While Ubuntu does have a somewhat-recent version of Eclipse in its repositories, it’s rarely the latest release. On Ubuntu 12.10, the Eclipse in the repositories in 3.8, while the latest Eclipse release at that time was 4.2, Juno.
The following script can be saved as eclipse-juno-install.sh, and will download and install Eclipse 4.2:
#!/bin/sh
# Define the URL to download the "installation" package from.
installationUrl=http://download.eclipse.org/technology/epp/downloads/release/juno/SR2/eclipse-java-juno-SR2-linux-gtk-x86_64.tar.gz
# Pull apart the name of the file that will be downloaded.
installationName=eclipse-java-juno-SR2-linux-gtk-x86_64
installationFile=$installationName.tar.gz
# Define the directory to save the install to.
installationDirectoryRoot=/usr/local/eclipse
installationDirectory=$installationDirectoryRoot/$installationName
# Create the installation directory root.
mkdir -p $installationDirectoryRoot/
# Download, extract, and relocate the installation bundle.
wget $installationUrl
tar -xzf $installationFile
rm $installationFile
mv eclipse/ $installationDirectory/
# Create the application launcher.
cat <<EOF > /usr/share/applications/$installationName.desktop

Run the following commands to mark the script as executable and then run it:
$ chmod a+x eclipse-juno-install.sh
$ sudo ./eclipse-juno-install.sh
That’s it. There should now be an Eclipse Juno application launcher available.
Troubleshooting: JavaDoc Rendering
References:
If the JavaDoc displays in Eclipse are rendering everything as plain text with the HTML stripped out, rather than rendering the HTML properly, install the libwebkitgtk-1.0-0 package as follows and then restart Eclipse:
$ sudo apt-get install libwebkitgtk-1.0-0
