What is the primary task when asked to develop code involving class methods?
The primary task is to call the class methods correctly and determine the result of those calls.
What operator is used to connect the class name and the method name during a class method call?
The dot operator is used to connect the class name and the method name.
What are class methods associated with, as opposed to instance methods?
Class methods are associated with the class itself, not with individual instances of the class.
If a `static` method `computeTotal()` exists in a class named `Calculator`, how would you develop code to call it from another class?
You would call the method using the class name and the dot operator, for example: `Calculator.computeTotal()`.
What is the standard syntax for calling a class method from outside its defining class?
Class methods are typically called using the class name along with the dot operator.
What keyword identifies a class method in its header?
Class methods include the keyword `static` in the header before the method name.
Define 'Class Method' based on the provided text.
A class method is a method associated with a class, not an instance, which includes the `static` keyword in its header.
Inside the `Helper` class, you need to call its own `static` method `printGuide()`. What is the most direct way to write this call?
Since the call is within the defining class, you can call it directly as `printGuide()` without needing to use `Helper.`.
You see the code `Math.random()`. Based on this syntax, what can you determine about the `random()` method?
Because it is called using the class name `Math` and the dot operator, you can determine that `random()` is a class (static) method.
Under what circumstance is using the class name optional when calling a class method?
When the method call occurs in the defining class, the use of the class name is optional in the call.
