I want to learn Java, but it’s kinda complicated. Where can I find good tutorials?

Have you tried the “dummies” series…they have several editions… Java for dummies, Java 2 for dummies.etc.etc. Hope this helps.

How about of Daniel Shiffman. The learning curve it´s incredible smooth and dinamic and at the end of the book you not only know Processing, you also learn basic java and good roots of clever object oriented programing .
After that switching to openFrameworks it´s really easy
