[SalesForce] apex string split

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

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

Use

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

[SalesForce] problem replacing and splitting string

Split in Apex is very similar to Java string split.

the pattern you pass to the split method is not a direct match, its a REGEX pattern. so the pipe symbol | is considered as a Regex input and it splits the string into individual characters.

You can use the below code to get thru this

newString.split('\\|')

[SalesForce] Apex can not remove multiple spaces in String

You can use normalizeSpace to remove duplicate consecutive spaces, or replaceAll:

String normalized = originalStringVar.normalizeSpace();
    -- or --
String normalized = originalStringVar.replaceAll('\\s+',' ');

Note that the double-backslash (\\) is needed to be treated as a single \ for regular expressions.

To remove all spaces, you can deleteWhitespace or replaceAll:

String nonSpaced = originalStringVar.deleteWhitespace();
    -- or --
String nonSpaced = originalStringVar.replaceAll(' ','');
