如何在java中继续执行try catch语句 [英] How to continue execution of a try catch statement in java

问题描述

可能重复：

Java：Try-Catch-Continue？

我正在阅读来自文本文件的信息，如果读取的类型无效，我希望我的代码抛出异常。但是，在找到例外之后，我无法弄清楚如何让程序继续下去

I'm reading in information from a text file and I want my code to throw an exception if there is an invalid type being read. However, I can't figure out how to have my program continue after an exception has been found

    while(input.hasNext()) {
        try{

        type = input.next();
        name = input.next();
        year = input.nextInt();


        } catch(InputMismatchException ex)
          {
            //System.out.println("** Error: Invalid input **");
            //code to make program continue

          }

    }

推荐答案

你可以让线程离开 catch 块 - 之后的代码执行会继续。如果要在 catch 块之后跳过代码，可以在<$ c $中使用 continue 关键字c> while 循环...

You can either just let the thread leave the catch block - code execution will continue after that. If you want to skip the code after the catch block, you can use the continue keyword within a while loop...

如果要在...之后检索年份检索名称失败并发生异常，那么您将不得不在每个<$ code> try ... catch c $ c> input.next ...（）语句。在抛出异常的时候你无法重新启动执行。

If you want to retrieve a year after retrieving the name failed with an exception, then you will have to put a try ... catch around each input.next...() statement. You cannot restart execution at the point the exception has been thrown.
