JRE vs OpenJDK vs Oracle JDK

Before we go on seeing the process to install Java, let’s quickly understand the difference between JRE, OpenJDK and Oracle JDK.

- JRE (Java Runtime Environment) is what you would need normally to run a Java based application. This is all you need if you are not a programmer.
- JDK stands for Java Development Kit and this is what you need to if you have to do some development (read programming) related to Java.
- OpenJDK is Open Source implementation of Java Development Kit while Oracle JDK is the official Oracle version of Java Development Kit. While OpenJDK is sufficient for most of the cases, some programs such Android Studio suggests to use Oracle JDK to avoid UI/performance issue.
