title: Do I need both JDK and JRE?
body: <p>I used to have JRE 7 before, and now I installed JDK 8 and deleted my JRE 7 folder. I'm using Eclipse Kepler, and I added JDK 1.8 to my installed JRE's. Can I delete the JRE 1.8 folder as it's taking up space in my computer? Will it cause any problems?</p>
