Java implements a simple example of assigning values to SQL statements

The code itself is simple. When splicing SQL? It's hard to count. It's easy to assign.

 public static void setParam(PreparedStatement pt, List list) throws SQLException{
  for(int i = 0;i<list.size();i++){
   if (list.get(i) instanceof String) pt.setString(i+1, list.get(i).toString());
   else if(list.get(i) instanceof Integer) pt.setInt(i+1, Integer.parseInt(list.get(i).toString()));
   else if(list.get(i) instanceof Short)pt.setShort(i+1, Short.parseShort(list.get(i).toString()));
   else pt.setObject(i+1, list.get(i));
  }
 }
