Hi, > is this worth it ?
No. There are better ways to improve performance :-) > this performance issue is already solved in a modern JVM Not completely. This particular case is much better optimized in JDK 1.6. But usually, the JVM has to do a bit more when calling interface methods. There is still a difference, for example if you make 'list' a private field: Java 1.6 List: 2278; ArrayList: 1710 Regards, Thomas
