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

C + + and other pure compilation language from the source to the final implementation of the general experience: compile, connect and run three stages, the connection is completed during the compilation, and Java during the compilation is only the Java Virtual machine can recognize the source code class file,

Understanding of the Java Virtual machine stackThe virtual machine stack is the stack memory we know, and the stack memory is unique to the thread. The reference type stored in the local variable table in the stack memory is simply the memory address of the storage object. T

[TOC]OverviewThe virtual machine loads the data of the description class from the class file into the memory, verifies the data, parses and initializes it, and finally forms the Java type that can be used directly by the virtual machine, which is the class loading mechanism

A Java Virtual machine stack contains multiple stack frames, and a stack frame is used to store information such as local variable tables, operand stacks, dynamic links, method

and semantics of the loaded main class, and create static fields of the class or interface and initialize these fields as standard default values, resolution checks the symbolic references of the main class to other classes or interfaces. This step is optional. Class initialization is the execution of the static initialization function declared in the class and the initialization constructor of the static domain. The parent class of a class must be i

Other data types supported by virtual machines include:Object // 4-byte reference to a javaobjectReturnaddress // 4 bytes for the JSR/RET/JSR-W/ret-W commandNote: Java arrays are processed as objects.
