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.

LWCToastMessage.html:

<template>
    <lightning-button label="Success" onclick={showSuccess}></lightning-button>&nbsp;
    <lightning-button label="Error" onclick={showError}></lightning-button>&nbsp;
    <lightning-button label="Warning" onclick={showWarning}></lightning-button>&nbsp;
    <lightning-button label="Information" onclick={showInfo}></lightning-button>&nbsp;
</template>

LWCToastMessage.js:

import { LightningElement } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
export default class LWCToastMessages extends LightningElement {

    showError() {
        const evt = new ShowToastEvent({
            title: 'Error',
            message: 'This is an error message',
            variant: 'error',
            mode: 'dismissable'
        });
        this.dispatchEvent(evt);
    }

    showSuccess(){
        const evt = new ShowToastEvent({
            title: 'Success',
            message: 'This is a success message',
            variant: 'success',
            mode: 'dismissable'
        });
        this.dispatchEvent(evt);
    }

    showWarning(){
        const evt = new ShowToastEvent({
            title: 'Warning',
            message: 'This is a warning message',
            variant: 'warning',
            mode: 'dismissable'
        });
        this.dispatchEvent(evt);
    }

    showInfo() {
        const evt = new ShowToastEvent({
            title: 'Info',
            message: 'This is an information message',
            variant: 'info',
            mode: 'dismissable'
        });
        this.dispatchEvent(evt);
