Compiler error is coming, if I'm trying to pass String arg

CodePudding user response：

That's not the correct way of doing it, you can't pass through parameters when assigning types.

take the following as example:

val foo : String  

here, i'm specifying that my variable foo is of type String, right ? That's exactly what this statement is doing as well :

catch (e: Exception)

you're saying that e is of type Exception, you can't create a new instance here.

that means that you should change your code to be something like this:

catch (e: BaseException) {}

and then where you need to use this, you'd do something like:

throw BaseException("Test"))
