First: Why can’t you import Google Map into SketchUp Model? What happend / what did you observe to come to that conclusion? The description of a problem is the way to its solution.
SketchUp does not use Java (Sun/Oracle Java, OpenJDK etc.) but something else, JavaScript. If you are in doubt, you can check again in your browser’s settings and make sure JavaScript is enabled (and you can disable Java if you like).
