现在,我的主要是用10行调用一个gui.根据这些行中有多少行有文本,调用9个类中的1个(两行必须有文本).被调用的类执行计算,我希望将进度条绑定到.以下是其中一个被调用类的示例(每个类都相似,但足够不同以保证新类.)我认为问题违反了EDT规则,但我在其上看到的所有示例都涉及到论点.运行代码时会出现框架,但在完成所有计算之前,进度条不会更新.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class twoLoan extends JFrame {
static JFrame progressFrame;
static JProgressBar progressBar;
static Container pane;
double amountSaved = 0;
int i = 0;
public void runCalcs(Double MP, Double StepAmt,
Double L1, Double L2, Double C1, Double C2,
Double IM1, Double IM2, Double M1Start, Double M2Start) {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
}
int iterations = (int) (MP - (M1Start * M2Start));
//Create all components
progressFrame = new JFrame("Calculation Progress");
progressFrame.setSize(300, …我通过使用Executor玩SwingWorker的多线程,我在那里错误地从Vector中识别出错误的元素,看起来像这个代码相当忽略了Vector中的元素不存在
我的问题 - >如何/有可能以某种方式捕获此异常
简单的输出
run:
Thread Status with Name :StartShedule, SwingWorker Status is STARTED
Thread Status with Name :StartShedule, SwingWorker Status is DONE
Thread Status with Name :StartShedule, SwingWorker Status is STARTED
Thread Status with Name :StartShedule, SwingWorker Status is DONE
Thread Status with Name :StartShedule, SwingWorker Status is STARTED
Thread Status with Name :StartShedule, SwingWorker Status is DONE
BUILD SUCCESSFUL (total time: 11 seconds)
通过取消注释
//changeTableValues1(); // un-comment for get ArrayIndexOutOfBoundsException
一切都正确,我得到ArrayIndexOutOfBoundsException并输出
run:
Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: …目前我有两个SwingWorker线程在后台工作.如果发生异常,该方法将停止工作,但该线程仍然运行.
如何停止执行并杀死doInBackground()发生异常的线程？
this.cancel(true)不要破坏/关闭线程.我怎样才能做到这一点？
@Override
protected Boolean doInBackground() throws Exception {
try {
while (true) {
//some code here
return true;
}
} catch (Exception e) {
this.cancel(true); //<-- this not cancel the thread
return false;
}
}
我在Netbeans的调试中看到了这些线程.
