Thank upstair, but I have another question, say, I write a DAO, has a method getUsers(int age,boolean sex,String firstName), how do I implement it? Does I implment it by write
{
ResultSet rs=stmt.execute(select firstName,surName,age,sex,detail from users);
//filter the rs
//return a list with the right entities
}

or use the following style:
if(age!=0)
stmtString+="where age="+age;
if(xxxx
xxxxxx

??????
