Article Introduction：1. What is the Java Virtual Machine? When you talk about the Java Virtual Machine, you may be referring to: 1. The abstract Java Virtual Machine specification 2. A specific Java Virtual Machine implementation 3. A running Java Virtual Machine instance 2. Java The life cycle of a virtual machine A running Java virtual machine has a clear task: execute Java programs. It runs when the program starts executing and stops when the program ends. If you run three programs on the same machine, there will be three running Java virtual machines. The Java virtual machine always starts with a main() method, which must be public, return void, and directly accept a string array. You must specify this to the Java virtual machine when the program is executed
