Install netbeans IDE 7.1.2 on ubuntu 11.10

NetBeans is a popular open-source Integrated Development Environment (IDE) used for Java, PHP, C++, and other programming languages. Although newer versions of NetBeans are available today, some developers may still need to install older versions like NetBeans IDE 7.1.2.

This guide will show you how to install NetBeans 7.1.2 on Ubuntu 11.10 step by step.

Prerequisites

Ubuntu 11.10 (Oneiric Ocelot) installed

Java Development Kit (JDK) installed (NetBeans requires Java)

NetBeans 7.1.2 installer (downloaded as .sh file from the NetBeans archives)

Step 1: Copy NetBeans Installer to Desktop

After downloading the NetBeans 7.1.2 installer (netbeans-7.1.2-ml-linux.sh), move it to your Desktop folder for easy access.

Step 2: Open Terminal and Navigate to Desktop

Open a terminal and run:

cd ~/Desktop

This command switches your working directory to the Desktop.

Step 3: Make the Installer Executable

By default, downloaded .sh files may not have execute permission. Run:

sudo chmod +x netbeans-*

This command makes the NetBeans installer executable.

Step 4: Run the Installer

Now, start the installation process by running:

sudo ./netbeans-*

You’ll be prompted to enter your administrator password. Once entered, the NetBeans graphical installer will launch.
