Java String is getting replaced with case sensitivity

Question

I have a string where I have to replace it with a substring. For eg, "Servicing" is the word. I have a substring as "servi". Now, i need to check if "Servicing" has "servi". If yes, then i need to replace it with "servicing". When i try to replace, it is getting displayed as "servi". But the expected output is "Servicing"Can you please help me in resolving this ? Please find the code below.

String stringValue = "Servicing";
if (stringValue != null && stringValue != "") {
    i = stringValue.toLowerCase().indexOf("servi", i+1);
    if(i>=0){
        newData = stringValue .replaceAll("(?i)"+"servi", "<mark>"+"servi"+"</mark>");
        System.out.println(newData); // Case sensitive should remain same as String. Not as substring.
        i = -1;
        }
    }

You realize that `toLowerCase` does not change the value of `stringValue`, right? — bradimus, Mar 20 '17 at 12:42
I don't understand: *"Servicing" is the word* ... *the expected output is "Servicing"*. — Steve Smith, Mar 20 '17 at 12:42

Use

String stringValue = "Servicing";
if (stringValue != null && !stringValue.isEmpty()) {
     String newData = stringValue.replaceAll("(?i)servi", "<mark>$0</mark>");
     System.out.println(newData);
}

See the Java demo

Details:

(?i) - case insensitive inline modifier
servi - a literal char sequence
$0 - a backreference to the whole match value. It makes sure you insert the servi with the matched case (no need to hardcode it inside the replacement as in the original code).

Really `stringValue != ""` ?? – Fildor Mar 20 '17 at 12:46
http://stackoverflow.com/a/14721418/982149 I tend to correct this, wherever I see it. No matter if part of the question or not. But I see why this wasn't your concern. – Fildor Mar 20 '17 at 12:49
@Fildor: Good job, I also have my own "pet peeves". – Wiktor Stribiżew Mar 20 '17 at 12:50
This works awesome for case sensitive. But i am getting the output as "Servicing". The expected output should be "Servicing" – Kutty Mar 20 '17 at 12:56
Remove `\\w*` then, I thought you wanted to wrap the *whole word* starting with `servi`. – Wiktor Stribiżew Mar 20 '17 at 12:57
