpot Client VM is the default virtual machine of the Java 2 SDK and Java 2 Runtime Environment. As its name implies, it is tuned for best performance when running applications in a client environment by reducing application start-up time and memory footprint.
