Build Java, eclipse, and codeblocks for related development environments in Ubuntu

In fact, it was prepared to set up hadoop for cloud computing courses. Simply put, we will all be ready in Ubuntu later, so we will move the development environments of CPP and python.

1. Install JDK first. The download is in the tar.gz format.

Decompress the package and configure the environment variables.

gedit /etc/profile

Of course .. You can directly

sudo apt-get install eclipse

3. Finally, install codeblocks

Apt-Get
