import java.util.function.BiFunction;

/**
 *
 * We can also override static methods by referring methods. In the
 * following example, we have defined and overloaded three add
 * methods.

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

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

    public static float add(float a, float b)
    {
        return a + b;
    }
}

public class MethodReferenceDemo
{
    public static void main(String[] args)
    {
        BiFunction<Integer, Integer, Integer> adder1 = Arithmetic::add;
        BiFunction<Integer, Float, Float> adder2 = Arithmetic::add;
        BiFunction<Float, Float, Float> adder3 = Arithmetic::add;

        int result1 = adder1.apply(10, 20);
        System.out.println(result1);
        
        float result2 = adder2.apply(10, 20.3f);
        System.out.println(result2);
        
        float result3 = adder3.apply(10.6f, 20.8f);     
        System.out.println(result3);
    }
}
