I have been doing Scala and Groovy at the day job for about a year now. For some side work I thought I'http://neidetcher.blogspot.comd use Java, there obviously aren'http://neidetcher.blogspot.comt enough semi-colons in my life. I haven'http://neidetcher.blogspot.comt touched 1.7 yet and setting it up on my Mac wasn'http://neidetcher.blogspot.comt incredibly intuitive.
I had to do more poking around to arrive at this than I wish I had to.
Finding the actual download from Oracle is easy.
After installing Java 1.7 from Oracle I added this to my ~/.bashrc to actually use it. Not sure if the install should'http://neidetcher.blogspot.comve done this or if I missed some steps I was supposed to take.
And holy cow Oracle does not make it easy to find out how to download the JDK 1.7 API documentation. Got to have it local for coding on an airplane.
