+calculateCharge():Void

I have an assignment that asks me to write a class:

Code :

---

-------------------------
Computer
-------------------------
-brand:Brand
-price:Double
-quantity:Integer
-totalCharge:Double
-------------------------
+calculateCharge():Void
-------------------------

---

I have the whole class written, I just have no clue how to add the calculateCharge, at least with it asking for void?

Write a method called calculateCharge which has a void return type. I assume the + at the front means it is public. What specific part do you not understand?

I guess how to code it, I have no clue how to do a void return.

So far I have

Code :

---

public double calculateCharge()
{
 
}

---

See Defining Methods (The Java™ Tutorials > Learning the Java Language > Classes and Objects) . Void is nothing, so return nothing.

so it would be

Code :

---

public double calculateCharge()
{
  return 0;
}

---

?

:headdesk:

The main method is a void method. Surely you know what that looks like.

nope, im a complete java noob and am just looking to pass a class haha

See point 2 in the link above, quoted from the link:

---

The return type—the data type of the value returned by the method, or void if the method does not return a value.

---

See the rest of that page (and further) to see method declarations with are defined with void.

To pass a class, or to learn...because these are different goals. Having a goal to learn will usually result in passing (and you come away with something), just doing something to pass and you miss out on the best part.
