regarding Throwable

[Raj Kumar Bindal]

when i write throw new Throwable(),it is working.I wonder how we can write new in front of an interface because Throwable has no constructor,so how it is possible.Any comments.

[Peter Chase]

Throwable isn't an interface, it's a class.

You are correct in your idea that you cannot instantiate an interface directly. But this is not relevant to Throwable, as it's a class.

Note that you should never instantiate Throwable directly, in any real application. It is legal Java to do so, but very bad practice. You should only instantiate Exception, RuntimeException or Error, or (better) their subclasses.

I also thought Throwable is an Interface.
