What is the difference between CharSequence[] and a String[]?

Question

What is the difference between CharSequence[] and String[]?

Answer 1

CharSequence is an interface. String is a class that implements the CharSequence interface. That means a String object passes as a CharSequence object. There are different classes that implement the CharSequence interface. They all define the methods that correlate with the method signatures (or abstract methods?) that the interface CharSequence provides.
