    Sometimes we need to replace some characters with some other set of characters. To replace a Case-Insensitive chars from string you can use the below example:

    package com.demo;
    
    public class TestApps {
    
        /*
          *@param args
         */
        public static void main(String[] args){
    
            String s = "This is to replace Check String check with pattern.";
        String b = s.replaceAll("(?i:check)", "#@!*");
        System.out.println(b);
            }
    }
    

    output:

    This is to replace #@!* String #@!* with pattern.

    in the above example I'm replacing chars "check", it will replace both String "Check" and "check".

    Hope this will help you :)
