• Is it standard behavior for this code to throw a NullPointerException?

  - by Eric

  I've had a big problem in some library code, which I've pinned down to a single statement: System.out.println((String) null); Ok, the code doesn't actually look like that, but it certainly calls println with a null argument. Doing this causes my whole applicaio to throw an unexpected NullPointerException. In general, should println throw this exception under that circumstance, or is this non-standard behavior due to a poor implementation of the out instance?

• Multilingual dates in gridview

  - by Moox

  I'm replacing a website that was previously HTML only. I put a GridView on the French and the English page and I'm getting 2 fields: A date and a currency. For the date, I need to transform it into a long date format. The English part isn't very hard, but when I get to the French page, I can't transform it into a long date format with French words (i.e.:Mardi instead of Tuesday). Is there any way to format the string with French date words instead?

• What is the difference between printf() and puts() in C?

  - by alex

  First up, I should let you know that I am learning C, so my apologies if this question seems stupid to a more advanced developer. I know you can print with printf() and puts(). I can also see that printf() allows you to embed variables inside and do some stuff like formatting. Is puts() merely a primitive version of printf(). Should it be used for every possible printf() without string interpolation? Thanks
