Question

I have a JList that is filled with an Array. I just want to print the value when the user selects something in the list and presses a button. I know it’s something to do with getSelectedValues. When I searched online I got solutions to JLists filled with addItems but not when filled with an Array.

This is the code for the button at the moment:

    public void actionPerformed(ActionEvent evt) {
                Object[] selected = FilmList.getSelectedValues();
                String[] selectedItems = new String[selected.length];               
                System.out.println(selectedItems);

            }

The name of my JList is FilmList and the name of my array is films.
Thanks guys.

EDIT
you should use
Object[] selected = FilmList.getSelectedValues(); System.out.println(java.util.Arrays.toString(selected));

OR If you want to store it in array of String you can do like this:

String[] selectedItems = new String[selected.length]; 
for (int i = 0 ; i < selectedItems.length ; i++)
{
 selectedItems[i] = (String)selected[i];
}

And then you can print the same as:

System.out.println(Arrays.toString(selectedItems));

You can also print the values using for loop as:

for (int i =0; i < selectedItems.length ; i++)
System.out.println(selectedItems[i]));
