    Highschool Java Class Investigation

    Hello everybody I just entered this programming class in my high school, and I'm totally lost.

    They're doing Class and Objects right now.

    I would like to get help on this one problem:

    Develop and implement a class Account that represents a savings account. An Account object should have three attributes: the name of the account, the owner of the account, and the current balance. The class should provide the following constructors behaviors.

    Name(): configures a new account with name "name", owner "owner", and balance 0.
    Name(String s, String t, double n): configures a new account with name s, owner t, and balance n.
    void deposit(double n): adds amount n to the current balance of the associated account.
    void withdraw(double n): subtracts amound n from the current balance of the associated account.
    void close():zeroes out the account balance, sets the owner to "".
    String getAccountName(): returns the name of the associated account.
    String getOwner(): returns the owner of the associated account.
    double getBalance():returns the balance of the associated account.
    void setName(String s): sets the name of the associated account to s.
    void setOwner(String s): sets the owner of the associated account to s.
    String toString(): returns a textual representation of the attributes of the associated account.
    Besides that the teacher doesn't want anyone to add anything into the code, just what it says up there.

    So your "attributes" are your class's data members, and your teacher has given you the declarations of the class's method members. You have the basic structure you need. I expect your reference materials will help you with the rest ... by which you define your constructors and various methods.

    Its my humble suggestion that you do not take help on this one by anyone. If your teacher do not want anyone to add anything into existing code than simply create another class which extend the provided one and write concrete methods there. Infact you should put provided declerations into an interface and than you a class which implements it.

    Again it be much better if you go about solving this one by yourself.

    Basically Account will have three private variables;

    private String name;
    private String owner;
    private double balance;

    The methods specified will set, return of modify these.

    But
    I'm not sure why your teacher wants you to have a special method (Name) that is
    really just doing the job of a constructor. (I may have missed out
    on some "new" java thinking here...or is he planning on using Reflection later ?)
