I keep on getting the following error, I've tried modifying the constructor, but I can't get it to work.

This code uses 7 argument Constructor - So, you have to create another constructor which takes seven arguements.

Your Customer constructor requires a Name and an Address, but you have just provided the raw information (last ... zip).
You have to create a Name and Address from the raw data and pass that to Customer

Name n = new Name(last, first);
Address a = new Address(street, city, state, z);
Customer customer = new Customer(n, a, acctNum);
// or just
Customer customer = new Customer( new Name(last, first), new Address(street, city, state, z), acctNum);

that worked, thank you, but now I've run into another problem.

The program compiles.
After I input the information and want to view it. It get random character for Name and Address.

}

For example I would get something like this:
Name@1b09468 Address@1df5a8f 123

The program would display the information properly before I applied the Name and Address class, since it was all under the Customer class.
The Account number does show up properly. It's just the name and address.

Thats because you haven't have implemented the toString method for your objects Address and Name. You need to implement them to define the behaviour of the toString method for your object. For e.g: for the Name object it could be :

public String toString(){
    return this.firstName + " " + this.lastName;
}

In case you do not provide such an information the toString() method as defined in the Object class would be executed, which just returns a string representation of the object concerned.

Note : Incase you are worried from where does the question of the toString method getting called arises in the first place, well that is the method that would be called when you attempt tp print out a copy of that object.
