Recently I came across the issue in java where the split command I was executing was returning an array split on every character and not the | character as I had specified.
String subStrings = myString.split( "|" );
The reason for this functionality is that the | character represent a character delimeter. To split the string only on the | character we need to escape it. However do to the nature of the split method we need to escape twice so that the final regex string is an escaped |. This means me need the following to split on the Pipe | delimeter.
String subStrings = myString.split( "\|" );
If you wanted to split on a double pipe then you would use the following:
String substrings = myString.split( "\|\|" );
