Ask HN: Best way to quickly re-learn Java?
I&#x27;ve been a software dev for 9 years now. My first three years were a combo of front end and Java. since then I haven&#x27;t touched Java once (but have done PHP, python and Nodejs). I&#x27;m interested in applying to a job that has &quot;2 years focus on middle-tier&#x2F;back-end Java development&quot; as one of the main requirements. If I wanted to realistically have a shot at this position, how can I bring my self back up to speed?
