hierarchy, to allow programs to use the idiom “} catch (Exception e) { ” (§11.2.3) to catch all exceptions from which recovery may be possible without catching errors from which recovery is typically not possible. 已经不难看出,Java本身设计思路就是希望大家catch Exception就足够了,如果有Erro...

Exception是异常,异常则是可以通过编码解决的。 Error与Exception的相同点: Error与Exception类都是Throwable的子类 Exception类是所有异常的超类。 Java所有的异常在寻找父类的时候最终都能找到Exception类。 异常的分类 java.lang.Exception类是所有异常的超类,主要分为以下两种: ...
if(obj==null){thrownewIllegalArgumentException("obj can not be null"); 我们可以在同一个catch子句中捕获多个异常吗? 答案是当然可以,不过如果在同一个catch子句中捕获的这些异常都直接或间接继承自同一父类,那么就只能在catch子句中捕获父类了。
