‘壹’ java中的controlPane()怎么用

ControlPanel ？ JAVA 自带没叫这样的组件。。。。。。。你自己创建的，那看看代码是如何的。

‘贰’ 有关JAVA ResourceBundle.Control类的，谁能看懂这段代码什么意思

没什么意思就是获取bundle实例而已，这在《OSGI IN ACTION》中第一节有讲

‘叁’ java 中怎么实现 一个方法control(int id)，先传ID为4执行,在这个方法执行完后隔2秒再执行这个方法Id 为5

你好！
ya178帮帮团：
用线程执行这个方法，线程可以sleep（2000），休眠后执行第二次。
希望对你有所帮助，望采纳。

‘伍’ java中controller 是什么意思

Controller一般指的是MVC架构里的控制层，是对项目里的功能做统一的调度。java里的着名的MVC框架有struts和springmvc。不过这2个都是javaweb里的框架技术。

‘陆’ java 如何实现ctrl + c等输入希望能给个简单的例子！！谢谢

Java中可通过java.awt.Robot来模拟发送消息：键盘消息，鼠标消息之类的

既然是 CTRL +C
那就先模拟一个ctrl 键 不要发送松开按钮的消息
然后模拟按C键
模拟松开C键
再模拟松开ctrl键

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_C);

robot.keyRelease(KeyEvent.VK_C);
robot.keyRelease(KeyEvent.VK_CONTROL);

‘柒’ springmvc 为什么每个模块都用一个control 而不是用一个control

了先对Controller 有一个初步的印象，以下先定义一个简单的Controller ：
Java代码
1. @Controller
2. public class MyController {
3.
4. @RequestMapping ( "/showView" )
5. public ModelAndView showView() {
6. ModelAndView modelAndView = new ModelAndView();
7. modelAndView.setViewName( "viewName" );
8. modelAndView.addObject( " 需要放到 model 中的属性名称 " , " 对应的属性值，它是一个对象 " );
9. return modelAndView;
10. }

‘捌’ 免安装的jre6如何启用java control panel想在浏览器中启用java，可是又不想通过安装jre6

你在dos下面输入校验的javac 或者Java命令看看是不是可以

‘玖’ java中设计模式中Control、View之间的调用

我觉得你弄错了C和V的关系，应该是这样的：
Control a=new Control();
View b=new View();
b.setSomeListenner(a);
然后，视图b在触发某些事件的时候，比如某个按钮被点击的时候，去调用a的相关方法。

另外楼上说的也行得通，把view当做参数传回去就行嘛。

‘拾’ linux java控制面板怎么打开

Java 7u10 引入了一项功能，该功能能够在 Web 页中包含不可信 Java 应用程序（即由未知发行者进行数字签名的应用程序或尚未由可信证书颁发机构颁发的证书）的情况下管理何时及如何运行此类应用程序。在 Java 控制面板内设置安全级别将确定
在运行不可信的 Java 应用程序之前提示您（"MEDIUM"（中）或 "HIGH"（高）），或
不可信的 Java 应用程序将被阻止，因此无法运行（"VERY HIGH"（很高））
