What is a virtual machine?
A virtual machine is an abstract computer that simulates various computer functions on a real computer.
What is the JVM?
The FULL name of JVM is Java Virtual Machine, also known as Java Virtual Machine.
Java virtual machines have their own complete hardware architecture, such as processors, stacks, registers, etc., as well as corresponding instruction systems.
A very important feature of the Java language is platform independence. The use of Java virtual machine is the key to achieve this feature.
The JVM shields platform-specific information, allowing Java programs to run unmodified on multiple platforms by generating object code (bytecode) that runs on the Java VIRTUAL machine.
Recently, a lot of friends asked me for some information about the JVM, so I dug through my suitcase and found this very classic ebook, The Actual Java Virtual Machine :JVM Troubleshooting and Performance Optimization.
Information on
Real Java Virtual Machine: JVM Fault Diagnosis and Performance Optimization introduces Java VIRTUAL machine parameters configuration, troubleshooting, performance monitoring, and performance optimization through more than 200 examples. Not only for Java programmers, but also for any developer, software designer, architect working on Java virtual machines.
