Quick Java Q

Hi all, anyone know how to skip to a certain line in Java?

Basically, I have:

if (something)
{
Do something else;
}
else
{
Go to line X;
}

Thanks!

can you not put what line x does in a separate method and then call that instead?

Ahh good idea! Basically, that line is System.exit(0), and apparently its bad to have more than one in a program, so I wanted to skip to it. Thanks!

The reaosn it's considered a bad idea is because you might want to change the exit behaviour in the future. For example you may want your exit procedure to involve a save before exit so if you have the exit code duplicated multiple times you have to update a lot more code and may even miss some instances of it. Having it centralised in one place allows you to make a single change.
