significance of this error message

[learningjava]

Hello,

I'm trying to use reflection to create a new instance of a class.
While reading somewhere, I remember that <init> in the error has a siginificance
but I don't recall it.
java.lang.NoSuchMethodException: Control$Class1.<init>(long)

Can someone who has come across it give me an idea what could be wrong?

Thanks

<init> means a constructor.
You're trying to call a constructor which takes a long as its parameter,
but the class in question has no such constructor.

That's a constructor. The named nested class called "Class1" inside of
"Control" doesn't have a constructor that takes a single long as a
parameter, but you're trying to call it.
