IJava is a Java library typically used in Editor, Code Editor, Jupyter applications. IJava has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has medium support. You can download it from GitHub, Maven.

A Jupyter kernel for executing Java code. The kernel executes code via the new JShell tool. Some of the additional commands should be supported as needed via a syntax similar to the ipython magics. The kernel is fully functional. Check out the list of features further down in the README. Any requests for new ones or prioritizing current requests are welcomed in the issues along with bug requests, installation help, or other questions. If you are interested in building your own kernel that runs on the JVM check out the related project that this kernel is build on, jupyter-jvm-basekernel.

I am trying to use java in jupyter notebook using SpencerPark IJava.

After the successful installations I opened a new java notebook but it is not connecting with the jupyter notebook.

I tried running this command given on the official docs of SpencerPark IJava in anaconda prompt

IJava is compiled for java 9 (as this is the version that introduces JShell). This means the kernel needs to run on a JVM that is version 9 or higher. That is what the Unsupported major.minor version 53.0 is suggesting.

Typically users that run into this problem have installed a correct version but they have an older JVM that is being used instead of their newly installed one. There are 2 options to fix this:

Tell Jupyter exactly what version of java to start the kernel with by changing the kernel.json:
- Execute jupyter kernelspec list to find the install directory of the kernel.

How to change runtime type in google colab when the change runtime type option does not show?

Asked 2020-Oct-26 at 14:01

I would like to run java in colab.

I successfully installed ijava and reloaded the page, but the "change runtime type" option does not show.

In this case, how do I switch from Python to Java kernel? Is there a command line trick by which I could manage to do it?

This is my colab link: https://colab.research.google.com/drive/1XyVBfMJ3m23IsDVjPER7G-UZ0vd4gT2c?usp=sharing

Thank you.

The only way to change to ijava is to download the notebook. Open it with a text editor and edit it manually.

So normally, you would use a pre-edited notebook. At the start, it cannot find ijava so it will use python3. After you install ijava, and reload, it will then use ijava.

Here's a shortcut to a pre-edited ijava notebook
