    Default Constructors & Methods

    Hi, I have to stimulate a bank account, pretty basic
    this is what I'm required to do
    stores the account number (as a long), the name associated with the account, and the balance (as a double);
    Has a constructor which initializes the three values to given parameter values;
    Has accessor methods to get the value of the balance and the account number;
    I've got the first part done, but what does it mean to have a constructor that initializes 3 values? and the accessor methods?
    any help would do!

    This is what I have so far..

    Java Code:
    public class Account {
    
    	
    	private double balance, name;
    	private long acctNumber;
    
    	
    		public Account (double name, long acctNumber, 
                    double balance)
    			{
    			this.name = name;
    			this.acctNumber = acctNumber;
    			this.balance = balance;
    			}
    		
    		public Account ()
    		
    			{
    			balance = 2000.0;
    			
    			}
    	}

    Default

    what does it mean to have a constructor that initializes 3 values?

    It means to write a constructor like the first one you have which initialises this.name etc. (The other constructor doesn't make a lot of sense and should probably be removed.)

    and the accessor methods?

    "Accessor" methods are those that get or set (ie access) certain properties of an object. SO, for instance, an accessor method to get the balance might look like this:

    Java Code:
        /** Returns the balance of this account.*/
    public double getBalance() {
        // ...
    }
