Tips for moving from C# to Java? [closed]

Question

So I'm going to a job interview next week at a Java place, and would like to not come across as clueless. I'm a pretty confident C#/.NET developer and am (clearly!) willing to consider jumping ship to Java - I'd like links to resources people would recommend for doing this. I'm interested in answers to questions like:

• Any guides that are a rough equivalent to Justin Etheridge's Ruby for C# developers? That was really useful when I decided I wanted to learn Ruby's rake (and thus at least a little Ruby). There seem to be more pages for people going the other way, though...
• Which IDE to use? I've actually already bought my own IntelliJ because I love its HTML/CSS/JS, but haven't touched its actual raison d'etre of, well, "that Java stuff". I suspect the place I'm going to uses Eclipse, however. So - recommended resources to get up and running on a Mac or Windows (I'm not fussy)?
• It's probably going to be a TDD coding interview; I guess JUnit is the de facto choice to learn a little about here?

Thanks in advance.

Answer 1

Take a look at this link which details many of the differences between the two languages.

As for IDE many people like Eclipse or Netbeans (My favorite) - Both are free. As you already own IntelliJ you could try that.

FYO some of the main differences are:

• Lack of properties / auto properties
• No 'event' type (Different way of dealing with events)
• foreach loop syntax
• 'Generics' implementation
• Checked exceptions

and probably many more :)

IDE

You got IntelliJ. Believe me its the best. I used it for two years, then had to switch to some free thingy. I tried Eclipse, it was a pain, no offense just telling you my experience. Now, working with Netbeans, and I am quite happy, but still miss IntelliJ once in a day.

TDD

Yes, you are very much right about JUnit. After enough understanding, its good to look at other specialize libraries like HtmlUnit, DBUnit. Further, a code coverage tool like Cobertura, or Emma. As you must go with IntelliJ, you will probably like to check out Emma, as its having a good integration with the IDEA.

Transition

I don't think you will have a hard time in the transition. IMO, reading the docs and the specs will get you going. May be you can go for some books down the road, but as far as core Java is concern, reading API docs and specs will be a good start. You can make use of a SO to ask question. I have seen many questions like "C# equivalent in Java ..".
