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...
Here, themultiCatch()function has two arguments. The first one is avararg, containing the types of “multiple exceptions.” A function will be executed if any exception in the definedexceptionsoccurs.This function is the second argument:thenDo(). As we can see in the code above, we wrap ...
If any other exception occurs, the second catch block handles it. Example 3: Catching Multiple Exceptions in One Block public class MultiCatchExample { public static void main(String[] args) { try { String text = null; System.out.println(text.length()); // This will throw NullPointer...

为防止和处理一个运行时错误,只需要把你所要监控的代码放进一个try块就可以了。紧跟着try块的,包括一个说明你希望捕获的错误类型的catch子句。完成这个任务很简单,下面的程序包含一个处理因为被零除而产生的ArithmeticException 异常的try块和一个catch子句。
// Demonstrate multiple catch statements. class MultiCatch { public static void main(String args[]) { try { int a = args.length; System.out.println("a = " + a); int b = 42 / a; int c[] = { 1 }; c[42] = 99; } catch(ArithmeticException e) { ...

我们将Exception的类型选择为IOException。这里UiPath的课程中没有具体给出这一异常情况的定义,我在网上查阅后得到的信息是说IOException是指在一个输入-输出执行(input-output operation)中发生的异常情况(类似Java中的Try Catch语句)。如果理解有误/补充,欢迎小伙伴及时指出。 选择完Exception的类型后,我们通过一个log ...
