It seems like my java code is stuck in a loop somewhere -

import java.util.random; import java.lang.math; import java.lang.string; public class gameofnim {   private int min,max;   private int turn;   private int firstturn;   private int stupid;   private int smart;   private int computer;   private int user;   private int first;   private int pile;     public gameofnim(int min, int max ){     pile=(int)(math.random()*max+min);     smart=(int)(math.random()*100);     stupid=(int)(math.random()*100);     system.out.println("pile size "+pile);     firstturn=(int)(math.random()*100 + 1);     computer=0;     user=1;     if(firstturn>50)     {         firstturn=user;     }     else     {         firstturn=computer;     }     firstturn=turn;  }   public void play()  {      if(smart>50)         {             system.out.println("computer playing smart");         }         else         {             system.out.println("computer playing stupid");         }       if(firstturn==user)              {                  system.out.println("you go first");              }               else              {                  system.out.println("computer goes first");              }           turn = firstturn;      while(pile-1>0)      {          if(turn==user)          {              string take = "how many marbles want take away?";             system.out.println(take);             int take2 = integer.parseint(take);                while(take2>(int)(pile/2))             {               system.out.println("only take away half or less pile");               take = "how many marbles want take away?";               take2= integer.parseint(take);             }             pile= pile-take2;             system.out.println("there "+pile+" marbles left");             turn=computer;                 }             else           {               if(smart>50)               {                   pile -= smarttake();               }                 else               {                   pile -= stupidtake();               }                  turn = user;             }         }        }   private int smarttake()      {         int x = (int)(math.random())*2-1;         int smarbles= (int)math.pow(2,x);         while (smarbles > (.5 * pile) || smarbles==0)         {             x = (int)(math.random())*2-1;             smarbles = (int)math.pow(2,x);         }         system.out.println("the computer took away " + smarbles +" marbles");         return smarbles;     }      private int stupidtake(){         int stmarbles = pile/2;         while (stmarbles > (.5*pile) || pile==0)         {             stmarbles = pile/2;         }         system.out.println("the computer took away " + stmarbles +" marbles");         return stmarbles;     } } 

this game of nim class

public class project5 {     public static void main(string args[])      {       string k = "yes";       string str;          scanner console = new scanner(system.in);         system.out.print("enter minimum number of marbles in pile: ");         int min = console.nextint();          system.out.print("enter maximum number of marbles in pile: ");         int max= console.nextint();         gameofnim game = new gameofnim(min, max);          game.play();        system.out.println( " thank , bye!");     } } 

and driver class

for reason everytime run it goes way point says "computer goes first" nothing else happens. im assuming stuck in loop cant seem find out why. appreciated
