Java implicit “this” parameter in method?

Question

在编程语言Java中对对象进行方法调用，通过隐式传递对象的引用来处理并作为静态方法工作？

Answer 1

Details on how method invocation works can be found in the Java SE 7 JVM specification, section 3.7 . For an instance method the this reference is passed as the first parameter. This reference is also used to select which method to invoke, since it might be overridden in a subclass, so it is a bit more complicated than a static method.

Answer 2

In short, no. That is how C++ was originally written, back when it was just a system of macros, but that was only because nothing existed (in C) like classes or static functions.

Java simply calls methods on objects. It has a shared piece of code that is the method, so in that sense it's static conceptually, but there is a bit that tells the modifiers of a method, and static is one of the bits, and it is not set for normal methods.
