I am using a JProgressBar to represent the total number of bytes being downloaded when grabbing multiple files from a server.
However, during the calculation of the total number of bytes, which is what I use for the max value of the JProgressBar, the value goes outside the range of the 'int' datatype, which will wrap around and possibly give a negative number, breaking the JProgressBar or at the very least, providing an inaccurate value.
What's the best way to solve this problem of the max range being too high?
Should I just covert my bytes to megabytes, which will lose a bit of precision in the progress calculation? Or, if I want to keep the precision of number of downloaded bytes vs the total number to download, how can I get an accurate % to display in the JProgressBar using the long values?

Seems like the best way is to use a simple % calculation of the long total value vs the current value and then call the setString method on the progress bar.
