Scala Question

What is the Scala equivalent of Java's ClassName.class?

How do I get an instance of

in Scala? In Java, I can do this:

Class<String> stringClass = String.class;

What would be the equivalent in Scala?

Answer Source

There is a method classOf in scala.Predef that retrieves the runtime representation of a class type.

val stringClass = classOf[String]

You can use the getClass method to get the class object of an instance at runtime in the same manner as Java

scala> val s = "hello world"
s: String = hello world

scala> s.getClass
res0: Class[_ <: String] = class java.lang.String
