Questions tagged [system-properties]

System properties a key value pairs that can be provided to an application, often used to configure it at run time.

In Java there is a set of predefined properties that specify things like operation system, java version and the current user. A complete list can be found at http://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html

One can also provide arbitrary system properties when executing a java application using the -D commandline parameter like the following example:

java -Dkey=value ClassToExecute

Inside the program the properties can be accessed using System.getProperties() or similar methods in the same class.
