Scratch

To the knowledge of a windows user who wanted to know if he could develop java if he ever got enough money for a Mac, Java (both JRE and JDK) are included in OSX. Try typing 'javac' into terminal to see if it is installed.

Edit: yeah. There isn't even a download for Mac OSX except the JDK 7 beta.

But JDK is preinstalled for macs

Macs come with the JDK.  Type 'javac file_name.java' into the Terminal application after you have navigated to the correct directory ('cd folder' to go into a folder, 'cd ..' to exit a folder; it starts on your user folder).  Then type 'java class_and_file_name' to run it.  There's also another, longer command to turn the .class file that you'll create with javac into a .jar.

Find a good tutorial !FOR MAC! Most books use an IDE but you can't. Or just sell your 2000$ mac and get a windows. </completely unbiased>

I would say get netbeans or eclipse, but those don't work on mac. Then I would say get NPP, but that's, also, just fow windows. Just use TextEdit or whatever sorcery you have on macs and use javac or java from the command line.

netbeans works on mac
eclipse i think it does

So kids the lesson is - Do your research FIRST

Okay, this means that you do have the JDK already installed. You'll need to learn Java now (I recommend TheNewBoston on YouTube) and then you're all set!

The problem is I don't even know how to access JDK from there......

Are you expecting a program such as Scratch? The JDK is the BARE basics needed to create Java programs. It includes the JRE, the compiler (Javac on command line) and a few other tools. If you want to do all the hard work yourself, just fire up a text editor and save your program as a .java file. Navigate to the directory of the file and type "javac yourprogram.java". Note that Java is a case sensitive language, meaning that if your program is named "HelloWorld.java" and you type "javac helloworld.java" there will be an error.
If you want the computer to do most of the work for you, as well as be more organized, you will want an IDE, or Integrated Development Environment. This organizes your program in packages, catches bad syntax (like spell check in Word or Pages) and features options for exporting your program easily. Most commonly used are Eclipse and Netbeans, which I believe have already been linked to above. If not, Google it.
