Hi all. I have spent a fairly heavy amount of time reading through various tutorials regarding object oriented programming in Java. I was curious to see if fellow Dopers had any favorites that they went to online, or if any of you knew of good sites that had examples (dealing with inheritance and polymorphism mainly). I am working on something with the classes of suitcase, case, box, and cube and having a heck of a time getting it to work. I understand the concepts, but the language is my sticking point, so any good tutorials/examples would be appreciated.
I usually use The Java Tutorial supplied by Sun, however I have a good background with C++ and so mostly what I’m looking for are the JAVA particulars. Have you tried a quick google search?
Having taught myself Java, I found that the self-help books weren’t always so helpful. They often stress syntax, stress abstract concepts, but fail to link the two together.
However, I pretty much just muddled through it. Use taught me the errors I was having (which were, in fact, all misunderstanding how the concept applied to the syntax).
CodeGuru is a pretty decent programming message board and all around site. But without specifics it is hard to know what your problem is, or how abstract/specific your solution would be.
I’m also an experience C/C++ developer, so when I needed to learn Java I spent most of my time at the Sun web site. Great resource.
One resource that hasn’t been mentioned is Usenet. If you have a question about an issue in Java, try going to Google, selecting ‘groups’ from the Google menu, and then typing in your search term. Usenet is a very under-utilized research source, and for programming issues it’s one of the best.
