### Question:
NameRegistrar implements Loggeable { public static <T> T getIfExists(String key) { @SuppressWarnings("unchecked") T obj = (T) sp.rdp(key); return obj; } private  NameRegistrar(); static TSpace<String, Object> getSpace(); static Map<String,Object> getAsMap(); static NameRegistrar getInstance(); static void register(String key, Object value); static void unregister(String key); static T get(String key); static T get(String key, long timeout); static T getIfExists(String key); void dump(PrintStream p, String indent); void dump(PrintStream p, String indent, boolean detail);  }### Answer:
@Test public void testGetIfExists() throws Throwable { String value = NameRegistrar.getIfExists("test2"); assertThat(value, is("testValue2")); }
@Test public void testGetIfExistsWithNotFoundKey() throws Exception { String value = NameRegistrar.getIfExists("NonexistentKey"); assertThat(value, is(nullValue())); }
