Multiple case insensitive strings replacement

Abhishek :

I want to replace multiple case insensitive strings from a String.

I could have used: org.apache.commons.lang.StringUtils.replaceEach(text, searchList, replacementList)

but is works for case sensitive strings.

Is there a similar method which works for case insensitive strings?

static String[] old = {"ABHISHEK","Name"};
static String[] nw = {"Abhi","nick name"};
static String s="My name is Abhishek";
System.out.println(StringUtils.replaceEach(s, old, nw));

Output:

My name is Abhishek

Expected:

My nick name is Abhi

Dang Nguyen :

You can try to use regex to archive it

Example

String str = "Dang DANG dAng dang";
//replace all dang(ignore case) with Abhiskek
String result = str.replaceAll("(?i)dang", "Abhiskek");
System.out.println("After replacement:" + "   " + result);

Result:

After replacement: Abhiskek Abhiskek Abhiskek Abhiskek

EDIT

---

String[] old = {"ABHISHEK","Name"};
String[] nw = {"Abhi","nick name"};
String s="My name is Abhishek";
//make sure old and nw have same size please
for(int i =0; i < old.length; i++) {
    s = s.replaceAll("(?i)"+old[i], nw[i]);
}
System.out.println(s);

Result:

My nick name is Abhi

Basic ideal: Regex ignore case and replaceAll()

From the comment @flown (Thank you) you need to use

str.replaceAll("(?i)" + Pattern.quote(old[i]), nw[i]);

Because regex treats some special character with a different meaning, ex: . as any single character

So using the Pattern.quote will do this.
