How to emulate C# as-operator in Java

Asked 2008-09-29T14:11:56.647

There are situations, where it is practical to have a type-cast return a null value instead of throwing a ClassCastException. C# has the as operator to do this. Is there something equivalent available in Java so you don't have to explicitly check for the ClassCastException?

You can use the instanceof keyword in place of C#'s is, but there is nothing like as.

Example:

if(myThing instanceof Foo) {
   Foo myFoo = (Foo)myThing; //Never throws ClassCastException
   ...
}
