Ironically, the 'Java' control panel under System Preferences shows only Java 1.8! usr/libexec/java_home -V still only lists the old Java 1.6. I've tried adding a symbolic link to make it look like 1.8 is in the /System/Library. But /usr/libexec/java_home doesn't find 1.8, so all the posts I've found on how to set your current java version don't work. Not sure why the latest installer puts this in /Library instead of /System/Library (nor what the difference is). I ran Oracle's Java 8 installer, and the files look like they ended up at /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdkīut previous versions are at /System/Library/Java/JavaFrameworks/jdk1.6. I'm using IntelliJ 13 CE and Mac OS X 9 Mavericks.

Under 'Java Platform, Standard Edition' ⇒ 'Java SE 11.0.

Then, proceed to 'Step 3: Write a Hello-world Java program'.

If message 'To open javac, you need a Java runtime' appears, select 'Install' and follow the instructions to install JDK.

If message 'command not found' appears, JDK is NOT installed.

If the JDK version is prior to 1.8, proceed to Step 2 to install the latest JDK otherwise, proceed to 'Step 3: Write a Hello-world Java
