I need to call this function over a big dataset. I need it to be as efficient as possible but still be readable. Can I make it anymore efficient by using a different function for capitalize or blank check?
public static String nameFormat(String title, String firstname, String lastName) { if (StringUtils.isBlank(firstname) && StringUtils.isBlank(lastName)) { return "Unknown"; } StringBuilder fullNameSB = new StringBuilder(lastName.trim().toUpperCase()); fullNameSB.append(", "); fullNameSB.append(WordUtils.capitalizeFully(firstname.trim())); if (title != null) { fullNameSB.append(" "); // replace (mr.) with mr title = title.trim().replaceAll("\\.|\\)|\\(", ""); fullNameSB.append("("); fullNameSB.append(WordUtils.capitalize(title)); fullNameSB.append(")"); } //Remove any double spaces that might be in a multipart first or surname return fullNameSB.toString().replaceAll(" ", ""); }
