But you can get some other benefits from that later - like the ability to do checked casts with memberClass.cast()[00:57:51] <dmlloyd> CaBa: what do you mean by "the order of an array". You mean you just want a copy?[00:58:01] <CaBa> dmlloyd: no. the indizes[00:58:10] <gionny> dmlloyd: now I understand it better, thanks[00:58:12] *** vinse has quit IRC[00:58:19] <dmlloyd> CaBa: the indices of an array are always 0..array.length[00:58:25] <dmlloyd> array.length - 1 that is[00:58:27] <CaBa> dmlloyd: oh, really?[00:58:32] *** gengid has quit IRC[00:58:36] * cybereal chortles[00:58:44] <CaBa> dmlloyd: i want an int[] with the right order of the indizes[00:58:55] *** G0-T0 has joined ##java[00:59:02] <cybereal> bwahahah[00:59:03] <CaBa> dmlloyd: smt like "int[] ascendingOrder(Object[] objects, Comparator c)"[00:59:03] <dmlloyd> CaBa: the indices are always in the right order[00:59:13] <CaBa> dmlloyd: u are so smart[00:59:23] <cybereal> CaBa: I don't think you understand what you're asking[00:59:35] <dmlloyd> CaBa: ooooh.
