transient: indicates that the member of the class need not be serialized during serializatin process (hence need not be restored during dererialization)

volatile: indicates that the member variable is accessed by multiple threads simultaneously and certain optimizations should not be allied for it.See Java Memory Model for detailed info.

Did you try Google? Searching for "java transient" or "java volatile" will give you a lot of information very quickly.
