What exactly is Java type long long

I know in Java that "int" is a 32 bit integer and that "long" is a 64 integer. I also know that in C "long long" is an integer at least as large as "long" (but implementation specific).

However I have recently come across some Java code using "long long" and wanted to know how exactly it was defined?

There is no such type in Java. Are you sure the code you read was written in Java? Maybe it was a JNI routine that was called into?
