unchecked-conversion

PowerShell seems to perform bounds-checking after arithmetic operations and conversions. For instance, the following operations fail: [byte]$a = 255 $a++ $a = [byte]256 Is there any way to enforce overflows or the typecast without resorting to a manual calculation via modulo or C# and Add-Type? The behavior you want in PowerShell is achievable, though, it's a bit of a hack; and maybe there's a better way. If you just want cryptographic functionality though, it's worth calling out, that there's a TON of that already built-in to the BCL, and it's fully accessible from PowerShell (MD5, SHA, RSA,

In the Java snippet: SyndFeedInput fr = new SyndFeedInput(); SyndFeed sf = fr.build(new XmlReader(myInputStream)); List<SyndEntry> entries = sf.getEntries(); the last line generates the warning "The expression of type List needs unchecked conversion to conform to List<SyndEntry> " What's an appropriate way to fix this? Since getEntries returns a raw List , it could hold anything. The warning-free approach is to create a new List<SyndEntry> , then cast each element of the sf.getEntries() result to SyndEntry before adding it to your new list. Collections.checkedList does not do this checking for
