java中的变量压缩和扩展？

当我单击包含信息的标签时，我想创建一系列新窗口。我希望这些窗口成为孤立的。有没有办法将静态变量传递给类并告诉它继续监视该变量的状态？

基本上我想说

    NewOrphanedWindow.main(StaticClass.ValueToMonitorFromNowOn);

有没有办法做到这一点，或者是否必须在另一侧进行编程？

我基本上想要一个窗口，它将接收变量字符串名称，然后使用该变量字符串来引用实际的静态变量。

I would like to create a series of new windows when I click labels containing information. I want these windows to be orphaned. Is there a way to pass a static variable to a class and tell it to keep monitoring the status of that variable?

Basically I want to say

    NewOrphanedWindow.main(StaticClass.ValueToMonitorFromNowOn);

Is there a way to do this, or does it have to be programmed on the other side?

I basically want a window that will receive a variable String name and then use that variable String to reference the actual static variable.

不确定您到底想做什么，但您可以通过在调用 main 之前设置静态变量来实现它：

NewOrphanedWindow.monitor = StaticClass.ValueToMonitorFromNowOn;

Not sure what exactly you are trying to do, but you can achieve it by setting a static variable before calling main:

NewOrphanedWindow.monitor = StaticClass.ValueToMonitorFromNowOn;

您可以在窗口类中运行一个线程，该线程每 X 秒检查一次变量的值并做出相应的响应：

Thread monitor = new Thread(){
  public void run(){
    while(true){
      //check the value of StaticClass.ValueToMonitorFromNowOn
      try{
        Thread.sleep(1000); //sleep 1 sec
      } catch (InterruptedException e){
        break;
      }
    }
  }
}
monitor.start();

You could run a thread in your window class which checks the value of the variable every X seconds and responds accordingly:

Thread monitor = new Thread(){
  public void run(){
    while(true){
      //check the value of StaticClass.ValueToMonitorFromNowOn
      try{
        Thread.sleep(1000); //sleep 1 sec
      } catch (InterruptedException e){
        break;
      }
    }
  }
}
monitor.start();
