how to declare a long long array in Java?

Question

A simple question: Can someone help me declare a long long array in Java? I've tried to cast it, but no luck:

(long long)[] sum = new (long long)[10];

Also, I searched across the internet and didn't really find anyone who uses long long to define an array Any help please?

"I know for one variable, we can just declare it to be (long long) var;" are you sure about it? Which part of tutorial/specification makes you think it should be OK to use `long long` in Java? — Pshemo, May 16 '16 at 16:16

That page mentions multiple languages - the sample code is *not* Java. — Jon Skeet, May 16 '16 at 17:37

I do not know a type called "long long".

Are you sure the code you read was written in Java? Maybe it was a JNI routine that was called into?

There is no long long type in Java.

If you need an arbitrarily-long integer type, you can use BigInteger, but this is a reference type, and has no "convenient" operators like +.

long long is not a valid type in java

using a big integer would make more sense in this case...

BigInteger[] sum = new BigInteger[10];
