本文探讨了Java中实例方法调用的晚绑定机制，解释了为何Java不会在编译时绑定方法调用，而是在运行时进行选择。此外，文章还讨论了通过不同方式引用同一对象来体现多态性的概念。

Java uses "late-binding" for calling instance methods.

Late-binding means Java doesn't "bind" (think: choose) a method call to an actual method at compile time. The choice of method happens later... at run-time.

Compile time = early, run-time = late. I get it.

Referring to an object in many different ways (reference type is different from actual object class) is the point of polymorphism, which means "many forms".
