Java如何将“逻辑和运算符”分配给“布尔变量”

Question

It is just my curiosity whether I can do something like

private static boolean and = &&;

I wonder whether a "logical and operator" can be assigned to a "boolean variable".

PS I can't compile the sentence, because it already gave an error. Since variable initialization requires tokens and && is not a token.

Answer 1

You can't do this in Java. If you have your heart set on doing something like this, try using the preprocessor command #define in C or C++.

Beware though - this is NOT recommended as you'll have a lot of trouble debugging and finding other developers to work on code with you.

You may even end up with your own entry on TheDailyWTF (like this , this , this , this , or this )

Answer 2

Here is an example using English grammar, the way I see it:

"And" and "True" are different parts of speech. "True" is an adjective, so you can say, "That is true." "And" is a conjunction, so it does not make sense to say "That is and."

Same thing with && and true . && is an operator "part of speech," whereas true is a value "part of speech." Because of this, it doesn't make sense to set a boolean value to an operator . Perhaps something like this could be done, if instead of boolean and = && you could type BooleanOperator and = && ; however, there is no such type or functionality in Java (see Chris's answer about C).

For years people have wanted sentence like programming. If you can make a language that does that, then awesome! However java cannot be converted to sentence like programming. Perhaps you could write a string modifying class that assigns certain words to other characters that it would then input into whatever text editor you are using. Good luck debugging though!
