If you're trying to get a hex representation of it like php you can use something like: data := []byte("testing") b := md5.Sum(data) //this is mostly invalid characters fmt

In short, given some: maybeIf :: ( a -> Bool ) -> a -> Maybe a maybeIf cond a = if cond a then Just a else Nothing Is there an implementation that is point-free with respect to a ? I've also been looking at a more concrete version, a -> Maybe a , and feel like there may be an

Java: Can I convert List of Object to List of String[] and vice versa?

匿名 (未验证) 提交于 2019-12-03 08:46:08
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: Is this possible without going through the list and casting the objects? I also need to convert List<Object> to List<T> (T = predefined Object) if it's possible? Edit: for clarification, I'm trying to use List<Object> as a return type of a class method that is widely used in my code. 回答1: No. This is simply not a valid conversion, because not all Object s are String[] . You could have determined this for yourself in 2 lines of code. Edit It sounds like you need to write the method more generically. Something like this: public <T> List<T>

Now getting the value could be done like this: my $keys = 'a.b.c'; my $v='something'; my $h = $hash; foreach my $k(split /\./, $keys) { $h = $h->{$k}; } print $h; # "value" But how would I set the value of key c to $v so that print Dumper $hash; would reflect the change? $h is not a ref at the end of the foreach loop, so changing that won't reflect the
