当一个catch语句执行以后,其他的子句被旁路,执行从try/catch块以后的代码开始继续。下面的例子设计了两种不同的异常类型: //Demonstratemultiplecatchstatements. classMultiCatch{ publicstaticvoidmain(Stringargs[]){ try{ inta=args.length; System.out.println("a="+a); intb=42/a; intc[]={1}; c[42]=...
Multicatch : You’ll now be able to catch multi exceptions type in one catch block Final Rethow : Allows you to catch an exception type and it’s subtype and rethrow it without having to add a throws clause to the method signature. Often, we have that kind of code : 1}catch(FirstEx...
异常处理程序紧跟在 try 块之后,以关键字 catch 表示: try{// Code that might generate exceptions}catch(Type1 id1){// Handle exceptions of Type1}catch(Type2 id2){// Handle exceptions of Type2}catch(Type3 id3){// Handle exceptions of Type3} 复制 每个catch (异常处理程序)看起来就像是接收...

// This is not acceptable: No concise empty blocks in a multi-block statement try { doSomething(); } catch (Exception e) {} 4.2 块缩进:2个空格 每当开始一个新的块,缩进增加2个空格,当块结束时,缩进返回先前的缩进级别。缩进级别适用于代码和注释。(见4.1.2节中的代码示例) 4.3 一行一个语句 ...
Multi Shared Lock 是一个锁的容器。 当调用 acquire, 所有的锁都会被 acquire,如果请求失败,所有的锁都会被 release。 同样调用 release 时所有的锁都被 release (失败被忽略)。 基本上,它就是组锁的代表,在它上面的请求释放操作都会传递给它包含的所有的锁。 主要涉及两个类: InterProcessMultiLock InterProcess...
