i'm trying initialize 2d array using braces notation follows:

int[][] matrix = {{0, 2, 1}, {1, 2, 3}, {3, 2, 1}}; int[][] out = rotate(matrix);  for(int = 0; < 3; i++){     for(int j = 0; j < 3; j++){         system.out.print(matrix[i][j] + " ");     }     system.out.println(""); }

for output, getting 

0 0 0   0 0 0   0 0 0

can tell me problem?

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
