详解Java中多线程异常捕获Runnable的实现

package step5.exception;  import java.util.Vector; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import java.util.concurrent.TimeUnit;  import com.autonavi.pds.core.incre.impl.LayerInitTask;  public class ThreadException {    public static void main(String[] args) {     try {       Vector<String> errRet = new Vector();       ExecutorService pool = Executors.newFixedThreadPool(6);       for (int i = 0; i < 6; ++i) {         pool.execute(new LayerInitTask(i, errRet));       }       pool.shutdown();       pool.awaitTermination(1, TimeUnit.DAYS);              if (errRet.size() > 0) {         System.out.println("根据返回值捕获：exception");         throw new RuntimeException( "入库失败！");       }            } catch (Exception e) {       System.out.println("根据抛出异常捕获：exception");       throw new RuntimeException( "入库失败！");     }     System.out.println("-----入库成功，发成功完成工作邮件--------");   }  }
