What impact does using Java functions have on maintainability and code readability?

The advantage of Java functions is to improve the maintainability and readability of the code, which is embodied in modularity, reusability, and low coupling. At the same time, it makes the code clear and logically structured, and improves readability through indentation and comments. Readability. For example, the calculateAverage() function separates the average calculation logic, makes it reusable, and has low coupling with the main method. The code is also clearer and readable.

How Java functions improve maintainability and code readability

Using functions in Java brings undeniable Maintainability and code readability benefits. It achieves these benefits by breaking down blocks of code into independent, reusable units.

Maintainability

• Modularization: Functions divide the code into smaller, manageable modules, making it easier Identify and modify specific features.
• Reusability: Functions can be used multiple times in different contexts, reducing code duplication and maintenance overhead.
• Low coupling: Functions have well-defined interfaces so that they can be changed independently of other code. This reduces the impact on the overall program.

Code readability

• Clear and concise: Functions clearly define their purpose and responsibilities, making the code easy to understand .
• Logical structure: Function organizes code to reflect business logic, making the program flow easier to track.
• Indentation and comments: Functions use indentation and comments to clearly describe the code flow, improving code readability and understandability.

Practical Case

Consider the following Java code, which uses a function to calculate the average of two numbers:

public class AverageCalculator {

    public static double calculateAverage(int num1, int num2) {
        return (num1 + num2) / 2.0;
    }

    public static void main(String[] args) {
        int num1 = 10;
        int num2 = 15;

        double average = calculateAverage(num1, num2);
        System.out.println("Average: " + average);
    }
}

Maintainability improvement:

• ##calculateAverage() function separates the average calculation logic from the main() method, making it easier Easy to update and maintain.
The function is reusable and can calculate the average in different contexts, avoiding duplication.
• Weaker coupling means that changes to
• calculateAverage() will not have an impact on the main() method.

Enhanced code readability:

• calculateAverage() clearly defines its responsibilities, making the code easy to interpret.
Functions are logically organized into steps for calculating averages, clearly reflecting the business process.
• Indentation and comments make code more readable and understandable.
