This article shows you how JAVA and JVM work respectively. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

How JAVA and JVM work

The source program written in the Java language is compiled into a platform-independent bytecode program (.class file, that is, the 0L1 binary program) through the Java compiler, and then interpreted and executed in the Java interpreter on top of OS, while JVM is the core and foundation of java, the virtual processor between the java compiler and the os platform.

How JAVA and JVM work

The process of running 1.Java language

The source program written in the Java language is compiled into a platform-independent bytecode program (.class file, that is, the 0L1 binary program) through the Java compiler, and then interpreted and executed in the Java interpreter on OS.

It is also quite similar to

Note: JVM (java virtual machine) includes an interpreter. Different JDK virtual machines are the same, but different interpreters are different.

2.JVM:

JVM is the core and foundation of java, a virtual processor between java compiler and os platform. It is a kind of abstract computer implemented by software method based on the lower operating system and hardware platform, on which the bytecode program of java can be executed.

The java compiler only needs to target JVM to generate code or bytecode files that JVM can understand. The Java source file is compiled into a bytecode program, and each instruction is translated into different platform machine code through JVM, which is run on a specific platform.

The process by which JVM executes the program:

i. Load. Class file

ii. Manage and allocate memory

iii. Perform garbage collection

JRE (java Runtime Environment) the running environment of java programs constructed by JVM
