Markdown rendering URLs with spaces

Question

Consider the following text

<code>[Collections#sort][1]</code>

[1]: http://java.sun.com/j2se/1.4.2/docs/api/java/util/Collections.html#sort(java.util.List, java.util.Comparator)

It does render correctly on preview, but incorrectly once saved. See Sorting and Re-arranging List of HashMaps for this example in real life

Answer 1

The problem is the space which breaks the URL. Try the url encoded one like:
sort(java.util.List%2C+java.util.Comparator)
instead of
sort(java.util.List, java.util.Comparator)

You can also use backticks ` for inline codes.

E.g.:

Notice that, if you want to change sort algorithm during list usage, you can instead use Collections#sort.

Answer 2

As of recently, when entering a link via the button (or Ctrl-L), the characters will automatically be escaped, so this is the safest way.
