java - Syntax problems in Matrix addition and multipication program -

-

i trying compile program entered 2 3*3 arrays , multipyling , adding both of them. giving me errors @ end due not running. cant remove these errors , need regarding how can remove them.

import java.util.scanner; public class matrix{ public static void main(string [] args){ int [][]= new int [3][3]; int b [][]= new int [3][3]; int c [][]= new int [3][3]; int d [][]= new int [3][3]; scanner in= new scanner(system.in);  system.out.println("enter numbers in first matrix"); for( int r=0; r<3; r++){     for( int c=0; c<3; c++){ [r][c]= in.nextint(); } }  system.out.println("matrix 1 : ");   for(int = 0; < 3; i++) {   for(int j = 0; j < 3; j++) {   system.out.print(" "+ a[i][j]);   }   system.out.println();   }    system.out.println("enter numbers in 2nd matrix"); for( int n=0; n<3; n++){     for( int m=0; m<3; m++){  b [n][m]= in.nextint(); } }  system.out.println("matrix 2 : ");   for(int k = 0; k < 3; k++) {   for(int l = 0; l < 3; l++) {   system.out.print(" "+b[k][l]);   }     system.out.println();   }    //for multiplication of matrices   for(int f = 0; f < 3; f++) {   for(int s = 0; s < 3; s++) {   for(int d = 0; d < 3; d++){    c[f][s] += a[f][d]*b[d][s];   }   }    }   system.out.println("multiplication of both matrix : ");   for(int x = 0; x < 3; x++) {   for(int y = 0; y < 3; y++) {   system.out.print(" "+c[x][y]);   }     system.out.println();   }   }  // addition of both matrices  for(int w=0; w < 3; w++) {   for(int u=0; u < 3; u++) { d[w][u] = a[w][u]+b[w][u]; } }  system.out.println("addition of both matrix : ");   for(int p = 0; p < 3; p++) {   for(int q = 0; q < 3; q++) {   system.out.print(" "+ d[p][q]);   }     system.out.println();   }   } }

use ide , indent program. see issues. have 2 issues issues:

  1. you have parenthesis. not tell where.
  2. you have "d" defined twice variable.

again, it time download , use ide , indent code.

c# - MSAA finds controls UI Automation doesn't -

i'm working on automating windows application. i'm using teststack white framework. i've hit problem. program has 'window' object cannot see inside of. white shows no controls inside of it. inspect.exe shows no controls inside of either when running in ui automation mode. if switch inspect msaa see controls inside fine. there anyway me use msaa c# handle on these controls? if can identify msaa functions need, can use p/invoke call them c#. here's example article doing msaa: http://www.codeproject.com/articles/38906/ui-automation-using-microsoft-active-accessibility also, pinvoke.net can used identify iaccessible (msaa) functions: http://www.pinvoke.net/search.aspx?search=iaccessible&namespace=[all] here's answer along lines: msaa com-based? finally, alternative p/invoke, might able use tlbimp.exe create wrapper assembly oleacc.dll, , access msaa functions through it. i'm not sure if works msaa, it's worth try. as e
