Netbeans 8.1 on Ubuntu 17.04

Question

I tried installing Netbeans by clicking on the apt link here : https://doc.ubuntu-fr.org/netbeans

the installed package is "netbeans"

ergo : sudo apt install netbeans

the program runs the splash screen for a couple of seconds then crashes.

Any tips?

The tutorial that you followed to install NetBeans 8.1 is obsolete. Current versions of NetBeans require openjdk-8-jdk, not openjdk-6-jdk or openjdk-7-jdk as recommended in the tutorial. Uninstall openjdk-6-jdk and openjdk-7-jdk if you don't need them, and install openjdk-8-jdk using the following command:

sudo apt install openjdk-8-jdk

Hopefully installing openjdk-6-jdk/openjdk-7-jdk didn't permanently mess up your Java path and you can get started using NetBeans immediately.

The version of NetBeans from the default Ubuntu repositories is 10.0 in Ubuntu 18.04 and later.

Try some other IDE that are native to Linux World such as Geany instead of NetBeans.

see this link to install open-jdk. How to compile a .java file on Ubuntu?

after that simply you can use Gedit to code and javac command in terminal as java compiler.
