1. If this is the absolute first time you’re installing Java, just run the update-alternatives command to update the preferred Java as default update-alternatives —config java and select the option number for Java 7
2. if you have already installed Java once check whether a symlink exists in /etc/alternatives sudo ls -al /etc/alternatives/java
   If you see a listing similar to the following lrwxrwxrwx 1 root root 46 Jun 20 21:51 /etc/alternatives/java -> /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
   The symlink exists and only needs to be updated using the command — update-alternatives —config java
   This will list the available Java executable files available in your system, like so —
   (including the JDK 7 executable you’ve placed in /usr/lib/jvm) Note the asterisk(*) next to option 1. This indicates the default version of Java being used.
   If the JDK 7 location is listed here, enter the option number and hit enter to set JDK 7 as the default.
3. If for some reason no listing is provided after running the update-alternatives command, check if the symbolic links(symlink) are setup properly sudo ls -al /etc/alternatives/java
   if no file is found, create the symlink — sudo ln -s /etc/alternatives/java /usr/lib/jvm/jdk1.7.0_80/bin/java
   Also, create a symlink in /usr/bin to ensure availability of the Java executable in the terminal. So first check if the file exists in /usr/local— sudo ls -al /usr/bin/java if no file is found, create the symlink — sudo ln -s /usr/bin/java /etc/alternatives/java

(Fix is no longer working as noted by @Christian Rodriguez)

After downloading the the Oracle JDK 7 package from Oracle’s website, place the file in the location —

(create the oracle-jdk7-installer folder if it is not already present)

Then open a terminal(shortcut: Ctrl+Alt+t ) and execute each of the following commands(one after the other) —

 sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer 

To verify the installation was successful, execute the following command —

You should see a message similar to the one shown below —

The Software Bundle Distribution

The Java TM SE Development Kit 7 Update 80 and NetBeans TM IDE 8.0.2 Java SE Software Bundle is distributed for various platforms as follows:

Note: Java TM SE Development Kit 7 Update 80 cobundles JavaFX 2.2.

Installing the Software Bundle on Microsoft Windows

To install the software, you must have administrator privileges on your system. The installer places the Java Runtime Environment (JRE) software in %Program Files%\Java\jre7 , regardless of the specified JDK install location.

Note: This installer does not displace the system version of the Java platform that is supplied by the Windows operating system.

1. Verify that your system meets or exceeds the minimum hardware requirements:
   1. 800MHz Intel Pentium III or equivalent
   2. 512 MB of RAM.
   3. 750 MB of free space Note: The installer uses the %USERPROFILE%\Local Settings\Temp directory to store temporary files.
   1. For the 32-bit Windows operating system, the installer file name is jdk-7u80-nb-8_0_2-windows-i586.exe .
   2. For the 64-bit Windows operating system, the installer file name is jdk-7u80-nb-8_0_2-windows-x64.exe .

   Installing the Software

   1. Double-click the installer file to run the installer.
   2. At the Welcome page of the installation wizard, click Next.

      2. Accept the default JDK installation to use with the IDE or specify another JDK location.

      Installing the Software Bundle on Linux

      You can install the JDK software and NetBeans IDE in directories of your choice. You do not have to be a root user to use this installer unless you choose to install this bundle in a system-wide location.

      Note: This installer does not displace the system version of the Java platform that is supplied by the operating system.

      Before you install
