Just beginning to start implementing Super and Sub classes to our projects but I'm having a bit of a problem creating the Subclass constructors to allow for different types of accounts but following the same rules as the Superclass.
Here is the constructor error I'm having.

In your Account
class you have specified a constructor that takes multiple arguments: firstName, lastName, accountNumber etc..
In the constructor of the subclass you have to invoke the constructor of the super class -> super()
A little example:
class Person {
public String name;
/*constructor*/
public Person(String name) {
this.name = name;
}
}
class Student extends Person {
public String studentNumber;
/*constructor*/
public Student(String name, String studentNumber) {
/* invoke super constructor. The parameters have to match the
* parameters specified in the constructor of Person
*/
super(name);
/* Now set the properties that only belongs to Student */
this.studentNumber = studentNumber;
}
}
