Java split with a vertical bar as a delimiter

Today, we used the split function in Java to use the "|" As a separator, when the input bar, found an error, this problem should have been encountered long ago, but too long to forget!

Online a search, found the answer, this is because split inside there are two parameters, one is "limit", indicating the number of matching parameters, the other is the matching parameters, split is not a simple match, the input is "regular expression", so the problem is in this regular expression.

If you want to implement the "|" As a separator, you should enter "\\|" instead of "|".

So it should be: Str.split ("\\|");

Note: There is a "//|" on the internet, which is wrong.

So later found not match the input delimiter, then look at the regular expression bar!
