java - run() method doesn't get called from a Runnable implementation -


i'm having trouble runnable , thread implementations. have abstract class, can not modified:

abstract class ordenador {      ...      protected ordenador(string nombre, int[] array) {         ...     }      protected void escribir() {         ...     }      protected abstract void ordenar();  }

and sort algorithm inherit class above , implements run() method, call sorting one.

class burbuja extends ordenador implements runnable {      protected burbuja(string nombre, int[] array) {         super(nombre, array);     }      protected void ordenar() {         ....     }      public void esperar() {         try {             thread.sleep(1000);         } catch (interruptedexception ex) {             ex.printstacktrace();         }     }      public void run() {         this.ordenar();     } }

finally have main class creates random array , create new burbuja object sort array. problem when calling b.join() array stay same de ordenar() method doesn't called.

class aplicacion {      public static void main(string[] args) {         ...          burbuja burbuja = new burbuja("burbuja", array);         thread b = new thread(burbuja);         ...          try {             b.join();             s.join();             ... more sorting algorithms...         } catch (exception ex) {             ex.printstacktrace();             system.exit(-1);         }          system.out.println("");         burbuja.escribir();        } }

i tried modificating parts of code doesn't work neither.

you have call start() method on thread object

java - pagination of xlsx file to XSSFworkbook using apache POI -

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
