Java Forum / General / August 2007Possible to group different ints to do one command?
I'm writing a code, and to save space I'm wondering how I could do this. There's no easy way to do this so I'll just give an example: int blueCoins = playerBlueCoins; int redCoins = playerRedCoins; int greenCoins = playerGreenCoins; //...and so on... Is there some way for me to say "If the value of any of these ints is greater than 99, the value is 99" without having to write it for every single int? > I'm writing a code, and to save space I'm wondering how I could do > this.

Build it up pairwise with Math.min(). If you're looking for a comparison amongst all the ints, you are perforce going to examine every int. There is not a way to circumvent physics.

Ultimately there is no way to find the min() of a set of comparable values without examining every value. You could build it up pairwise with Math.min() or use java.util.Collections.min() over a Collection of the values (including Integer.valueOf(99) ).

There's no easy way to do this so I'll just give an example: Don't worry so much about space as complexity and understandability. > int blueCoins = playerBlueCoins; > int redCoins = playerRedCoins; [quoted text clipped - 4 lines] > greater than 99, the value is 99" without having to write it for every > single int? Well, you could write a class to represent a number of coins in this context. Otherwise you are left with: int blueCoins = Math.min(playerBlueCoins , 99); ...

Any time you find yourself saying something like "for every single int" reconsider whether you should have an array or map that could be processed in a for-loop, rather than several separate variables.
