Why Java OutputStream.write() Takes Integer but Writes Bytes

The documentation for FileOutputStream.write(int b) states that it writes the byte to the file, but the argument is an integer. Could someone please clarify?

Was it helpful?

Solution

It writes the least significant byte of the int argument to the file.

OTHER TIPS

It actually only writes the lowest order byte from that int. This was actually debated before: Why does the write(int b) method of OutputStream exist?
