the title says clearly. wanted use quicksort algorithm 1 of friends said use comparator don't know how to. you must create comparator: comparator<string> comparator = new comparator<string>() { public int compare(string s1, string s2) { return s1.compareto(s2); } }; with comparator able sort data in alphabetical order. after create sorter , pass comparator , model of jtable. then: sorter.sort(); i think after data sorted.

i have question regarding backgroundworker . can call progresschanged event without having started thread runworkerasync . i don't understand why works. how can notify original thread if new thread didn't start yet? this seems work regardless, since updates gui without problem, wasn't before implemented backgroundworker . calling reportprogresschanged() raise progresschanged event regardless of thread called from. inside inplementation of reportprogresschanged() mechanism raises event on ui thread if wasn't called ui thread. if reportprogresschanged() is being called ui thread, raises event without needing marshalling.

doing following risking exception 'there no bar on undefined' var obj = o.foo.bar the way can think of doing above safely : var obj = (o && o.foo && o.foo.bar ) ? o.foo.bar : null; or putting entire thing in try/catch not option in cases me.. , results in more code if want different thing happen depending on property missing. is there concise way perform assignment safely? ** update ** tweaked @techfoobar's answer function resolve(obj, propertypath) { if (!propertypath) return; var props = propertypath.split('.'); var o = obj; for(var in props) { o = o[props[i]]; if(!o) return false; } return o; } var res = resolve(obj, 'apiresponse.commandresponse'); if (res){ (var in res){ seems it's going get... one way moving function can re-use in multiple scenarios regardless of depth need go: function resolve(_root) { if(arguments.length == 1) return _root; // in case...

for example, consider following expressions: no_space = "this test".match(/(\w+)(\w+)/) with_space = "this test".match(/(\w+) (\w+)/) the expression no_space matchdata object #<matchdata "this" 1:"thi" 2:"s"> , while with_space #<matchdata "this is" 1:"this" 2:"is"> . going on here? seems me literal space between tokens indicates ruby should match multiple words if possible, while not having space causes match limited 1 word. explanation or clarification on subject appreciated. thanks. \w doesn't match space, , + greedy unless follow ? , ruby tries match many \w possible, long rest of express matches, consuming thi in first capture, , s in second. when add space, ruby matches many \w until space character, , many \w , therefore matching this , is . please let me know if isn't clear.
