loops - Java Monopoly Game -

i made board , set board's layout null. position token's moving them pixel pixel. when turning corners having trouble. after first 10 position token can make turn , continue next 10 position. impossible token make 2. turn.
can advice me better code problem. think make things more complicated is.

            if(g.getposx() <= 650 && g.getposx() >= 50 && g.getposy()==650) {             if(g.getposx()-unitchange*d.getdice() <= 50) {                 temp = unitchange*d.getdice() - (g.getposx() - 50);                 g.setposx(50);                 g.setposy(g.getposy()-temp);             }             else {                 g.setposx(g.getposx()-unitchange*d.getdice());                   temp = 0;             }         }         else if(g.getposy() <= 650 && g.getposy() >= 50 && g.getposx()==650) {             if(g.getposy()-unitchange*d.getdice() <= 50) {                 temp = unitchange*d.getdice() - (g.getposy() - 50);                 g.setposy(50);                 g.setposx(g.getposx()-temp);             }             else {                 g.setposy(g.getposy()-unitchange*d.getdice());                   temp = 0;             }         }         else if(g.getposx() <= 650 && g.getposx() >= 50 && g.getposy()==50) {             if(g.getposx()-unitchange*d.getdice() <= 50) {                 temp = unitchange*d.getdice() - (g.getposx() - 50);                 g.setposx(50);                 g.setposy(g.getposy()-temp);             }             else {                 g.setposx(g.getposx()-unitchange*d.getdice());                       temp = 0;             }         }         else if(g.getposy() <= 650 && g.getposy() >= 50 && g.getposx()==50) {             if(g.getposy()-unitchange*d.getdice() <= 50) {                 temp = unitchange*d.getdice() - (g.getposy() - 50);                 g.setposy(50);                 g.setposx(g.getposx()-temp);             }             else {                 g.setposy(g.getposy()-unitchange*d.getdice());                   temp = 0;                }         } 

instead of using current x , y positions track location piece stopped on, try tracking property piece has landed on instead. property 1 first stop on board after go way boardwalk @ position 39. can have function

moveplayertolocation(player player, int location){      // calculate x , y based on property locatoin      if(locatoin < 11){       // on first edge     } else if (location < 21) {       // on second edge     } else if (location < 31)        // on third edge     } else {       // on fourth edge of board     }    // g.setpos-ing }
