Long is showing up as negative. Why?

[LucL]

I feel silly asking this but I am not sure what the problem is.

long max_daily_bytes2 = 10 * (1024 * 1024 * 1024);
System.out.println(max_daily_bytes2);

Output:

-2147483648

What's causing this? Java longs should have a range of up to 9,223,372,036,854,775,807

Thanks!

Because the numeric literals are default ints in Java. Try someting like this:

long max_daily_bytes2 = ((long) 10) * (1024 * 1024 * 1024);

 

[stefanwagner]

a bit shorter with postfix L:

long max_daily_bytes1 = 10 * 1024 * 1024 * 1024L;
