What is Java long long long

Question

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

However, I recently met some Java code using "long long" and wanted to know how exactly it was defined?

Answer 1

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

Answer 2

I do not know the type of "long long".

it is also not listed here: http://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html

Answer 3

"long long" is not supported in java

Answer 4

Support INT-16bit
long 32bit
to calculate a large number, you can use both long and int.
