I had heard of it but not looked into it deeply. I did read that Java 7 uses dual pivot quicksort for primitives and timsort for objects. I wasn't sure if dual pivot was not good for objects (which could have possibly-complex comparators) or if timsort was just simply good for Java's use cases. It seems accessible to try doing, so I'll look into that. -- John Naylor EDB: http://www.enterprisedb.com
