Q1: java图形界面实现图片自动轮播
现在没空帮你写代码了，给你个思路自己写吧！轮播肯定是要切换图片的，并且一般切换的时候是从左到右或从右到左慢慢切的，所以你定义一个图片地址数组，再定义两个jlabel用来显示图片，一个JLabel显示当前图片，另一个显示最新图片！好了，现在你定义一个timer定时器来切换，每隔两秒，就判断一下最新的图片是哪个jlabel，然后将另一个jlabel填充新的图片，然后setlocation()来移动图片，x坐标每次向左几个像素，直至移动完成！这样就是一次轮播，当然你需要将两个jlabel放到一个panel中，免得会出现第二个图片多出一截在慢慢移动的情况
Q2: java：求一段代码，很简单，运行后直接播放一个小视频，播放完后（或者自行定时）立刻自动关闭。
下载JMF（java media framework）
下面是一个例子
import java.awt.BorderLayout;
import java.awt.Component;
import java.net.MalformedURLException;
import java.net.URL;
import javax.media.Manager;
import javax.media.MediaLocator;
import javax.media.Player;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
public class MediaPlayer extends javax.swing.JPanel {
public MediaPlayer(URL mediauUrl) {
initComponents();
setLayout(new BorderLayout());
try {
Player mediaPlayer = Manager.createRealizedPlayer(new MediaLocator(mediauUrl));
Component video = mediaPlayer.getVisualComponent();
Component control = mediaPlayer.getControlPanelComponent();
if (video != null) {
add(video, BorderLayout.CENTER); // place the video component in the panel
}
add(control, BorderLayout.SOUTH); // place the control in panel
mediaPlayer.start();
} catch (Exception e) {
}
}
private void initComponents() {
javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getTopLevelAncestor());
layout.setHorizontalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGap(0, 720, Short.MAX_VALUE)
);
layout.setVerticalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGap(0, 480, Short.MAX_VALUE)
);
}
public static void main(String[] args) {
JFileChooser fileChooser = new JFileChooser();
fileChooser.showOpenDialog(null);
URL mediaUrl = null;
try {
mediaUrl = fileChooser.getSelectedFile().toURI().toURL();
} catch (MalformedURLException ex) {
System.out.println(ex);
}
JFrame mediaTest = new JFrame("Movie Player");
mediaTest.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
MediaPlayer mediaPanel = new MediaPlayer(mediaUrl);
mediaTest.add(mediaPanel);
mediaTest.setSize(800, 700); // set the size of the player
mediaTest.setLocationRelativeTo(null);
mediaTest.setVisible(true);
}
}
Q3: 在Java中如何设置一个定时任务的代码应该怎么写？
指定定时任务的代码如下：
public void schedule(TimerTask task,Date time)
比如,我们希望定时任务2006年7月2日0时0分执行,只要给第二个参数传一个时间设置为2006年7月2日0时0分的Date对象就可以了.
有一种情况是,可能我们的程序启动的时候,已经是2006年7月3日了,这样的话,程序一启动,定时任务就开始执行了.
schedule最后一个重载的方法是
public void schedule(TimerTask task,Date firstTime,long period)
既然号称是定时任务,我们肯定希望由我们来指定任务指定的时间,显然上面的方法就不中用了,因为我们不知道程序什么时间开始运行,就没办法确定需要延时多少.没关系,schedule四个重载的方法还没用完呢.用下面这个就OK了。
Q4: java定时执行问题： 我想让一个Java代码在每小时的第25分钟执行一次的，这个怎么实现？
用spring quartz
public class MyJob{
//这里如果你定义实例变量，可用spring依赖注入,例如
private String job;
public void setJob(String job){
this.job = job;
}
//你要执行的操作
public void execute(){
}
}
spring 配置文件
beans-config.xml
?xml version="1.0" encoding="UTF-8"?
beans xmlns=""
xmlns:xsi=""
xsi:schemaLocation="
"
bean id = "myJob" class="MyJob"
!--如果有注入属性在这里写 property name = "job" value="hihi"/property --
/bean
bean id = "myjobDetail" class = "org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"
property name="targetObject" ref="myJob"
/property
property name="targetMethod" value="execute"/property
/bean
bean id ="triggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean"
property name="jobDetail" ref="myjobDetail"/
!-- 秒 分 小时 天 月 年--
property name="cronExpression" value="0 25 * * * ?"/
/bean
bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"
property name="triggers"
listref bean = "triggerBean"//list
/property
/bean
/beans
在主类中读取定义文件，任务计划自动运行。
public class Test(){
public void static main(String[] args){
ApplicationContext context = new ClassPathXmlApplicationContext("beans-config.xml");
}
}
将配置文件放在该项目的classpath下，一般你放在src目录下即可。也可以自己创建路径放置，在项目的.classpath中可配置下此路径。
最后导入spring的jar包就可以了。
