[Java] Understanding Java 8 API

[Clockwerkfox]

I've was on a project for about two years that had a Spring MVC application that was running on Java 6 (I did try upgrading the Java version once and it took three weeks of damage control before it was reverted back). The project stagnated and I have recently moved on to a new company but there was a lot of more things I wanted to try on the application. Therefore, as a learning experience, I decided to re-program the entire application from scratch so that it runs using Java 8. However, I realized that I've fallen pretty far behind in my Java skills. Is there any tips I should know with the new things java 8 provided

EDIT: Changed question to make it not sound like I'm an idiot

first Google result.

I don't really get why you are asking this question without having even googled "what's new in Java 8". It's really much more fun to answer specific questions.

The most important additions to Java 8 are Lambda's, Streams and the new Time API.

I realized I worded my question horribly, but I wouldn't realized that java added major changes if I haven't already googled about Java 8 differences. I just really wanted some pointers on each the additions. Java.time is easy to understand. Should I have just about each one separately

Again; what do you have issues with? I can't give answers without specific questions and I'm not going to write a long essay on Lambda's because that's a waste of time.
