In means that you are trying to remove an item that does not exist

[shady05]

But I have a lot of items in JList .

i want to acces the particular item by getting its index i.e
int index =jList1.getSelectedindex();
then remove element by
jList1.remove(index);

y the hell it aint working

[JamesCherrill]

Try printing the value of selectedIndex one line before the exception - that may reveal something interesting

[mKorbel]

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {

   int selectedIndex = jList1.getSelectedIndex(); // if isn't there any row selected, then jList1.getSelectedIndex() returns -1
   if (selectedIndex != -1) { // or selectedIndex > -1 
      jList1.remove(selectedIndex);
   }
}

@mKorbel
Yes, definitely a good idea - necessary really.

But it doesn't explain his Exception
"java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 1"
1 (not -1) points to his JList being empty ( < 2 entries).
Maybe he has shadowed the jList1 variable with a new one somewhere?
