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。

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");
    }
  }
}
