I have defined an object(Tracker) with four variables and in a class have declared an array of this object:
Tracker track[] = new Tracker[max];
However in a for loop when I try to set the values of the variables The code hangs for no apparent reason.
for (int i = 0; i < track.length; i++){
track[i].agname = agNames[i];
track[i].priority = priority[i];
}
Would anyone have any ideas???

Hi Hilary,
could you please send the entire code(How does your Tracker class look like?)
Ajay
below is the code for the Tracker. It is instantiated in an agent. I didn't supply all this code but the beginning. You
couldn't run it without the agent platform.
package IE.BROADCOM.ISYS.ASL.Hilary;
//ASL imports
import IE.BROADCOM.ISYS.ASL.agentName;
public class Tracker{
agentName agname = null;
String reply = null;
int priority = 0;
int times[] = {6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,00}; //max number of hours to be dealt with
public Tracker(){
agname = null;
reply = null;
priority = 0;
}
public int findTime(Tracker[] tracker, int numAgents){
int proposeTime = 9; //earliest one would want a meeting at?
for (int i = 0; i < numAgents; i++){
for (int j = 9; j < 18; j++){
if (tracker[i].times[j] == tracker[i+1].times[j])
proposeTime = tracker[i].times[j];
}
}
return proposeTime;
}
}

Maybe you could add one line to initialize the tracker object before you use it.
for (int i = 0; i < track.length; i++)
{
track[i] = new Tracker();
track[i].agname = agNames[i];
track[i].priority = priority[i];
}
