where need to use collections.sort() and comparable and comparator interfaces in java collection? -

i got understanding of collections gone through articles. 'm confusing should implement collections.sort() method , need use comparable interface(compareto() , comparator interface (compare()). comparable interface compare , reference object comparator compare 2 objects. i know situation need use methods ? thanks, you should not implement collections.sort() ; method built-in java . call method without supplying comparator sort natural order , if it's comparable . else, supply comparator sort comparator 's way. you should have class implement comparable , provide compareto method if class has natural ordering , indicated in comparable javadocs. example integer , double , have natural mathematical ordering. you should create class implements comparator when cannot make class of object sort comparable or when want present ordering alternative natural ordering, or when want impose order when there no natural ordering. example reverse natural

file - C++ return string keeps getting junk -

why return string here have sorts of junk on it? string getchunk(ifstream &in){ char buffer[5]; for(int x = 0; x < 5; x++){ buffer[x] = in.get(); cout << x << " " << buffer[x] << endl; } cout << buffer << endl; return buffer; } ifstream openfile; openfile.open ("bacon.txt"); chunk = getchunk(openfile); cout << chunk; i load of junk in string has junk on end of it, though debug says buffer being filled correct characters. thanks, c++ lot harder java. you need null terminate buffer. make buffer size 6 characters , 0 initialize it. fill first 5 locations you're doing now, leave last 1 alone. char buffer[6] = {0}; // <-- 0 initializes array for(int x = 0; x < 5; x++){ buffer[x] = in.get(); cout << x << " " << buffer[x] << endl; } cout << buffer << endl; return buffer; alternately, leave array size same, use string constructor

scheme - Number in Sequence that a pair falls in -

i want find number in sequence pair falls in. trying write procedure verifies f(1, n) = 2n - 2 , f(m+1, n+1) = 2f(m, n). works when call (number 99, 100), doesn't work when call (number 100, 100). why doesn't work? sequence number (100, 100)? here procedure: (define (number m n) (if (= m 1) (- (* 2 n) 2) (* 2 (number (- m 1) (- n 1))))) why believe procedure "doesn't work"? function, defined, correctly implementing desired formula - , lead base case when both m , n equal: (- (* 2 1) 2) ; if m equals 1 n equals 1 the above return 0 of course, , multiplications in recursion cancel, because you'll multiplying 0 on , on again: (* 2 (* 2 ... (* 2 0))) => 0 so problem not in procedure itself, in formula it's implementing. make sure it's correct.

i have xml like: <root> <item> <item name="fruit">fruits</item> <item name="vegetable">vegetables</item> </item> </root> how delete node value alone ("fruits" "vegetables") retaining attribute values "fruit" "vegetable" in xml in flex. i think should iterate through items. if want delete values items, so: var i:int = 0; each (var node:xml in xml.item.item) { xml.item.item[i] = ""; i++; } you can specify condition: var i:int = 0; each (var node:xml in xml.item.item) { if (node.@name == 'fruit') xml.item.item[i] = ""; i++; }

i have simple object-components design. like: class object1 : public object { component1 _comp1; component2 _comp2; ... componentn _compn; }; is possible expose public: methods of objects1 methods componentk without creating method in object1 calls internally componentk method? i need simple way of doing because it's quite annoying write function every time want expose componentk method. not directly, no. use private inheritance inherit components instead of aggregating them (note private inheritance not express is-a ), , publish of member functions using . this: class object1 : public object, private component1, private component2, ..., private componentn { public: using component1::function1(); using component1::function2(); ... using componentn::functionm(); }; i'm not saying it's best way it, it's a way.

python - A pythonic way to remove all instances of an element without generating a new list -

there many questions similar ( here one ) solutions i've seen use list comprehension or filter , ways generate new list (or new iterator in case of filter in python 3.x). there solutions remove instances modifying list ( like this , and this ), , last resort. however, asking see if there more elegant ("pythonic" question calls it) way of doing it. why disregarding solutions generate new list: iterating on collection of lists, , python allows me modify "current" list iterating over, not replace entirely: >>> ll= [[1,2,3], [2,3,4], [4,5,6]] >>> l in ll: if l[0] == 2: l = [10] >>> ll [[1, 2, 3], [2, 3, 4], [4, 5, 6]] #replacement didn't happen >>> l in ll: if l[0] == 2: l.remove(2) >>> ll [[1, 2, 3], [3, 4], [4, 5, 6]] #modification succeeded you need use slice assignment replace list elements instead of list itself: for l in ll: if l[0] == 2:
