I need help with these questions

Question 3 - Ok I think this one is ok but I put it up for question 4
[PHP]public class Product
{
public String name;
public double price;

public Product(String name,double price)
{
this.name = name;
this.price = price;
}

public Product()
{
name = "Toaster";
price = 29.95;
}

public String getName()
{
return name;
}

public double getPrice()
{
return price;
}
}
[/PHP]

Question 4 - Now that is all I have done in it! is it ment to be like the EmployeeHarness I have put up?
[PHP]public class ProductHarness
{
public static void main(String[] args)
{

}
}
[/PHP]

EmployeeHarness
[PHP]import javax.swing.JOptionPane;
public class EmployeeHarness
{
public static void main(String[] args)
{
String name = JOptionPane.showInputDialog("Enter your name");
String salary = JOptionPane.showInputDialog("Enter your salary");

Double db = new Double(salary);
double Salary = db.doubleValue();

Employee one = new Employee(name,Salary);
System.exit(0);

}
}
[/PHP]

Question 5 - Ah I need something at the end of the aib program but I dont know wat!
[PHP]public interface BankAccount
{
public void deposit(double amount);
public void withdraw(double amount);
public double getBalance();
}
[/PHP]

[PHP]public class AIBBankAccount implements BankAccount
{
private double balance;

public AIBBankAccount(double amount)
{
balance = amount;
}

public AIBBankAccount()
{
this(0,0);
}

public void deposit(double amount)
}
[/PHP]

Q3 - you are missing setprice method.
Q4 - yes like EmployeeHarness but don't forget its 2 products this time not one. and the price has to be changed.
Q5 - generally if you implement an interface you need to add code to the methods you are implementing, so add public void deposit(double amount); public void withdraw(double amount); public double getBalance(); along with the neccassary code.

Hope that helps!

Well a good habit to get into is to never use double for financial data. This is not just java but all coding languages, using a floating point variable to represent a monetary amount is a very bad idea.

Having a default constructor that makes a product "toaster",29.95 is also a bad idea.
