#ICYDK: If you’re working on multiple Java projects, it is very common to switch between different Java versions. I face this too often. We have a number of projects running in production that need a different Java version. Sometimes, we need to fix issues or to add a customer required feature in older projects. These older projects require Java version 6 or 7, while newer projects require Java 8 or 9. So, it is often required to switch between them during development.
There are many different ways to switch between Java versions, and most of them are dependent on different OS environments i.e. MacOS, Linux, Windows, etc. Below are some examples of how to do the switching. https://goo.gl/Z7bGkV
