It has been in Eclipse for ages. It’s admittedly only a bit hard to find. First start with
switch (myEnum) {
}
At that point, your cursor would usually be inside the statement block {}. You need to put your cusror back to the line with the switch keyword and press Ctrl+1 and choose Add missing case statements. This way it will insert any possible case.
You’d intuitively expect this option to be available inside the statement block {} as well, but no.
Update: since Eclipse Kepler (or perhaps already Juno, but it’s so instable that I never really used it), this option is finally available via Ctrl+1 inside the statement block as well.
