Re: java update problem(beginner:/)
You can have multiple JDKs installed on your system at once. So you don't need to uninstall the previous one before installing a new one. You can switch the active version by changing the JAVA_HOME environment variable. Point it to the version that you want to use. If you are working with an IDE you can also register multiple JDKs on your IDE. And then pick one for the current project you are working on.
