Class variable is accessed as: className.classVariableName. Static variable is pretty like constant, declared with key word "static", stored in static memory, created when program begins and destroyed when program ends. 2. Java Static Method: A static method belongs to a class rather than a o...

可以的。类可以有内部类,具体问题。具体再追问。错误提示是说:非静态变量类型不能在静态上下文中引用。(1)你的;main方法是static的,即静态的。(2)如果你将类包含在里面的话,需要将printchar声明为静态的。才能在main方法中引用。首先
