Java Basic Syntax:1): The Java language is strictly case-sensitive, like main and main are completely different concepts. 2): Multiple Java classes can be defined in a Java source file, but at most one of these classes is defined as the public class.

Communication between programs is actually sending and receiving data streams. We generally regard bytes as the smallest unit of data. Of course, a byte also contains 8 bits ). In a 32-bit processor, the "font length" is 32 bits, that is, 4 bytes.
