How would you create a utility for working with a library in Java?.

Create a utility class with public static methods that provide a convenient interface for interacting with the library's functionality.

public final class MyLibraryUtils {

    // Private constructor to prevent instantiation
    private MyLibraryUtils() {
        throw new UnsupportedOperationException("Utility class cannot be instantiated");
    }

    /**
     * Example utility method to call a function from the library.
     * Assuming MyLibraryClass is a class from the library.
     */
    public static String processData(String input) {
        // Logic to process data using the library
        // For example:
        // MyLibraryClass libraryObject = new MyLibraryClass();
        // return libraryObject.doSomething(input);
        return "Processed: " + input; // Stub
    }

    /**
     * Another example utility method.
     */
    public static int calculateSomething(int value1, int value2) {
        // Call library functions for calculations
        // For example:
        // return MyLibraryClass.calculate(value1, value2);
        return value1 + value2; // Stub
    }
}

Advantages of this approach:

• Ease of use: No need to create instances of library classes directly.
• Encapsulation: Hides implementation details of working with the library.
• Testability: Utility methods are easier to test.
• Centralized logic: All work with the library is gathered in one place.
• Prevents instantiation: Private constructor ensures that the utility object cannot be accidentally created.
