Later this year, the sun.com domain is supposed to go dark. The world turns, and Java is now managed by Oracle, which bought Sun. So, to run a Java application someone else provides, you need JRE to develop a Java application, you need JDK.Īs Chris Marasti-Georg pointed out in a comment, you can find out lots of information at Sun's Java web site, and in particular from the Java SE section, (2nd option, Java SE Development Kit (JDK) 6 Update 10).
