Android: Converting a set of functions into an equation -

i 99% sure cannot done, thought ask certain.

i attempting create application calculates required dice roll action in popular tabletop war game.

the following calculation in java

        int x = ((wsattacker * 2) - wsdefender);         int y = (wsattacker - wsdefender);          string result;          // calculation +5         if (x <= -1) {              result = "5+";         }          // calculation +4         else if (x >= 0 && y <= 0) {              result = "4+";         }          // calculation +3         else if (y > 0) {              result = "3+";         } else {              result = "error";         }          return result; 

now issue avoid copywriter infringement cannot mention name of game in application, , cannot hard code above calculation in app.

this means difficult tell potential user app do.

the solution can think of make application generic , allow user input calculation required in form of equation.

an equation can place anonymously on public board or similar.

therefore questions follows.

1. is there way of going this?
2. if no, possible condense above code single expression/ equationi.e. 1 removes if , else statements

to answer question 2:

result = test_condition_1 ? result2_if_true : (test_condition_2 ? result2_if_true : test3_or_result2); 

you can build 'compound' test conditions way, , it's based upon ternary operators.

edit

ternary operators short-hand way of writing if..then..else statments, , more information can found in wiki-link above. example of use below, can compile , run:

public class ternarytest {      public static void main(string [] args){     int x = 14;     int y = 5;         string result = ( x <= 10 ) ? "less 10" : "more 10";         system.out.println("result is: " + result);     } } 

try running , see result change value of x understand how works. it's possible extend include , else replacing "more 10" string.
