In this problem, you will implement the Recipe class that manages object state through fields such as ingredients.

Explanation: Calling Methods with Arguments

In this problem, you learned methods that receive arguments and methods without return values.

Key Learning Points

1. Methods with Arguments: Format public void methodName(type argument)
2. void Type: Use void when there's no return value
3. Field Update: Can change field values inside methods

Code Example Explanation

public void addIngredient(String ingredient) {
    If (ingredients.isEmpty()) {
        Ingredients = ingredient;  // First ingredient
    } else {
        Ingredients += ", " + ingredient;  // From second onward
    }
}

This method:

• void: No return value
• String ingredient: Receives string argument
• ingredients +=: Adds to existing string

Next Steps

Next, let's combine with methods that have return values!
