A long bigger than Long.MAX_VALUE

How can I get a long number bigger than Long.MAX_VALUE?

I want this method to return `true`:

``````boolean isBiggerThanMaxLong(long val) {
return (val > Long.MAX_VALUE);
}
``````

That method can't return `true`. That's the point of `Long.MAX_VALUE`. It would be really confusing if its name were... false. Then it should be just called `Long.SOME_FAIRLY_LARGE_VALUE` and have literally zero reasonable uses. Just use Android's `isUserAGoat`, or you may roll your own function that always returns `false`.

Note that a `long` in memory takes a fixed number of bytes. From Oracle:

long: The long data type is a 64-bit signed two's complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). Use this data type when you need a range of values wider than those provided by int.

As you may know from basic computer science or discrete math, there are 2^64 possible values for a long, since it is 64 bits. And as you know from discrete math or number theory or common sense, if there's only finitely many possibilities, one of them has to be the largest. That would be `Long.MAX_VALUE`. So you are asking something similar to "is there an integer that's >0 and < 1?" Mathematically nonsensical.

If you actually need this for something for real then use `BigInteger` class.
