ArrayIndexOutOfBoundsException will not be caught and ignored

I want to catch and ignore the ArrayIndexOutOfBoundsException error (basically this is not what I have control, so I need my program to continue moving).

However, my try / catch pair does not seem to throw an exception and ignore it. I hope you can choose what I am doing wrong.

An exception occurs on 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");
    }    
}

- itext , (CMapAwareDocumentFont.decodeSingleCID), :

 private String decodeSingleCID(byte[] bytes, int offset, int len){
        if (toUnicodeCmap != null){
            if (offset + len > bytes.length)
                throw new ArrayIndexOutOfBoundsException("Invalid index: " + offset + len);
            return toUnicodeCmap.lookup(bytes, offset, len);
        }

        if (len == 1){
            return new String(cidbyte2uni, 0xff & bytes[offset], 1);
        }

        throw new Error("Multi-byte glyphs not implemented yet");
    }

An exception to ArrayIndexOutOfBoundsException is standard Java. I see no reason why your original try-catch does not work.

Perhaps you should post the whole class? Also, which version of itext are you using?

Wait a second! You are missing some braces there :) Your expression about leaving outside of your statement! You have the following:

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");
    }    
}

It should be:

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");
    } 
} //end for loop  

}//This closes your method or whatever is enclosing the for loop
