Helping folks is why where here. There are plenty of books and online resources that explain syntax and such, so i'd pick up one of those. Lots of folks around here (myself included) like "Head First Java" by Bert Bates and Kathy Sierra. Bert even moderates a few forums around here. Others like "Thinking in Java" by Bruce Eckel, which you used to be able to download for free (not sure if that is still true or not).
Start with something like that, then come back here and ask more questions. come back here and read what others are posting, and try and learn from the thousands of discussions already here.
There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
Have a look at the Java Beginners FAQ - it contains useful information and links for getting started with Java. And ofcourse, if you have specific questions, ask them here on the forum! Have a good time learning Java.
