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
