I am using windows 7 64, IDE netbeans 8. I have got some projects compiled in different jdk versions jdk 6, jdk 7 and jdk 8, manytimes I face the error of major.minor, to avoid it I am changing the jdk according to need, but it consumes a lot of time to install and uninstall jdks again and again. Is there any easy way to add and use all the jdks in the netbeans by switching etc.?
If you have a project open, you can go to file -> project properties. At the bottom of the window you'll find a menu labeled source/binary format. You should be able to select the jdk version there.
