im not sure whats wrong code, seems things coming prime.

public static char isprime(int x)         {             char result = 'r';             for(int y=2;y<x;y++)             {                 if(x%y==0)                 result = 't';                 else                 result = 'f';             }             return result;         } 

you going end of loop result x-1.

you need start result = 't' , break out of loop false values.
