ArrayIndexOutOfBoundsException not being caught and ignored

由 北战南征 提交于 2019-12-04 10:00:29
I want to catch and ignore and ArrayIndexOutOfBoundsException error (basically it's not something I have control over, so I need my program to keep chugging along). However my try/catch pair doesn't seem to catch the exception and ignore it. Hopefully you can pick out what I am doing wrong. The exception occurs at this line content = extractor.getTextFromPage(page); Here is my code: for(int page=1;page<=noPages;page++){ try{ System.out.println(page); content = extractor.getTextFromPage(page); } } catch (ArrayIndexOutOfBoundsException e){ System.out.println("This page can't be read"); } }

Strange ArrayIndexOutOfBoundsException for Java SimpleDateFormat

由 坚强是说给别人听的谎言 提交于 2019-12-04 00:51:40
We run Java 1.4. We have this method: static SimpleDateFormat xmlFormatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"); public static Date fromXml(String xmlDateTime) { ParsePosition pp = new ParsePosition(0); return xmlFormatter.parse(xmlDateTime, pp); } Where xmlDateTime = 2013-08-22T16:03:00 for example. This has been working, but suddenly stopped! We now get this exception: java.lang.ArrayIndexOutOfBoundsException: -1 at java.text.DigitList.fitsIntoLong(DigitList.java:170) at java.text.DecimalFormat.parse(DecimalFormat.java:1064) at java.text.SimpleDateFormat.subParse(SimpleDateFormat
