1. Overview

In this short tutorial, we're going to take a look at a few ways to determine if Java is installed on a machine.

2. Command Line

First, let's open a command window or terminal and enter:

If Java is installed and the PATH is configured correctly, our output will be similar to:

Otherwise, we'll see an error message like the one below and we need to check elsewhere:

The exact messages we see will vary depending on the operating system used and the Java version installed.

3. When Path Is Not Set

Going to a command line and typing java -version can tell us for sure if Java is installed. However, if we see an error message, Java might still be installed – we'll just need to investigate further.

Many discussions about using java -version mention the JAVA_HOME environment variable. This is misleading because JAVA_HOME won't affect our java -version results.

Additionally, JAVA_HOME should point to a JDK and other applications that use JDK features, such as Maven, use it.

For more information, please check our articles JAVA_HOME should point to a JDK and how to set JAVA_HOME.

So, let's look at alternative ways to find Java, in case the command-line failed us.

3.1. Windows 10

On Windows, we can find it in the Application list:

Press the Start Button
Scroll down the application list to J
Open the Java folder
Click About Java

We can also look at installed Programs and Features:

In the Search bar, type Control Panel
Click Programs
If the Java icon present, then Java is installed
If not, click Programs and Features, and look for installed versions of Java in the J's

3.2. Mac OS X

To see if Java 7 or greater is installed on a Mac we can:

Go to System Preferences
Look for the Java icon

For earlier versions of Java, we'll need to:

Open Finder
Go to the Applications folder
Go to the Utilities folder
Look for the Java Preferences app

3.3. *Nix

There are few different package managers in the *nix world.

In a Debian-based distribution, we can use the aptitude search command:

If there is an i before the result, then that means the package is installed:

4. Other Command Line Tools

In addition to java -version, there are some other command line tools we can use to learn about our Java installation.

4.1. Windows where Command

In Windows, we can use the where command to find where our java.exe is located:

And our output will look something like:

However, as with java -version, this command is only useful if our PATH environment variable points to the bin directory.

4.2. Mac OS X and nix which* and whereis

In a *nix system or on a Mac in the Terminal app, we can use the which command:

The output tells us where the Java command is:
