+# It will also configure it as the default system JDK.
+# If you need to change to another default JDK for another purpose later, you can use the
+# following commands and select the default JDK:
+# Linux:
+#     update-alternatives --config java
+#     update-alternatives --config javac
+# MacOS:
+#     echo 'export JAVA_HOME=/Library/Java/JavaVirtualMachines/<ENTER_NEW_JDK>/Contents/Home' >>~/.bash_profile
