将有符号字节转换为“无符号”存储到Harddrive等的字节 [英] Converting Signed byte to "unsigned" byte for storing to Harddrive etc

问题描述

让我们说我正在使用一种文件格式，从0-255获取一些输入的字节。在Java中，使用allways signed byte有点难。



如何将int转换为byte并获得正确的二进制值？

Lets say i am working with a file format that takes bytes from 0-255 for some input. In Java, that is a bit hard with the allways signed byte.

How do i convert a int to byte and get the correct binary value?
