replace
public static java.lang.String replace(java.lang.String text, java.lang.String searchString, java.lang.String replacement)The modified implementation is based on StringUtils#replace(String text, String searchString, String replacement, int max), Apache commons-lang3-3.6Replaces all occurrences of a String within another String.
