I need help with a program that prints random lines from a file

[jonjon1456]

I need to write a program that gets inputted files from arguments written from command prompt and prints a random line from it. I don't really know how many exceptions i need and I don't really understand the logic of getting the line from the file. Please help me.

A scanner object is created the same way any other Object is created in Java. If you don't know anything about Objects and how they are created, go read the Java tutorial stickied for this forum.

I don't really know how many exceptions i need

if you want to have a minimum, just put everything in one HUUUGE try-catch block, catching a standard Exception.

otherwise, just write the code you think you'll need, try to compile it and you should get messages like:

unhandled ...Exception at line ...

that should give you an idea of what Exception to handle with, and, more important, about where to do so
