It is usually good practice to initialize variables with a default value, this is so if for any reason your variable doesn't get given a value in your code it already has a value of some kind to show or work with.

As the variable type is String we can initialize them using empty double quotes as shown below.

String title = "";
String author = "";

Hope this helps

I get it now, so it is not wise to just leave String title and then end it off with ;. But by putting String title = ""; then it can be set for default without messing up or crashing. Thanks!
