Procedure 7.4. Replacing a Key Value

1. The following code searches for keys (named key and key2). If the two specific keys beings searched for are not found, JBoss Data Grid creates two new keys with the specified key names and values.

   cache.putIfAbsent("key", "newValue");
   cache.putIfAbsent("key2", "value2");

   assertEquals(cache.get("key"), "value");
   assertEquals(cache.get("key2"), "value2");
