1. Ensure JDK updated to the latest version

2. Download IJava

? ? ?ijava下載地址：https://github.com/SpencerPark/IJava/releases

Unzip it into a temporary location. It should have at least the?install.py?and?java?folder extracted in there.

在install.py和java上層文件夾中打開(kāi)terminal:

# Pass the -h option to see the help page

> python3 install.py -h

# Otherwise a common install command is

> python3 install.py --sys-prefix (其實(shí)直接運(yùn)行這步）

3. Check if java-kernel loaded

>jupyter kernelspec list

如果kernel列表中有java，則ok了。

下面在jupyter notebook里面新建代碼文件時(shí)，可以選用使用java kernel。
