is possible initialize and/or declare multiple arrays in same line in java? ie. int a, b, c, d, e = 4 works but int[] a, b, c, d, e, = new int[4] doesn't seem work (size of array 4) bear in mind int a, b, c, d, e = 4; is declaring 5 ints initialising 'e'. in same way, int[] a, b, c, d, e = new int[4]; will initialise e. you'd need int[] a=new int[4], b=new int[4], etc... which frankly, isn't worth one-lining...

i writing code update application fetching new dlls ftp site, according manifest file, @ ftp site, specifies versions of each dll. basic idea is, updater program runs @ startup, checks manifest @ ftp site, downloads dll's newer used application, , starts application , shuts down. this leads following problem, not sure of best way handle: want put new dll on ftp site, @ same time updater application instance tries read dll. if delete dll, , copy on new one, updater might not see file, though manifest says should there. i have idea of sort of marker file, act synchronization object, , existence , updater instance can use lock, not moving problem? there still time between checking if lock there, , making lock, in else make lock, , start modifying ftp files. plus, if updater crashes before deleting marker, there no way of telling, whether leftover marker should deleted. edit: saw suggestion upload files folder, , rename folder, since renames supposed atomic operation in ftp, ...

i documenting database, , great have functionality update tables automatically based on current state of database. i know phpmyadmin this, buggy gui doesn't provide many options- end having write script sed find , replace things don't want , add things do. you can accomplish via show tables , show create table command. it may not easy task reconcile has , has not changed. but, basic approach here list of tables in database, , run show create table table_name command full spec on schema. also, use explain command; however, though it's similar, contains higher-level information. i'd argue show create best since that's need see replicate schema. if had more specifics how wanted use information, i'd ammend more information. programming language you're using connect mysql. can use command line info, you'll want intelligent processing in order reconciliation against existing fields in replicated data containers.

i'm getting following output , i've no idea why!? resulting number off 1. i thought double's can handle massive numbers? i'm sure i'm not understanding correctly! appreciated.

i having trouble accessing property members of derived class using base class object. scenario: public class baseclass{ public virtual write(baseclass data){ } } public class derivedclass : baseclass{ private string name: public string name {get {return name} set {name = value;} } public override write(baseclass data){ console.println(data.name); // gives me error here } } the reason have problem accessing properties in derived classes base class not (and more importantly should not ) know them. different derived classes have different set of added properties. making base class aware of counteract important principles of object oriented design. 1 such principle comes mind liskov substitution principle .

i seem having trouble getting deprecated warnings print out, functions declared virtual. i'm using "g++ (gcc) 4.1.1 20061011 (red hat 4.1.1-30)." research shows there might problems in gcc 4.x regarding deprecating pure virtual functions(i.e. class bueller{ virtual int cameron()=0;};), not... i'd guess you'd call them regular... virtual functions. we're on same page... foo.h class foo { void foo_a() __attribute__((deprecated)); //non-virtual virtual void foo_b() __attribute__((deprecated)); //virtual virtual void foo_c() __attribute__((deprecated)) = 0; //pure virtual }; say compiled this, foo.cpp file , main.cpp file using g++. 1)anything uses foo_a() indeed show warning. 2)anything uses foo_b() not show warning. 3)anything inherits foo, implements foo_c , uses not show warning. number 1: works, no problem. number 3: seems known bug/feature.. whatever.. there seems no explination #2 however. perhaps it's tied in #3, although no...
