Java class variables and class methods

Tag: Lin Line This instance uses ring print void log

A class variable is also called a static variable, a variable that is defined within a class that all methods can access, and a class method similar to the global variable static int = 123;java is decorated with the static keyword. For example, class Cat {static string Name;public Cat (string name, int age, string color) {This.age=age;this.color=color;this.name=n Ame;} A static method that uses static modifiers is a class method (also called a static method) that belongs to the entire class, not static void GetName () {System.out.println ("name is" +name) that belongs to an instance;} Rules in Java are class variables that use class methods to access non-static variables that cannot be accessed in a Java static method when the class method should be used: When you are writing code, there is a way to use the class method when you want all objects to be shared.
