* All instances will share one static method, consider the consistency when the method operate a static (global) variable. [ as to its local variables, each thread has self stack. This's similar to non-static m
type the class name,scope resolution operator(double colons, ::), and the method name. To reference static members inside a class, the member must be prefixed with the self keyword followed by the scope resolution operator (::).

Static class methods are defined on the class itself. You cannot call astaticmethod on an object, only on an object class. Example classCar { constructor(name) { this.name=name; } statichello() { return"Hello!!"; } } constmyCar =newCar("Ford"); ...
package要导入的包名,ClassName类名,fieldName是静态变量名或methodName静态方法名。 2.2 全部导入 全部导入是指利用静态导入的语法,导入指定类中全部的静态变量或静态方法。语法格式如下: import static package.ClassName.*; 上面的星号是java中的一种通配符,代表所有导入的静态变量或静态方法名。
