Release 6 is not found in the system - Creating a Project

Question

I have now a little experience in Java, so I wanted to take the next step to an IDE, so I installed the Eclipse IDE. (If it matters, I am using mac.)

But this does not seem to work right, as soon as I create a new class, the error occurs:

The project was not built due to "release 6 is not found in the system". Fix the problem, then try refreshing this project and building it since it may be inconsistent HelloWorld

I already tried to change some of the properties in the class or selecting different settings, right now I use the execution environment JRE: J2SE-1.5.

Thank you for taking your time!

Well it is basically telling you that you don't have the right version of Java JDK installed. THIS page seems to imply the current version of eclipse needs 1.8 - not the 1.6 you're talking about. I am unsure though how you could have specified one that isn't installed. Maybe you only have the JRE (java runtime environment). You will definitely need the JDK (java development kit) because that is what has the java compiler in it.

It's been a long time since I used eclipse but when you created the project you should have been prompted to specify the java version. Now try right clicking on the project and choose Build Path... Configure Build Path. On the Java Compiler tab (left side) you should be able to change the configured Java to whatever you have installed.
