finding location java_home in Windows 10

I need help finding the location of my java_home/bin, or if it even exists. If it doesn't, what more do I need to install?

I am following some installation directions, and one of the steps says:

Ensure that the Java Runtime Environment (JRE) is installed on the computer and that the java_home/bin directory is defined in the system path.

I can't even find the path of java_home. Disregarding the directions for other OS, this is the closest I've come to finding something helpful.

However, when I type the prescribed command, echo %java_home% it just returns %java_home% as a string, percent signs and all. When I try % java -version down further in the page, it tells me %java isn't a recognized command, program, or batch file.

I have Java 8 Update 60 installed, I can see it in my list of programs I can uninstall. From the quote though, I have in mind that if I have a JRE installed, then java_home\bin exists. However, I've had File Explorer search very nearly the entire computer, and found nothing.

Solution 1:

I need help finding the location of my java_home/bin

• "Start" > "Control Panel" > "Java".

• Select "Java" tab.

  

• Click "View"

• Look in the "Path" column for version of the JRE you have installed.

  

In the above example the "Path" contains:

C:\apps\jdk\jre\bin\javaw.exe

JAVA_HOME should point to the root directory of the Java installation, so in this case:

C:\apps\jdk

And the PATH should contain JAVA_HOME\bin, in this case:

C:\apps\jdk\bin

From a command prompt we can set these values using the following commands:

setx JAVA_HOME C:\apps\jdk
setx PATH C:\apps\jdk\bin;%PATH%

Notes:

• Modify the above commands as appropriate for your Java installation.
• These are System not User environment variables.
