I wonder how to get a class object for an object type in Scala. Ok, that is a mouth full because of the double meaning for object. So here an example which will fail:
object Main { private [this] val TAG = classOf [Main].getName; } // Main If Main was class it works perfectly. Any ideas?

A classOf[T] is a value of type Class[T] . In other words, classOf[T]: Class[T] . For example: scala> val strClass = classOf[String] strClass: Class[String] = class java. lang. String scala> :t strClass Class[String]
Scala is more object-oriented than Java because in Scala, we cannot have static members. Instead, Scala has singleton objects. A singleton is a class that can have only one instance, i.e., Object. You create singleton using the keyword object instead of class keyword.
Use the getClass Method in Scala The getClass method in Scala is used to get the class of the Scala object. We can use this method to get the type of a variable.
If you have a JavaSW object, you can obtain it's class object by calling getClass() on the object. To determine a String representation of the name of the class, you can call getName() on the class.
