JList doesn't constantly refresh

[ravxm]

I'm having a problem updating my jLists. I'm trying to update it using
the jList.setListData(array) while in a loop so that it's constantly
updated. Any suggestions or strategies are greatly appreciated. Thanks

private void jButton3MouseClicked(java.awt.event.MouseEvent evt) {
int number2=4;
double arrivalrate2=.000003;
do{
if(Math.random()<arrivalrate2)
{
Random rand2=new Random();
number2=rand2.nextInt(2);
int lanenumberassigned;
Auto auto=getAuto();
LaneStatusRunnable lsrunnable=new
LaneStatusRunnable(lane1queue,lane2queue,lane3queue,lane4queue,lane5queue,lane6queue);
lanenumberassigned=lsrunnable.getLaneAssignment();
switch(lanenumberassigned)
{
case 1:
lane1queue.add(auto);
jList1.setListData(lane1queue.toArray());
System.out.println("Lane 1 assigned");
break;
case 2:
lane2queue.add(auto);
jList2.setListData(lane2queue.toArray());
System.out.println("Lane 2 assigned");
break;
case 3:
lane3queue.add(auto);
jList3.setListData(lane3queue.toArray());
System.out.println("Lane 3 assigned");
break;
case 4:
lane4queue.add(auto);
jList4.setListData(lane4queue.toArray());
System.out.println("Lane 4 assigned");
break;
case 5:
lane5queue.add(auto);
jList5.setListData(lane5queue.toArray());
System.out.println("Lane 5 assigned");
break;
case 6:
lane6queue.add(auto);
jList6.setListData(lane6queue.toArray());
System.out.println("Lane 6 assigned");
break;

default:
System.out.println("Error at lanenumberassigned
switch");
break;

}
}
}while(number2!=5);
}

The code is probably blocking the EDT.

Any suggestions or strategies are greatly appreciated.

Don't (block the EDT).

would it work as a timer fired event every few seconds??

Probably. Use javax.swing.Timer not java.util.Timer.
