If a catch block handles multiple exceptions, you can separate them using a pipe (|) and in this case, exception parameter (ex) is final, so you can’t change it. The byte code generated by this feature is smaller and reduce code redundancy. Another improvement is done in Compiler analys...

1.检查型异常 (Checked exceptions):从 Exception 类继承的异常都是检查型异常(checked exceptions),客户端必须处理API抛出的这类异常,通过catch子句捕获或是通过throws子句继续抛出(forwarding it outward)。 2.非检查型异常 (Unchecked exceptions):RuntimeException 也是 Exception 的子类,然而,从RuntimeException 继承...

随着Java语言的发展,引入了一些更加便利的特性,比如try-with-resources和multiple catch,具体可以参考下面的代码段。在编译时期,会自动生成相应的处理逻辑,比如,自动按照约定俗成close那些扩展了AutoCloseable或者Closeable的对象。 try (BufferedReader br = new BufferedReader(…);...
