How do I implement function overloading in Java?

Function overloading in Java allows you to define multiple methods with the same name but different parameters. You can achieve this by changing the number or type of parameters.

Can you give me an example of function overloading?

Sure! Here's a simple example:

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

In this example, the add method is overloaded with two different parameter types.

What happens if I use the same parameter types?

If you use the same parameter types, the compiler will throw an error because it won't be able to distinguish between the methods. Each overloaded method must have a unique parameter list.

Are there any limitations to function overloading?

Yes, function overloading is limited to the method signature. You cannot overload methods based solely on return type or access modifiers.
