After the refactoring, all USES of that number or string literal in the class refer to that field, instead of the number or string literal itself.

在重构后，所有对这个类中的数字或字符串文字的使用都将指向该字段，而不是指向数字或字符串文字本身。

Comparing a variable having an atomic value (number, Boolean, or string) to another such variable or a literal atomic value, and expecting the type of one to be cast automatically to the other type.

把包含原子值(数字、布尔值或字符串)的变量和另一个此类变量或者文字原子值比较，希望一种类型自动转换成另一种类型。

This way, you can modify the number or string literal in just one place (the value of the field), instead of doing a search and replace throughout your code.

这样，在一个位置(字段的值)就可以实现对所有数字或字符串文字的修改，再也无需在整篇代码中执行查询和替代了。

So, for the most part any time we talk about or draw pointers an arrow suffices, which really 71 in there is a number like 71, which is the literal byte that the F is actually in in RAM, but frankly who cares?

所以，每次我们讨论,或者用箭头表示指针,在指针里面有一个数字，如,那是F在RAM中的字节，但是谁在乎它呢？
