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();
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.
