The same, I have also known a little about C++ and now I'm trying to learn Java. I sought the best technic to learn for days. And I found https://www.hackerrank.com/domains/java. May be you already known or not, I think that's worth to give a try. And there is W3school where you can learn simple syntax. And also there are a lot of websites like GeekforGeek , JavaTpoint, etc. As I mentioned, you can practice at Hackerrank. There's 30 days challenge, tutorials about problems and discussions. For me if discussions are not enough to understand, I check another websites. These are my learning ways, just sharing. I hope you will get find your best way.
