SunJava - Debian Wiki

Sun Java is now a package in non-free. Either install the Java development kit:

#apt-get install sun-java6-jdk

or the Java runtime environment

#apt-get install sun-java6-jre

For Etch you will find Java 5 instead:

#apt-get install sun-java5-jdk

or the Java runtime environment

#apt-get install sun-java5-jre

Sun recommends you update the alternatives system to have Sun's tools as the default:

#update-java-alternatives -s java-6-sun

Or for java 5:

#update-java-alternatives -s java-1.5.0-sun
