the following code print 2 string word = "bannanas"; string guess = "n"; int index; system.out.println( index = word.indexof(guess) ); i know how indexes of "n" ("guess") in string "bannanas" the expected result be: [2,3,5] this should print list of positions without -1 @ end peter lawrey's solution has had. int index = word.indexof(guess); while (index >= 0) { system.out.println(index); index = word.indexof(guess, index + 1); } it can done for loop: for (int index = word.indexof(guess); index >= 0; index = word.indexof(guess, index + 1)) { system.out.println(index); } [note: if guess can longer single character, possible, analyzing guess string, loop through word faster above loops do. benchmark such approach boyer-moore algorithm . however, conditions favor using such approach not seem present.]

yesterday spent time trying find bug. long story short, realized because of constructor: public triangle(list<vertex> vertices) { this._values = vertices; } i tried initialize object list of values , object took reference object instead of getting values list. if don't abandon list passed parameter , use later else initializing else same values or if decide clear , fill new values, destroy state of triangle object without knowing it. my first reaction "fix bug" in constructor started thinking if it's way should be. what's practice covers things that? in general, should think constructors/init methods take list of values? should leave intact? allowed reuse list , fault when leads error? i mean, can that: var triangle = new triangle(new list<vertex>(vertices)); but shouldn't done creators of triangle class already? i know guidelines on that. thanks. personally agree henk; should create copy. /// <summary> ...

i use mousemove listener on google maps, while want handle click event too. var path = new google.maps.mvcarray; ... line = new google.maps.polyline({ map: map, path: new google.maps.mvcarray([path]), }); google.maps.event.addlistener(map, 'click', function(event) { path.push(event.latlng); }); google.maps.event.addlistener(map, 'mousemove', function(event) { if (path.getlength() > 1) path.setat(path.getlength()-1,event.latlng); }); i want follow mouse line, if user click on map, push polyline's array. click event doesn't work... idea? i think there small bug in code: on line 5 should read path: path, instead of path: new google.maps.mvcarray([path]), reason: var path mcvarray , property path of polylineoptions expects mvcarray, supply mvcarray inside normal array inside mvcarray. this prevents code following pushing coordinates correct array.

given: public struct id { readonly int m_id; public id(int id) { m_id = id; } public static implicit operator int(id id) { return id.m_id; } public static implicit operator id(int id) { return new id(id); } } can implicitly convert ienumerable<int> to ienumerable<id> and vice versa. in way. note var ids = new int[]{ 1, 2 }; ids.cast<id>(); does not appear work , covariance not appear working in case, either. of course, doing select work i.e.: ids.select(id => new id(id)); but looking make work implicitly, writing: ienumerable<id> ids = new int[]{ 1, 2 }; and yes, know can written as: ienumerable<id> ids = new id[]{ 1, 2 }; but issue in cases enumerable of ints comes different source, such file example. i sorry if there answer this, not find it. according this answer want not possible. can close not implicitly casting id collection. : public class ids : list<int> { pub...
