Where is Java Installed on Mac OS X?

Question

I downloaded Java 7u17 on Mac OS 10.7.5 from here and successfully installed it. To do some JNI programming, I need to know where Java is installed on my Mac.

I thought that inside the /Library/Java/JavaVirtualMachines/ folder, there would be a folder called 1.7.0.jdk or something, but then I found the folder empty. This was confirmed by running ls /Library/Java/JavaVirtualMachines/ in the Terminal. I've tried searching for it to find out if it was installed somewhere, but that doesn't seem to be turning anything up.

Could someone please tell me where Java is installed on my Mac?

To close voters/reopeners - this question is explicitly not off-topic (questions about tools commonly used by programmers). Unfortunately, it got bandwagoned by meta. — Rob, Commented May 10, 2016 at 0:35
I found the JDK in /Library/Java/JavaVirtualMachines/. I'm using macOS Big Sur(11.0.1). And installed jdk version is 1.8.0 — Chaitanya, Commented Feb 14, 2021 at 19:51

Use /usr/libexec/java_home -v 1.8 command on a terminal shell to figure out where is your Java 1.8 home directory

If you just want to find out the home directory of your most recent version of Java, omit the version. e.g. /usr/libexec/java_home

I got to this question because I was getting an error in eclipse on my mac because I was getting an error on the first line of the program "import java.util.*." I strongly suspect this is because the java path isn't set correctly or something (even though I set this up once before). I entered the command in this answer and I get a directory. Can I just paste that directory into the textbox in the "Native library folder config" window? Or does this directory belong somewhere else?

Added export JAVA_HOME=`/usr/libexec/java_home` to .bash_profile so JAVA_HOME is always set (note the back-ticks around the libexec command)

If you just want to know if the JDK is installed on your mac, omit the version number and run from terminal: $ echo $(/usr/libexec/java_home)

On Mac 10.12.3, we should /usr/libexec/java_home -- v to show the most recent version of java

Note that macOS Big Sur changed the behaviour of the java_home command. Noe, if if the JAVA_HOME environment variable is already set to a valid JDK that is all it will return, it will ignore the -v parameter. If JAVA_HOME is set to an invalid folder, the java_home command won't work at all. To get a reasonable output you must unset JAVA_HOME before invoking /usr/libexec/java_home

command in your terminal to know the path where Java being installed.

Turns out that I actually had the Java 7 JRE installed, not the JDK. The correct download link is here. After installing it, jdk1.7.0jdk appears in the JavaVirtualMachines directory.

Try This, It's easy way to find java installed path in Mac OS X,

GoTO

1 ) /Library i.e Macintosh HD/Library

2) Click on Library in that we find Java folder.

3) So final path is

/Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home

Hope so this is help for someone .

You do not need sudo to run find for generally-accessible commands. If you don't want to see the error messages about inaccessible directories, get rid of the messages rather than using root privs unnecessarily. Using sudo all the time is a bad habit. Redirect stderr to /dev/null, like this: find / -name java 2> /dev/null

If you type

java -verbose

This also gives the location from which the jars are loaded and hence also the java path.

Java package structure of Mac OS is a bit different from Windows. Don't be upset for this as a developer just needs to set PATH and JAVA_HOME.

So in .bash_profile set JAVA_HOME and PATH as below. This example is for Java 6:

export JAVA_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
export PATH=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin:$PATH

You may not realize it, but you likely have multiple Java versions installed.

To list the version, architecture, and folder location of all installed JVMs on your Mac:

$ /usr/libexec/java_home --verbose

Or:

$ /usr/libexec/java_home -V (That's an uppercase V!)

Sample output:

$ /usr/libexec/java_home -V
Matching Java Virtual Machines (4):
    12.0.1 (x86_64) "Oracle Corporation" - "Java SE 12.0.1" /Library/Java/JavaVirtualMachines/jdk-12.0.1.jdk/Contents/Home
    1.8.202.08 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_282 (x86_64) "Amazon" - "Amazon Corretto 8" /Users/username/Library/Java/JavaVirtualMachines/corretto-1.8.0_282/Contents/Home
    1.8.0_202 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
/Library/Java/JavaVirtualMachines/jdk-12.0.1.jdk/Contents/Home

This is a more complete answer IMHO. I had multiple versions installed and the /Internet Plug-Ins/... was causing an issue with the Java updater tool, but I couldn't find the version the tool was complaining about ... until now. — wildcat12, Commented Sep 21, 2022 at 22:19

I have just installed the JDK for version 21 of Java SE 7 and found that it is installed in a different directory from Apple's Java 6. It is in /Library/Java... rather then in /System/Library/Java.... Running /usr/libexec/java_home -v 1.7 versus -v 1.6 will confirm this.

I tried serkan's solution, it found java 7's location on OS X Mavericks. it is resided in "/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/" but to make it the default JDK I had to set JAVA_HOME system variable in .bash_profile in home directory to "/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/" so its up and running now thanks to serkan's idea
