i've been trying to figure out this exercise all day.. the first exercise was hard enough, but i finally figured that one out, but this one is really confusing me..



nothing i do seems to work. and its really frustrating me that seem to understand wtf i have to do.. if anyone could offer tips, i would very much appreciate it

Is this a java programming problem? Post your code and your questions.

yes it is. and the code i need to make is for that picture, but i cannot figure out what the right code is

[Norm]

There must be some ideas in your class notes. I'm not familiar with what the picture represents.

Here are the first steps;

public interface Person { ... }
public class Employee implements Person { ... }
public class Manager extends Employee { ... }

You fill in the details ...

kind regards,

Jos

hey jos, thanks for this. but some of them are set to private and such
• +: public, -: private, #:protected, ~:default
• Employee is paid a rate per hour.
• Manager is paid above + bonus.

does that make things more complicated or? in any case, i'll try to work it out with how you suggested, and let you know if i got it working

[JosAH]

Those +, -, # and ~ thingies are only another notation for private/public/etc. member variables and methods. It's a one-to-one translation to Java code; there's nothing complicated about it.

kind regards,

Jos

Oh come on, since you can clearly read the diagram then why have you not at least got the skeleton of the classes and interface in place?

[lonewolf1994]

this is what i have done so far for the employee class
package payroll;

public class Employee implements Person {

private int hoursWorked;
private float payRate;

public int gethoursWorked(){
return this.hoursWorked;
}

public void sethoursWorked(int hoursWorked){
this.hoursWorked = hoursWorked;

}

private float getpayRate(){
return this.payRate;
}

private void setpayRate(float payRate){
this.payRate = payRate;
}

}

i got one question, the "get wage" is confusing me a bit... do i just do a getter for both classes and no setters?

[Tolls]

Yes, as that's what the design says.

Note the capitalisation of the method names, though.
Yours are incorrect as they stand.

sorry, can you please elaborate on which i need to capitalize please?

ah.. i noticed i was doing it wrong! i saw the ~ as a -.. so they aren't private... *facedesk*

Those funny characters have nothing to do with capitalization whatsoever; Tolls was talking about, say, a member variable 'foo'; its getter and setter methods should look like getFoo() and setFoo( ... ). Check your method names again and especially their CamelCase capitalization.

kind regards,

Jos

Yes, gethoursWorked != getHoursWorked (which is what the design in the first post is expecting).
