从图中可以看出,类Throwable有两个直接子类:Error和Exception。Error类对象(如动态连接错误等),由Java虚拟机生成并抛弃(通常,Java程序不对这类例外进行处理);Exception类对象是Java程序处理或抛弃的对象。它有各种不同的子类分别对应于不同类型的例外。其中类RuntimeException代表运行时由Java虚拟机生成的例外,如算术...
You can throw any type of exception from your code, as long as your method signature declares it. You can also make up your own exceptions. Exceptions are regular Java classes that extends java.lang.Exception, or any of the other built-in exception classes. If a method declares that it t...

in main,catchException: java.lang.ArithmeticException: / by zero 3.2 try-catch程序块的执行流程以及执行结果 相对于try-catch-finally程序块而言,try-catch的执行流程以及执行结果还是比较简单的。 首先执行的是try语句块中的语句,这时可能会有以下三种情况: ...
So in general: if an exception occurs, there's usually no benefit in pretending it didn't. If your method can't deal with it, that's usually a good sign that you need to throw it up to the caller. So when to catch...?In case you think we've painted a negative picture of ...
This method will throw ArrayIndexOutOfBoundsException if you pass an index whose value is very small (negative number) or very large (larger than number of elements contained by the Vector currently). If you try to compile ListOfNumbers class, the compiler prints the error message about an ...
