java多线程编程之捕获子线程异常示例

通过try catch是无法捕获子线程异常的，Thread对象提供了setUncaughtExceptionHandler(Thread.UncaughtExceptionHandler eh)方法用来获取线程中产生的异常。

 

复制代码代码如下:

package threads;

 

import java.lang.Thread.UncaughtExceptionHandler;

public class TextException
{
  public static void main(String[] args)
  {
    Test test = new Test();
    test.setUncaughtExceptionHandler(new UncaughtExceptionHandler()
    {
      public void uncaughtException(Thread t, Throwable e)
      {
        System.out.println(t.getName() + " : " + e.getMessage());
        // TODO
      }
    });
  }

  public static class Test extends Thread
  {
    public Test()
    {
    }

    public void run()
    {
      throw new RuntimeException("just a test");
    }
  }
}
