No, because in Java, the "order" of the properties is not recorded anywhere. Each Java compiler can put the methods into the .class file in any order they want. Also, at runtime, the returned array from things like getMethods and getFields can be in any order the runtime wants. There are no guarantees. For example, the IBM JDK is notorious for returning them in the exact REVERSE order than the Sun JDK. The new Java7 jdk seems to use a more "random" order. This is one of the most common issue when porting JUnit tests from one JDK to another. If you have multiple @Test annotated methods in a class that DON'T properly cleanup and thus leave side effects that other tests may rely on, those tests tend to randomly fail on Java7.
