在Java中处理InterruptedException（java interruptedexception）
以下处理方式有什么区别InterruptedException？最好的方法是什么？
try{ //...} catch(InterruptedException e) { Thread.currentThread().interrupt(); }要么
try{ //...} catch(InterruptedException e) { throw new RuntimeException(e);}编辑：我也想知道这两种情况在哪些情况下使用。
答案1
小编典典以下处理InterruptedException的方式之间有什么区别？最好的方法是什么？
你可能会问这个问题，因为你已经调用了throw方法InterruptedException。
首先，你应该throws InterruptedException了解它的含义：方法签名的一部分以及调用你正在调用的方法的可能结果。因此，首先要包含一个事实，即an InterruptedException是方法调用的完全有效结果。
现在，如果你正在调用的方法抛出此类异常，那么你的方法应该怎么做？你可以通过考虑以下因素找出答案：
对于你要实现的方法抛出异常有意义InterruptedException吗？换句话说，InterruptedException调用你的方法是否明智？
如果是，那么throws InterruptedException应当成为你的方法签名，你应该让异常繁殖（即完全不抓住它）。
示例：你的方法等待网络中的值来完成计算并返回结果。如果阻塞的网络调用抛出InterruptedException你的方法将无法以正常方式完成计算。你让InterruptedException传播。
int computeSum(Server server) throws InterruptedException { // Any InterruptedException thrown below is propagated int a = server.getValueA(); int b = server.getValueB(); return a + b;}如果为no，则不应使用声明你的方法，throws InterruptedException并且（必须！）应捕获异常。现在，在这种情况下要牢记两件事：
- 有人打断了你的线程。有人可能想取消该操作，优雅地终止程序或执行其他操作。你应该对那个人彬彬有礼，并毫不费力地从方法中返回。
- 即使在线程被中断的情况下，即使你的方法可以设法产生合理的返回值，InterruptedException也可能仍然很重要。特别是，调用你的方法的代码可能会对执行方法期间是否发生中断感兴趣。因此，你应该通过设置中断标志来记录发生中断的事实：
Thread.currentThread().interrupt()
示例：用户要求打印两个值的总和。Failed to compute sum如果无法计算总和，则打印“ ”是可以接受的（并且比使程序由于栈跟踪而崩溃更容易InterruptedException）。换句话说，使用声明此方法没有任何意义throws InterruptedException。
void printSum(Server server) { try { int sum = computeSum(server); System.out.println("Sum: " + sum); } catch (InterruptedException e) { Thread.currentThread().interrupt(); // set interrupt flag System.out.println("Failed to compute sum"); }}到现在为止应该很清楚，只是做throw new RuntimeException(e)一个坏主意。呼叫者不太礼貌。你可以发明一个新的运行时异常，但根本原因（有人希望线程停止执行）可能会丢失。
其他例子：
实现Runnable：你可能已经发现，的签名Runnable.run不允许重新抛出InterruptedExceptions。好吧，你已经签署了实施计划Runnable，这意味着你已经注册了对“可能”的处理InterruptedExceptions。选择其他界面（例如）Callable，或按照上面的第二种方法。
呼叫Thread.sleep：你正在尝试读取文件，而规范说你应该尝试10次，中间间隔1秒。你打电话Thread.sleep(1000)。因此，你需要处理InterruptedException。对于这样的方法tryToReadFile，说“如果我被打断了，我将无法完成尝试读取文件的动作”是很有意义的。换句话说，该方法抛出异常是有意义的InterruptedExceptions。
String tryToReadFile(File f) throws InterruptedException { for (int i = 0; i < 10; i++) { if (f.exists()) return readFile(f); Thread.sleep(1000); } return null;}
C3P0:java.lang.InterruptedException: sleep interrupted
好好的就报异常了～～
