I have a `JList` that uses a list model to add strings of text to the `JList`. I am having trouble figuring out how to update a selected `listModel`. I am able to select the `listModel` String (I have verified that what ever I select returns correctly) but I am unable to figure out how to update the `listModel` string I select. Any help with this would be greatly appreciated. Is there a `updateElement(variable)` or something I could use to accomplish this?

```
    String string1 = "hello";
    String string2 = "goodbye";
        String myItem = jlst.getSelectedValue();
    // myItem is the string returned
        listModel.addElement(string1 + string2);
// adds a new element is there anyway to update myItem so string1 and string 2 become apart of the myItem string ?

```
