List toArray   necessarily returns an array of Object  To get an array of String  you need to use the casting syntax   String   strarray   strlist toArray new String 0      See the javadoc for java util List for more

You want  String   strarray   strlist toArray new String 0      See here for the documentation and note that you can also call this method in such a way that it populates the passed array  rather than just using it to work out what type to return   Also note that maybe when you print your array you d prefer  System out println Arrays toString strarray      since that will print the actual elements
