I am new to Java Programming and I have a populated JLIST.  But when the users add a new element I want the JLIST to be sorted.  I am not finding a easy way to do it.
String[] emails = project.getEmailAddresses(); <--- getting email address from a function	    	
    	listModel = new DefaultListModel();
    	
    	
    	for (int i = 0; i < emails.length; ++i) {
         	listModel.addElement( emails[i]);      <-- adding them to the JList 	
        
        }    	    	

Open in new window


but I need to figure out how to sort the list when the user adds a new email - which is done when I Button

listModel.insertElementAt(addEmail.getText(), index);

Any help would be great

I have seen that article, but it seems to be a bit more than I need.  But if you think that is the only way to do the sort I will start trying to put it in my code

I agree that the article has provided a great deal of information, mostly (I think) to make it as general as possible.

You could probably simplify things a bit depending upon your specific needs and environment.
However, if anyone else is ever going to look at the code, it might be best to be as complete as possible.

This also allows you to use the same concept (i.e., SortedListModel class) elsewhere.

My preference is to keep a collection of utility classes available, and reuse them whenever possible.

in your case you could just sort the array before creating your model
