More than one jvm present on single processor?

JVM:  java virtual mission. it allocates the memory objects ,variables, etc.

Thread: A thread is a thread of execution in a program. The Java Virtual Machine allows an application to have multiple threads of execution running concurrently.

All threads run in the same JVM. The JVM is capable of running multiple threads on the same processor; some JVMs can even utilize multiple processors by scheduling threads on different processors. But there's still only a single JVM instance.
