block, I'm going to show a program without the main method, javac it without any errors. public class Test {static { System.out.println ("Static"); Nbsp;system.exit (0);}} Variables in Java are broadly divided into two broad categories: member variables and local variables. member variables: Variables defined within the class body are called member variables; If the member variable has a

A Brief Introduction to several memory regions of the jvm virtual machine: Method Area: There is a memory area dedicated to storing loaded class information, constants, static variables, and method code in the java Virtual Machine, Constant pool: a constant pool is a part of the method area. It is mainly used to store information such as symbolic references in constants and classes. Heap: used to store clas

Differences between 1.java and C # static member invocationStatic, which is a shared resource, is created when the class is loaded.Java can be invoked through an instance, or by a class name. member name, but it is generally preferable to use the class name.

Summary: static code blocks are always executed first. A non-static block of code, like a non-static method, is related to an object. Only non-static blocks of code are executed before
