```
Next to Make Processing IDE Desktop Launcher
For a System-Wide Setup:
```
sudo sh /opt/processing/install.sh
```
Instead, only for your User:
```
sh /opt/processing/install.sh
```
5. Setting Up Java

(Optional) Check if Oracle Java JRE is Installed
```
java -version
```
As beginning you can just starting to make Use of the Bundled Java release.

Fixing Java for Processing
Remove the Bundle Java release:
```
sudo rm -rf /opt/processing/java
```
Symlinking the Oracle JRE Installation:
```
sudo ln -s /usr/java/[jre1.X] /opt/processing/java
```
To finds the [jre1.X] Value to be replaced:
```
ls /usr/java
```
