  1. 面向对象的程序设计

  2. public class Test0bject { public static void main(String[] args){ Person1 p2=new Person1(); p2.name="沙"; System.out.print(p2.getName()); p2.sleep(); } } 你知道程序的运行结果吗？ class Person1 { public String name; public String getName(){ return name+"有威"; } public void sleep(){ System.out.println("是景山学校的信息技术教师"); } }

  3. public class Test1bject { public static void main(String[] args) { Person p2=new Person(); p2.name="沙"; p2.age=56; System.out.println("我姓"+p2.name); System.out.println("我的姓名是："+p2.getName()); System.out.print(p2.getName()+"的年龄不是"+p2.age); System.out.println("，实际年龄是："+p2.setAge(p2.age)); System.out.print(p2.getName()); p2.sleep(); } } 看看下一页，想想程序的运行结果？

  4. class Person { public String name; public int age; public void setName(String n){ name=n; } public String getName(){ return name+"有威"; } public int setAge(int a){ age=a+1; return age; } public void sleep(){ System.out.println("是景山学校的信息技术教师"); } } 程序的运行结果是？

  5. array b=new array ; //创建array类的对象b array类中对象 b的方法

  6. //比赛总分统计 import java.io.*; public class Pingfen_sum { public static void main(String args[])throws IOException { array b=new array(); //创建对象b b.inputArray(); //访问对象b的方法输入数据 b.outputArray(); //访问对象b的方法输出数据 b.sum(); //访问对象b的方法统计总分 System.out.println("总分："+b.sm); //输出总分 } }
