2. petList.addItem(1);// also tried petList.addItem(new Integer(1));

When i tried to enter string in combo box its ok , working fine , but when tried to enter numbers its bit problem ..

Error shown ...

Error:
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String

Hi -

You can always use "String.valueOf()":
Quote:
String s = String.valueOf(i);
petList.addItem(s);
Even easier, you can probably just concatenate an empty string:
Quote:
petList.addItem("" + i);
'Hope that helps .. PSM
