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");

}

}

}
