Ever wondered which Java version is used to run your NetBeans instance? I have a lot of JDK's installed and everytime I install a new one it ones to be the default JDK for my computer. To know which JDK is used for running NetBeans we go to Help | About and the dialog box shows which Java version is used:
To explicitly tell NetBeans which JDK to use we can use the command-line argument --jdkhome when we start NetBeans. Or we can set the property netbeans_jdkhome in the file netbeans-install-dir/etc/netbeans.conf.
