What are the Java equivalents of C# 'is' and 'as' keywords?

Question

Question says it all. Some quick code examples of usage would be nice.. thanks!

Answer 1

is => instanceof ( JLS reference ), like this:

Object foo = "hello";
if (foo instanceof String) {
  // Yup, it's a string
}

There's no equivalent of C#'s as operator in Java.

Answer 2

is (C#) -> instanceof (Java)

And you get no direct equivalent of as . You could try this one-liner though:

SomeParentType obj = 
    original instanceof Child ? (SomeParentType)original : null;
