Why is this Java long overflowing? [closed]

Question

This is very weird.

A class I wrote has the following data member:

final static long MAX_FILE_SIZE_BYTES = 50000000000L;

at one point in my code the following block is run

System.out.println("MAXFILESIZEBYTES: " + MAX_FILE_SIZE_BYTES);

and the output is:

MAXFILESIZEBYTES: -1539607552

My question is, why is this long value overflowing? Java is supposed to be machine independent, and longs are supposed to hold 64 bits. What gives?

Answer 1

Cannot reproduce.

50000000000L is 0x0000000BA43B7400.

-1539607552 is FFFFFFFFA43B7400, which is what you would get if you cast the value to int.

Ergo somewhere you are casting it to int. Maybe you have a shadowed variable.
