给出以下Action的Struts.XML配置文件描述（注1：请求为Test/Hello_onPlay.action)package com.yourcompany.action;public class HelloWorldAction{private String message;public String getMessage(){return message;}public void setMessage(String message){this.message = message;}public String onPlay() throws Exception{System.out.println(this.getMessage());return "success";}public String execute() throws Exception{System.out.println(this.getMessage());return "success";}}
举一反三
- public throwable(string message)构造函数包括getmessage()方法，用来返回带参数构造函数创建异常时的 【10】 。
- import java.io.*;public class abc{public static void main(String args[ ]){ AB s = new AB("Hello!"，“world”);System.out.println(s.toString( ));}} class AB {String s1;String s2;AB( String str1 , String str2 ){ s1 = str1; s2 = str2; }public String toString( ){ return s1+s2; }} A: Hello!world B: worldHello!
- 分析下面的程序，输出的结果是？ public class Test { public static void main(String[] args) { final Person p = new Person("张三", 23); p.setName("李四"); p.setAge(24); System.out.println(p); } } class Person { private String name; private int age; public Person() { super(); } public Person(String name, int age) { super(); this.name = name; this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } @Override public String toString() { return "我的姓名是:" + name + ",我的年龄是:" + age ; } }
- 阅读程序，下面的哪个选项是正确的？（ ）。 class ExSuper{ String name; String nick_name; public ExSuper(String s,String t) { name = s; nick_name = t; } public String toString(){ return name; } } public class Example extends ExSuper{ public Example(String s,String t){ super(s,t); } public String toString(){ return name +"a.k.a"+nick_name; } public static void main(String args[]){ ExSuper a = new ExSuper(“First”,“1st”); ExSuper b = new Example(“Second”,“2nd”); System.out.println(“a is”+a.toString()); System.out.println("b is"+b.toString()); } }
- 【填空题】public class ThisTest{ private String name; private int age; public ThisTest() { System.out.println("产生一个新的Person对象。"); } public ThisTest (String name, int age) { this(); this.name = name; this.age = age; } public String getInf() { return "姓名:" + name + ",年龄:" + age; } public static void main(String[] args) { ThisTest per = new ThisTest("张三", 20); System.out.println(per.getInf()); } } 运行结果为:____
