Well of course you can use System.setProperty("myprop", "myval");

Or ...

You can set properties when you start your application using the -D 
command line switch.

something like

javac Foo.java
java -Dmyprop=myval Foo

in you code you can access these properties like so
System.getProperty("myprop");

This would return the String "myval"
