Enter here.");Scanner bike = new Scanner(System.in);double m = bike.nextDouble(); Scanner av = new Scanner(System.in);int cost = av.nextDouble();}

Let's examine the question: What is one way to clean up the following spaghetti-like code?
public static void main(String[] args) {System.out.println("Welcome to your gas and CO2 emission conversion buddy!");System.out.println("How many miles did you bike this week? Enter here.");Scanner bike = new Scanner(System.in);double m = bike.nextDouble(); Scanner av = new Scanner(System.in);int cost = av.nextDouble();}

Option 1: Having a common indentation for classes, methods, and loops. While consistent indentation improves readability, it does not address the root problem of spaghetti code, which is often about multiple tasks happening in a single block or line. So this helps formatting but not the structural cleanup.
Option 2: Changing the casing of all terms in the code to lowercase. This is largely a superficial stylistic change that does not improve readability or structure in a meaningful way, and it can actually obscure standard naming conventions in Java (like class names) or cause confusion. Therefore it’s not a real cleaning strategy.
Option 3: Ensuring that there is only one small task in every line of code. This aligns with the single-responsibility principle and the broader idea of breaking complex statements into simpler, focused actions. By refactoring to separate concerns, you reduce coupling and make the code easier to read, test, and maintain. This directly targets spaghetti-like structure by decomposing operations across lines and methods.
Option 4: Ensuring that only one data type has been used in the code. Forcing a single data type is impractical and can degrade correctness and clarity, since different data types are needed for different inputs and operations (strings, doubles, ints, etc.). This option would likely hamper the code’s functionality rather than clean it up.
