In Java, is String s = new String() any use at all?

Question

Since Strings are immutable in Java, why would I want to use the argument-less String constructor and create an object?

How is the variable s useful to me after I do:

String s = new String();

Answer 1

new String() is an empty string. This could be a return value from a method, for example, if you don't have anything more interesting to return. Using the literal "" is probably better because the literal empty string value will already be interned.
