Java中关键字final用于声明原始数据类型(primitive types)和对象引用为不可变对象,但是它不能使对象本身变为不可变对象。 原始数据类型(primitive types)变量(int, long, short等)定义之后还可以再重新赋值,可以使用final阻止这样的赋值。 int i = 42; //int is of primitive type i = 43; // OK final int ...

Python passes references-to-objects by value (like Java), and everything in Python is an object. This sounds simple, but then you will notice that some data types seem to exhibit pass-by-value characteristics, while others seem to act like pass-by-reference... what's the deal?
