values of variables changing despite not modifying them

Hi,

My problem is in the following code. The code with *** is changing the values of sensors.get(i).getTemperature and/or sensors.get(j).getTemperature. If I leave this line out, the temperatures appear normal. With that line, they take unexpected large negative values. Anyone know what's going on and have a possible solution? Thanks

Code :

---

 public static boolean verifyAssessor( Assessor assessor, List<Sensor> sensors)
    {
    boolean result = true;
 
    int i,j;
    int consistentWith = 0;
    int functioningSensors = 0;
 
 
    for(i=0;i<sensors.size();i++){
      consistentWith = 0;
      for(j=0;j<sensors.size();j++){
        if(i!=j){
          if(Math.abs(sensors.get(i).getTemperature()-sensors.get(j).getTemperature())/sensors.get(i).getTemperature() <=
              Assessor.ERROR && sensors.get(i).getTemperature()!=-1 && sensors.get(j).getTemperature()!=-1){
             consistentWith ++; //***
          }
        }
      }
      //Count the number of functioning sensors
      if(consistentWith>=2){
        functioningSensors ++;
      }
    }

Can you put your format your Code Correctly?
