What are some examples of generic methods in programming?

Generic methods are methods that allow you to define a method with a placeholder for the data type. For example, in Java, you can create a generic method like this:

public <T> void printArray(T[] array) {
    for (T element : array) {
        System.out.println(element);
    }
}

This method can accept an array of any type.

Can you give me another example?

Sure! Here's another example in C#:

public T GetMax<T>(T a, T b) where T : IComparable<T> {
    return (a.CompareTo(b) > 0) ? a : b;
}

This method returns the maximum of two values of any type that implements the IComparable interface.

What are the benefits of using generic methods?

The benefits include code reusability, type safety, and reducing the need for type casting. They allow you to write more flexible and maintainable code.

Are there any drawbacks to using generics?

Yes, some drawbacks include increased complexity and potential performance overhead in certain scenarios. Additionally, not all types can be used with generics.
