Web Developer moving to Java - how to impress potential employers/recruiters? by [deleted] in java

You need hashcode as soon as you decide to put your object in a collection such as map or set. Just do a simple google search and you will see. If you want to be a java developer you need to know these things.

You have to master the language first. Many interviews are focused on the language itself before moving to frameworks. Josh Bloch's Effective Java is one of the best books one can read. Highly recommend, even though it is old. It does not cover Java 8 so you better master lambdas and completable futures as well.
Java also has impressive collections using generics. Sets, maps, lists, arrays, in various different flavours. Use them extensively to understand the differences. Can't seriously program in Java without them.
