#18426 — How to eliminate warning: unchecked call to additem(E) java as a member of the raw type javax.swing.JComboBox

Without removing warnings in general, for the below code, how can I remove the below warning.

jComboBox6.addItem("Big rock");

Warning: unchecked call to additem(E) java as a member of the raw type javax.swing.JComboBox

Thank you,

to handle this warning in netbeans right click jcombobox and go to properties and open it,then click code tab and find Type parameters and write String in it. this will fix your problem and want generate this warning. doing this will do same as this code >  JComboBox<String> jComboBox6 = new JComboBox<String>(...); and fix it.

     // NO:
     JComboBox jComboBox6 = new JComboBox(...);

     // YES:
     JComboBox<String> jComboBox6 = new JComboBox<String>(...);

Forget Netbeans and learn Java.

     In the NetBeans form editor, select the JComboBox.  In the
Properties panel, click the Code tab.  Open the Type Parameters
editor, enter <String> in the box, and close.

> Thank you,

     It seems to me that you are having more trouble with the
NetBeans form designer and its artifacts than with Java and
Swing.  The designer is an intricate beast, with little controls
and menus and twiddly bits festooned all over the landscape, to
the extent that I imagine it might take most of a year's solid
effort to master the complexity.  Someone with that mastery
could probably churn out forms faster than someone just typing
Java code -- but the typist has several months' head start while
the other guy is learning how to use the designer.

     If you expect to be doing a LOT of form designing, by all
means spend the time to learn the form designer inside and out.
But if you just want a simple form or three, skip the designer:
It will just get in your way (as it seems to be doing now).  If
you're having trouble achieving some particular effect you might
create a mock-up in the designer and study the generated code to
get ideas, but I truly think you'll get to a better outcome sooner
by writing the Java code yourself.

see sample code at http://mindprod.com/jgloss/jcombobox.html

The trick is JComboBox<String>
