7,783 PointsI do not know why my answer is still wrong. since the connectionBulder class has a default constructor please help
here is the my answer 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 Connection("sqlite","languages","th_user","mysuperlongpassword"); Connection c = new Connection.ConnectionBuilder().withJdbcVendor("sqlite").withDb("languages").withUser("th_user","mysuperlongpassword").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;
this.dbName = builder.dbName;
this.username = builder.username;
this.password = builder.password;
}
public static class ConnectionBuilder{
private String jdbcVendor;
private String dbName;
private String username;
private String password;
public ConnectionBuilder(){}
public ConnectionBuilder withJdbcVendor(String jdbcVendor) {
this.jdbcVendor = jdbcVendor;
return this;
}
public ConnectionBuilder withDb(String dbName) {
this.dbName = dbName;
return this;
}
public ConnectionBuilder withUser(String username, String password) {
this.username = username;
this.password = password;
return this;
}
public Connection build() {
return new Connection(this);
}
}
}
import com.teamtreehouse.builder.Connection;

13,520 Pointsyour Connection object declaration should look like this
Connection c = new ConnectionBuilder()
.withJdbcVendor("sqlite")
.withDb("languages")
.withUser("th_user","mysuperlongpassword")
.build();
