Installing the Java SDK (JDK) also installed the Java runtime environment (JRE).

Since Linux on ARM is not a platform officially supported by Oracle (Solaris, Windows, Linux on x86 and x64) this installs OpenJDK, an open-source implementation.

private:/$ java -version
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8.2) (6b18-1.8)
OpenJDK Zero VM (build 14.0-b16, mixed mode)

Apparently I ended up with Java 1.6. Wikipedia informs me that the current version is 1.7, so I am not too outdated here.

Testing the Java environment with a Hello World program gives this positive result:

private:~$ javac HelloWorld.java
private:~$ ls HelloWorld.class
HelloWorld.class
private:~$ java HelloWorld
Hello, world.

That appears to work.

So I am done here.
