14,132 PointsHibernate Basis
Can you please explain what wrong with my solution. This is Hibernate Basis 'Using the Builder Pattern.
The ConnectionBuilder takes no arguments ... so so i am not sure why I keep getting this message "ummer! You haven't properly called the ConnectionBuilder
constructor"
Thanks
Bummer! You haven't properly called the ConnectionBuilder
constructor
import com.teamtreehouse.builder.Connection; import com.teamtreehouse.builder.Connection.ConnectionBuilder;
public class Application { public static void main(String[] args) { // TODO: User the builder here instead Connection c = new ConnectionConnectionBuilder() .withUser("th_user", "mysuperlongpassword") .withDb("languages") .jdbcVendor9("sqlite") .build(); } }
package com.teamtreehouse.builder;
public class Connection {
private String jdbcVendor;
private String dbName;
private String username;
private String password;
public Connection(String jdbcVendor, String dbName, String username, String password) {
this.jdbcVendor = jdbcVendor;
this.dbName = dbName;
this.username = username;
this.password = password;
}
public Connection(ConnectionBuilder builder) {
this.jdbcVendor = builder.jdbcVendor;
