Änderung Ihrer beide Schleifen von diesem

for(int r = 0; r < schedule.length + 1 ; ++r) 
    { 
     row = r; 
     int c; 

     for(c = 0; c < schedule[r].length; ++c); //remove this semi colon 
     { 
       column = c; 


     System.out.print(schedule[r][c]); 

     } 
    } 

dieser

for (int r = 0; r < schedule.length; r++) { 
      if (row == r) { 
       for (int c = 0; c < schedule[r].length; c++) { 
        if (column == c) { 
         System.out.print(schedule[r][c]); 
        } 
       } 
      } 
     }
