there are many ways to get the full qualified name of a java Class in kotlin:

get name via the property KClass.qualifiedName:

val name = AClass::class.qualifiedName; 

OR get name via the property Class.name:

val name = AClass::class.java.name; 

OR get name via the method Class#getName:

val name = AClass::class.java.getName(); 

the table of the qualified name of a class as below:

|-----------------------|-----------------------|-----------------------| |                       |          Class        |     Anonymous Class   | |-----------------------|-----------------------|-----------------------| | KClass.qualifiedName  |    foo.bar.AClass     |         null          | |-----------------------|-----------------------|-----------------------| | Class.name            |    foo.bar.AClass     |    foo.bar.AClass$1   | |-----------------------|-----------------------|-----------------------| | Class.getName()       |    foo.bar.AClass     |    foo.bar.AClass$1   | |-----------------------|-----------------------|-----------------------|
