How about:

"12345654".replaceFirst("[0-9]{4}", "****");

You could to this:

String str = "1234567";
String firstFourChars = str.substring(0, 4);
String newStr = str.replaceFirst(firstFourChars, "****");

Or to make it shorter:

str = str.replaceFirst(str.substring(0, 4), "****");

You can use the substring function. Try something like that

 String number=1234567;
 String maskNumber="****"+number.substring(4);
