Answer 1

Since the JList method 'getSelectedValues' returns an object array you'll need to iterate through the array and cast each object in the array to a string as you access them.
Object[] o = colorList.getSelectedValues();
for(int count=0,end=o.length; count<end; count++) {
String s = (String) o[count];
Hope that helps
