apex string split

Question

Unable to split string by multiple characters.

String myString = 'abc$$$xyz';
string[] myArray = myString.Split('$$$');
System.Debug(myArray.Size());

I get result for myArray.Size = 1 and when myArray = 'abc$$$xyz'

Please shed some light

Answer 1

String.split() expects a regular expression, not a string.

Use

myString.Split('\\$\\$\\$');
