Java Annotated Monthly – August 2019
It’s August and frankly there are better ways to be spending one’s time than worrying about work. If you do feel the urge to use your downtime to level up your technical knowledge, or if you’re working through the expensive holiday season, then as usual this month’s Java Annotated Monthly should have what you need. But if you skip a month in order to focus on something else that’s more important, like family, friends, or taking some time to recharge and look after yourself, that might bring you more value.
