推荐答案

在Java中，未处理的异常计算到线程的顶端在那里他们被抛出。 Java允许您安装线程级别未捕获异常处理程序。据我所知，当没有指定默认异常处理程序时，行为没有被Java规范定义。 Sun的JDK观察到的默认行为是将异常消息及其堆栈跟踪打印到stderr。

In Java unhandled exceptions perculate to the top of the thread in which they were thrown. Java allows you to install a thread-level uncaught exception handler. The behavior when there is no default exception handler specified, as far as I know, is not defined by the Java specification. Sun's JDK observed default behavior is to print the exception message and its stack trace to stderr.
