Java之方法重载篇（我重载了，你要如何来调用我。。）

 

# **一、课前引言**

• 请看一下代码，你发现什么特殊之处了吗？

    public class MethodOverload {
        public static void main(String[] args) {
            System.out.println("The square of integer 7 is " + square(7));
            System.out.println("\nThe 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;
        }
    }
  

二、如何重载？如何调用？
