i have static method(additem) in class, why need wrap additem(..) uses static parenthesis? why need static word? tnx public class something{ static { additem(new dummyitem("1", "a")); additem(new dummyitem("2", "b")); additem(new dummyitem("3", "c")); } private static void additem(dummyitem item) { ...... } } the static block static { .... } defines static initializer. block of code run once, when class initialized. can call static methods in method, not in static intializers. example write public void foo() { something.additem(new dummyitem("1", "a")); } this code called whenever method foo() called.

i new java programming language , had question arrays. string[] arrays hold strings. array[] arrays hold other arrays. object[] array? clearly, these hold object s. but, since object superclass in java, mean object[] array can hold every type of object in java? in other words, can array hold objects child classes of object array created hold? can number[] array hold integer? yes can learn lot trying small program: public class example { public static void main(string[] args) { string string = "string"; integer integer = new integer(1); int integerprimitive = 2; float floatboxed = new float(1.23); float floatprimitive = 1.23f; // can hold different types inheriting object object[] objects = new object[] { string, integer, integerprimitive, floatboxed, floatprimitive }; // can hold inherits number; cannot

i'm debugging code , in order repeatedly making ajax post php script on localhost apache24 server. in simple terms, php script takes integer value , returns different data string depending on input integer. i'm stepping through numerous integer values loop on javascript side, starting @ x=1. i've noticed, however, after ~980 ajax posts, php function stops returning correct data; seems return data x = 980, x continues increment. console.log confirms x value doesn't hang @ 980. i thought maybe script buggy restarted loop @ x = 980 and, sure enough, php script worked fine until x = ~1900, when stopped working again. is there reason php script fails work after ~980 requests? have received no errors on either web side or server side. function interpretdisplay(input_string) { var display = input_string.split("?"); (var x = 0; x < 16; x++) { document.getelementbyid("ids").inn

i know how create dynamic 2d matrix using new , free using delete . since c++ 11 here many new memory features such unique_ptr , array container etc.; nice way create 2d matrix 1 needs not free matrix explicitly using delete operator? one of simplest ways use vector of vectors const int n = 10; const int m = 10; vector<vector<int>> matrix2d(n, vector<int>(m, 0)); // 10x10 zero-initialized matrix matrix2d[0][0] = 42; you of course use single vector , wrap accessor class vector<int> matrix(n * m, 0) // ditto above, needs stride-aware accessors i'll post small example here completeness' sake template <typename t> class matrix2d { std::vector<t> data; unsigned int sizex, sizey; public: matrix2d (unsigned int x, unsigned int y) : sizex (x), sizey (y) { data.resize (sizex*sizey); } t& operator()(unsigned int x, unsigned int y) { if (x >= sizex || y>= sizey)
