实现简易计算器，分别实现两个整数、三个浮点数的加法运算Counter类代码：package com.bdqn;public class Counter { public void addCounter(int n, int m){ System.out.println(n+m);} public void addCounter(double a ,double b,double c){ System.out.println(a+b+c);} } CounterTest类代码：package ...
CounterTest类代码: packagecom.bdqn;publicclassCounterTest {publicstaticvoidmain(String[] args) { Counter c=newCounter(); c.addCounter(1,2); c.addCounter(1.1,2.2,3.3); } } 运行结果:
