I am a windows user, and wonder how do I go about installing java on Ubuntu (VirtualBox)

I have tried 

sudo apt-get install sun-java6-bin

got

couldnt find package

sudo apt-get install sun-java6-jre

got

sun-java6-jre has no installation candidate

I also tried the .bin file:

sudo chmod 755 <filename>.bin
./<filename>.bin

Seems like it has done its things without errors, but

java -version

gives

the program 'java' can be found in the following package ...

Sun Java has been moved to the Partner repository in Ubuntu 10.04 (Lucid Lynx).

Add the repository by doing this:

add-apt-repository "deb http://archive.canonical.com/ lucid partner"

Then you can do:

sudo apt-get update
sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts

The steps to install Java 8 on Ubuntu:

  1. At first, download the package file from the official website.

    http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html. The download package is different for 64 bit and 32-bit versions.

  2. You will need some superuser privileges to install JDK. So use the following command-

    sudo su

  3. The /opt directory is actually reserved for all the software and add-on packages. This software is not part of the default installation. The command for creating directory for JDK installation is

    mkdir /opt/jdk

  4. Then extract java into the /opt/jdk directory:

    tar -zxf jdk-8u5-linux-x64.tar.gz -C /opt/jdk

  5. Then use the following command. This command verifies the file extraction into the /opt/jdk directory.

    ls /opt/jdk

  6. By default, you can find java executable in /opt/jdk/jdk1.8.0_05/bin/java directory. To set it as the default JVM use:

    update-alternatives --install /usr/bin/java java /opt/jdk/jdk1.8.0_05/bin/java 100
update-alternatives --install /usr/bin/javac javac /opt/jdk/jdk1.8.0_05/bin/javac 100

  7. Then verify the java has been successfully configured. Run the following commands:

    update-alternatives --display java
update-alternatives --display javac

    You can check installation by

    java -version

  8. You can also update Java. Hence, download an updated version of Oracle’s website and extract to the /opt/jdk directory. After that, set it as the default JVM with a higher priority number:

    update-alternatives --install /usr/bin/java java /opt/jdk/jdk.new.version/bin/java 110
update-alternatives --install /usr/bin/javac javac /opt/jdk/jdk.new.version/bin/javac 110
