java - Get running total of numbers? -


i desperately trying last column of code add middle column numbers in running total.. seems start @ 1 already.

also, side question: when input 12.. 11 results, due "y" starting @ 1. there anyway fix in loop?

import javax.swing.joptionpane; public class project     {     public static void main( string[] args )         {         string input = joptionpane.showinputdialog( "how many fibonacci numbers                                                       wish see?" +                                                      "\n" + "choose 1-50!");          int numfib = integer.parseint( input );         int numbers[] = new int[numfib];         int fibonacci[] = new int[50];          for( int index = 1; index < numbers.length; index++ )             {             numbers[index] = index;             }         for( int x = 0; x < numbers.length; x++ )             {             if( x == 0 )                 {                 fibonacci[0] = 0;                 }             if( x == 1 )                 {                 fibonacci[1] = 1;                 }             if( x > 1 )                 {                 fibonacci[x] = fibonacci[x-2] + fibonacci[x-1];                 }             }         system.out.println( "number" + "\t" + "fibonacci number" + "\t" +                                                "running total of fns" );         for( int y = 1; y < numbers.length; y++ )             {              int total = fibonacci[y] + fibonacci[y - 1];              system.out.println( numbers[y] + "\t" + fibonacci[y - 1]                                  + "\t" + "\t" + "\t" + total );             }         }     }

to start start y zero:

int total = 0; for( int y = 0; y < numbers.length; y++ ) {     total += fibonacci[y];     system.out.println( numbers[y] + "\t" + fibonacci[y]                                  + "\t" + "\t" + "\t" + total ); }  total -= fibonacci[0] + fibonacci[numbers.length-1];

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...

i'm working on adding multiple querystring , doesn't seem work. i've found codes seems work others might i'm missing something. i want like: http://mydomain.com/board/?getyear=2013&getsometext2=sometext to http://mydomain.com/board/2013/sometext/ i added code below functions.php file. doesn't seem work should though. this works. echoing querystring gets both variable without problem. http://mydomain.com/board/2013/sometext/ but doesn't. tested querystring vis isset() seems nothing being set/get http://mydomain.com/board/2013/ function add_query_vars($vars) { $vars[] = "getyear"; $vars[] = "getsometext2"; return $vars; } add_filter('query_vars', 'add_query_vars'); function add_rewrite_rules($arules) { $anewrules = array('board/([^/]+)/([^/]+)/?$' => 'index.php?pagename=board&getyear=$matches[1]&getsometext2=$matches[2]'); $arules = $a...
