-->某些表达式的计算也可能从java虚拟机抛出异常,这些表达式在上一小节中已经总结过了;一个显式的的throw语句也将导致异常的抛出。抛出异常也是导致控制权的转换的原因(或者说是阻止statement正常结束的原因)。 如果上述事件发生了,那么这些statement就有可能使得其正常情况下应该都执行的语句不能完全被执行到,那么这些...
doSomething; statementMayCauseException; //可能会抛出异常的语句,若异常没有被catch,则直接抛出,也不会执行到try-catch下面的语句,因为这个异常被系统处理就是打印了异常栈的信息之后就结束了这个程序,也就是结束了这个进程。 doSomething; if(count == 1) throw new Exception1("E1 in try"); if(count ==...

Java的异常处理是通过5个关键字来实现的:try,catch,throw,throws,finally。JB的在线帮助中对这几个关键字是这样解释的: Throws: Lists the exceptions a method could throw. Throw: Transfers control of the method to the exception handler. Try: Opening exception-handling statement. ...
In this example, the method always returns“from finally”and completely ignores thereturnstatement in thetryblock. This could be a very difficult bug to spot, which is why we should avoid usingreturninfinallyblocks. 5.3. Changes What’s Thrown or Returned ...
