Converting from CharSequence to String in Java [duplicate]

Question

Suppose I want to convert a CharSequence to a String in Java.

Which option (1 or 2) is better and why?

CharSequence source = "some text";
String someText1 = (String)source; // 1
String someText2 = source.toString(); // 2

Answer 1

The best option is behind Door #3:

String someText = String.valueOf(source);

Because that will handle the case where source is null.

Answer 2

#1 doesn't even work for CharSequence implementations other than String, so #2 is really your only option.
