Object into a String ?

Question

which of the following is the best approach for converting an Object into a String ?
String.valueOf();
.toString();
(String)

please give explanation!

Answer 1

For String.valueOf() vs .toString(), there should be not much a difference when it comes to Object.

However, if instance of class Object is null, toString() will throw NullPointerException, while String.ValueOf() will just return null.

As for casting Object to String via (String), you *can* do so as long as you know what you are doing. You are basically telling the compiler that this instance of class Object is a String, and you can safely cast it to String at runtime. If the instance of the class is actually not a String, ClassCastException will be thrown.

The best approach after taking everything into consideration (including the link) would be String.valueOf().
