+# Install and run Java Examples
+
+## Prerequisites:
+Please follow the Step 1 in the [Scala configuration](http://mxnet.incubator.apache.org/install/scala_setup.html#setup-instructions)
+These should help you install the correct Java version and all dependecies.
+
+## Import and run the Java package
+For users using a desktop/laptop, we recommend to use IntelliJ IDE as it is tested and supported to provide necessary documentation for the Java API.
+
+Alternatively, users can follow the second instruction to setup a empty Maven project for Java.
+
+### IntelliJ instruction
+If you are using a computer with Ubuntu16.04 or Mac, you can install IntelliJ to run the Java package. Please follow the instruction below:
+
+1. Create a new Java project in IntelliJ. Fire up IntelliJ and click `Create New Project`. It should open a popup window like this :
+
+2. Click `Next`, and in the `Create project from template` window, do not select anything and click `Next` again.
+
+3. In the next window choose your `Project name` and the `Project location` and click on `Finish`.
+
+4. Let’s add the Java Inference API jars that we grabbed from Mavel Central. At the top of the window, Go to the `File -> Project Structure`. In the popup window that opens up, click on `Libraries -> +` and select the path to the jar files downloaded. Click `Apply` and then click `OK`.
+
+6. Create a new Java class under the folder `your-project-name/src`. Let’s call this class `JavaSample.java`. Type in the following code snippet and run it. In this code snippet we create an NDArray object in Java and print it’s shape.
