I can't find any .deb packages for Sun's Java Development Kit. How can I install it on my Debian machine without causing conflicts with the already installed openjdk packages? 
How can I install Sun JDK on a Debian based system?
debian;java;jdk
You can create a Debian package from the Oracle tarball using the make-jpkg command from the java-package package. Here is an example:make-jpkg jdk-7u45-linux-x64.tar.gzYou can then install the resulting .deb file with dpkg -i:sudo dpkg -i oracle-java7-jdk_7u45_amd64.deb Finally, make this the default Java environment using update-java-alternatives:sudo update-java-alternatives -s jdk-7-oracle-x64Source: https://wiki.debian.org/Java/Sun
