Do you understand what a method is, and can you analyze and understand what is embedded in it without documentation?

A method is a function associated with an object or class that operates on the data of that object. To understand what a method does without documentation, you should:

• Study its name — it often reflects its purpose.
• Look at its parameters — what data it accepts.
• Analyze the method body — what operations it performs, what variables it uses.
• Pay attention to the return value.

For example, if a method is called calculateTotal, takes a list of products, and returns a number, it probably sums up the cost of the products. Understanding the code and context helps to grasp the logic without documentation.
