对象根据参数传递来的条件执行相应的功能。
package org.demo.app2; public class App2 { public void print(String msg, int num) { for (int i = 0; i < num; i++) { System.out.println(msg); } } public void b(String[] strs) { for (int i = 0; i < strs.length; i++) { System.out.println(strs[i]); } } public static void main(String[] args) { String s[] = {"aaa","bbb"}; App2 obj = new App2(); String info = "hahaha"; obj.print("hello world", 5); obj.print(info, 3); obj.b(s); } }
输出结果:
hello world
hello world
hello world
hello world
hello world
