Have you had experience using static methods in your projects?

Yes, static methods are often used in projects to implement functionality that does not depend on the state of an object. For example, utility functions that do not require creating an instance of a class are conveniently made static.

Example in Java:

public class MathUtils {
    public static int add(int a, int b) {
        return a + b;
    }
}

// Call without creating an object:
int sum = MathUtils.add(5, 3);

Static methods simplify calls and can be used for common operations, but they should be used judiciously to avoid violating OOP principles.
