Solution 1

Easy way to use "toString()" in your Category Class, and you don't need to create any method to convert Java Object into SQL String.

solved look this code create by myself

Java

Autos aut=new Autos();
       aut.setAuto("Auto1");
       aut.setColor("Negro");
       aut.setId_auto(12);
       aut.setPeso(10000);
       aut.setTama("Grande");

   Field[] fields = aut.getClass().getDeclaredFields();
   String campos="";
   String valores="";
   for (int i = 0; i < fields.length; i++) {
      try{

           String name = fields[i].getName();
           String value = fields[i].get(aut).toString();
           if(i!=0){
               campos=campos+",";
               valores=valores+",";
           }
           if(fields[i].get(aut) instanceof String){
               valores=valores+"'"+value+"'";
           }
           else{
               valores=valores+value;
            }
           campos=campos+name;
       } catch (IllegalAccessException ex) {}
   }
     String sql="insert into dbo."+aut.getClass().getSimpleName().toLowerCase()+"("+campos+")values("+valores+");";
     System.out.println(sql);
