动手动脑兼课后作业2

MethodOverload:

public class MethodOverload {

    public static void main(String[] args) {
        System.out.println("The square of integer 7 is " + square(7));
        System.out.println("
The square of double 7.5 is " + square(7.5));
    }
    public static int square(int x) {
        return x * x;
    }

    public static double square(double y) {
        return y * y;
    }
}

我发现两个函数又相同的名字，但是他们的输入和输出都是不同的，这是函数的重载。
