(1) jdk Installation

You need to use Pycharm in Ubuntu, but Pycharm is written in Java, so jdk must be installed. There are a lot of installation methods. I found a suitable Ubuntu on the official website and provided the following documents:

========================================================== ====

Installation of the 64-bit JDK on Linux Platforms

This procedure INSTALLThe Java Development Kit (JDK) for 64-bit Linux, using an archive binary file (.tar.gz ).

These instructions use the following file:

jdk-8uversion-linux-x64.tar.gz

1. Download the file.

   Before the file can be downloaded, you must accept the license agreement. the archive binary can be installed by anyone (not only root users), in any location that you can write. however, only the root user can install the JDK into the system location.

2. Change directory to the location where you wowould like the JDK to be installed, then move the .tar.gz archive binary to the current directory.

3. Unpack the tarball and install the JDK.

   % tar zxvf jdk-8uversion-linux-x64.tar.gz

   The Java Development Kit files are installed in a directory called jdk1.8.0 _ version in the current directory.

4. Delete the .tar.gz file if you want to save disk space.

========================================================== ====

Obviously, sometimes you may find that reading official English documents is better than searching for tutorials on the Internet. Although there are many online tutorials, sometimes they are also messy. At this time, it is better to look for official documents. Link can see here: http://docs.oracle.com/javase/8/docs/technotes/guides/install/linux_jdk.html

After the installation is complete, decompress jdk in the/usr/lib/java directory.

(2) Configure Environment Variables

Run the following command:

1	echo "PATH=$PATH:/usr/lib/java/jdk1.8.0_65/bin" >> ~/.bashrc

Make the configuration take effect:

1	source ~./bashrc

Enter java:

123456

xpleaf@leaf:~$ java Usage: java [-options] class [args...]           (Execution class)   Or java [-options]-jar jarfile [args...]           (Execute the jar file)......................

Relatively simple.

(3) Better installation and configuration methods

Of course, you must do it yourself. If you think it is too troublesome, you should use the online method. Another benefit of doing so is that you do not need to manually configure it.

1. Update the software source first.

Sudo apt-get update

If there is always a problem when updating the software source, you can consider changing the software source, just put/etc/source. you can modify the content in the list. For which update source is better, check your network environment. I can search for some items on Baidu. It is recommended that I use domestic products.

2. Install jdk

Sudo apt-get install openjdk-8-jre

If you are prompted that you do not have the software, it indicates that it is a problem with the software source. Change the software source.

3. Enter java

If you enter java, a prompt is displayed, indicating that the configuration has been completed for us.
