你可以把ChuckNorris隐藏起来，也可以把他封装起来，也可以把他吞下去……

try {doChuckAction();} catch(ChuckNorrisException cne){/*做其他事情*/}

Two fundamental problems with exception handling in Java are that it uses the type of an exception to indicate whether action should be taken based upon it, and that anything which takes action based upon an exception (i.e. "catch"es it) is presumed to resolve the underlying condition. It would be useful to have a means by which an exception object could decide which handlers should execute, and whether the handlers that have executed so far have cleaned things up enough for the present method to satisfy its exit conditions. While this could be used to make "uncatchable" exceptions, two bigger uses would be to (1) make exceptions which will only be considered handled when they're caught by code that actually knows how to deal with them, and (2) allow for sensible handling of exceptions which occur in a finally block (if a FooException during a finally block during the unwinding of a BarException, both exceptions should propagate up the call stack; both should be catchable, but unwinding should continue until both have been caught). Unfortunately, I don't think there would be any way to make existing exception-handling code work that way without breaking things.

抛出的任何异常都必须扩展Throwable，因此总是可以捕获它。所以答案是否定的。

如果你想让它难以处理，你可以重写方法getCause()， getMessage()， getStackTrace()， toString()抛出另一个java.lang.ChuckNorrisException。

在构造函数中，可以启动一个反复调用originalThread的线程。停止(ChuckNorisException.this)

线程可以重复捕获异常，但会一直抛出异常，直到异常死亡。

这个主题的另一个变体是，您可以从Java代码抛出未声明的受控异常。由于它没有在方法签名中声明，所以编译器不会让您捕获异常本身，尽管您可以将其作为java.lang.Exception捕获。

这里有一个帮助类，它允许你抛出任何东西，无论是否声明:

public class SneakyThrow {
  public static RuntimeException sneak(Throwable t) {
    throw SneakyThrow.<RuntimeException> throwGivenThrowable(t);
  }

  private static <T extends Throwable> RuntimeException throwGivenThrowable(Throwable t) throws T {
    throw (T) t;
  }
}

现在扔SneakyThrow。溜(新ChuckNorrisException ());抛出ChuckNorrisException，但编译器抱怨

try {
  throw SneakyThrow.sneak(new ChuckNorrisException());
} catch (ChuckNorrisException e) {
}

如果ChuckNorrisException是一个受控异常，则捕获没有抛出的异常。

在finalize中调用System.exit(1)，并抛出来自所有其他方法的异常副本，以便程序退出。
