This project demonstrates how to convert primitive numeric data types into string representations for data transmission or messaging purposes.

• Create an int variable to store a secret access code.
• Convert this numeric value into a String object.
• Print the resulting string to the console.

• Language: Java 23 (Current version).
• IDE: IntelliJ IDEA.
• Concepts: Primitive vs. Object types, Clean Code (Explicitness).

This task applied the clean code explicit conversion principle. Instead of relying on an implicit conversion (e.g. "" + number), which is considered a "code smell", the String.valueOf() method was used.

1. Readability: It clearly states the intent to transform data.
2. Performance: It avoids creating temporary StringBuilder objects that can occur during string concatenation in some JVM versions.
3. Safety: This approach ensures that the conversion is handled by the standard library's optimized methods.

Secure access code for message: 774109
Length of the shared code: 6

package com.yurii.pavlenko;

public class Task_16_App {
    public static void main(String[] args) {
        // 1. Create a secret access code as an integer
        int accessCode = 774109;
        // 2. Convert the integer to a String explicitly (Clean Code approach)
        String sharedCode = String.valueOf(accessCode);
        // 3. Output the result to the screen
        System.out.println("Secure access code for message: " + sharedCode);
        // Let's verify it's a String by checking length (int doesn't have .length())
        System.out.println("Length of the shared code: " + sharedCode.length());
    }
}
