In the example above we have Donna and Red both nested classes of Eric. Remember Eric is the top level class so it can’t be made static. So, that leaves us with Donna and Red. Eric is in love with Donna, meaning it would be wise of us to make Donna static. public class Eric {...
static 关键字可以应用于内部类(在另一个类中定义的类)、方法或字段(类的成员变量)。 通常,static 关键字意味着应用它的实体在声明该实体的类的任何特定实例外部可用。 static(内部)类可以被其他类实例化和引用(即使它是顶级类)。在上面的示例中,另一个类中的代码可以实例化 MyStaticClass 类,方法是用包含它的...

, fine-grain use of virtual methods, such as methods that are notstaticorfinalin the Java programming language, is extremely important to the construction of highly reusable classes, because each such method acts as ahookthat allows new subclasses to modify the behavior of the superclass....
