Throw in constructor

Hello

In a construtor of a class in an example, I found that

public MyClassName {

if (...)

throw new AnException //not runtime exeption

}

I wonder why in this constructor, I cannot find throws clause such as

public MyClassName throws AnException {

..

Please help -why, and if there is exception, what happen?

Regards

su
