Regex Matcher In Apex

The blow code is replacing the SSN number with * from a sentence.

Sample Code:

String searchText = 'This is your SSN 000-45-6789 number';
Pattern objPattern = Pattern.compile('[0-9]{3}-[0-9]{2}-[0-9]{4}');
String result = objPattern.matcher(searchText).replaceAll('***-**-****');
System.debug('searchText-' + searchText);
System.debug('result-' + result);

Lightning Web Component(LWC) Toast Messages

A component can send a toast notification that pops up to alert users of a success, error, or warning. A toast can also simply provide information. To display a toast notification in Lightning Experience or Lightning communities, import ShowToastEvent from the lightning/platformShowToastEvent module. Here is the example to show Lightning Web Component(LWC) Toast Messages.

Toast Event Properties:

Parameter Type Description
title String (Required) The title of the toast, displayed as a heading.
message String (Required) A string representing the body of the message. It can contain placeholders in the form of {0} ... {N}. The placeholders are replaced with the links on messageData.
messageData String[] or Object url and label values that replace the {index} placeholders in the message string.
variant String Changes the appearance of the notice. Toasts inherit styling from toasts in the Lightning Design System. Valid values are: info (default), success, warning, and error.
mode String Determines how persistent the toast is. Valid values are: dismissable (default), remains visible until you click the close button or 3 seconds has elapsed, whichever comes first; pester, remains visible for 3 seconds and disappears automatically. No close button is provided; sticky, remains visible until you click the close button.
