On almost every Java interview on intersting project with the top technologies you will be asked about Stream APIs. So, you are required to know Stream API and all its tricky methods. Here I am providing useful links to do this effectively :
-> http://javadevblog.com/polnoe-rukovodstvo-po-java-8-stream.html – the article just to be familiar on high level with Stream API opportunities. You can try some interesting methods in your IDE if you would like to.
-> https://habrahabr.ru/company/luxoft/blog/270383/ – useful trot to recall Stream API before technical interview
-> http://www.coreservlets.com/java-8-tutorial/ I recommend this site to do all the exercises in Secrions ‘Streams 1’ – ‘Streams 3’. Upload exercises results to you GitHub account
-> https://ok.ru/video/65646330375081-1 – very useful video in the Russian language . Required to watch !!!
Have a nice day, guys ! Please write in the comments what tricky interview questions on Streams you were asked on your technical interviews 🙂
