I'm doing the exercises to Cay Horstmann's Java SE 8 for the Really Impatient. After doing the first two I realize that I hate the jjs RPEL command line. I've used RPELs (read evaluate print loop) in other programming languages and I don't have this reaction.
I blogged about why I dislike it and how many attempts it took me to write a simple four line program. Has anyone had a more positive experience they could share?
