Structure of class fileThere are two structures in Java's class file: unsigned numbers and tables. The smallest storage unit is 8 bytes.Unsigned numbers are the basic data types used to describe numbers, UTF-8 encoded strings, and index references.Represents a complex data structure that consists of multiple unsigned numbers.which Magic is the magic number, and the magic number takes up 4 bytes, what is the magic number to do? It actually means that the type of the file is a class file, no
