Java APIs

Please help me out with this, I'm new to Java and I can not figure this one out. I also tried it by including throw Exception after the args statement and it was able to create the file but nothing printed in it.

Thanks

Error:
unreported exception java.io.FileNotFOundException; must be caught or declared to be thrown
