Examples of java.util.prefs.Preferences.keys()

java.util.prefs.Preferences.keys()
Returns all of the keys that have an associated value in this preference node. (The returned array will be of size zero if this node has no preferences.)
If the implementation supports stored defaults and there are any such defaults at this node that have not been overridden, by explicit preferences, the defaults are returned in the array in addition to any explicit preferences. @return an array of the keys that have an associated value in thispreference node. @throws BackingStoreException if this operation cannot be completeddue to a failure in the backing store, or inability to communicate with it. @throws IllegalStateException if this node (or an ancestor) has beenremoved with the {@link #removeNode()} method.
