titlecase conversion.

Question

any built in methods available to convert a string into titlecase format as such??

Answer 1

there are no capitalize() or titleCase() methods in String class. You have two choices:

• using commons lang string utils.
• write (yet another) static helper method toTitleCase()

Sample implementation

public static String toTitleCase(String input) {
    StringBuilder titleCase = new StringBuilder();
    boolean nextTitleCase = true;

    for (char c : input.toCharArray()) {
        if (Character.isSpaceChar(c)) {
            nextTitleCase = true;
        } else if (nextTitleCase) {
            c = Character.toTitleCase(c);
            nextTitleCase = false;
        }

        titleCase.append(c);
    }

    return titleCase.toString();
}

Testcase

    System.out.println(toTitleCase("string"));
    System.out.println(toTitleCase("another string"));
    System.out.println(toTitleCase("YET ANOTHER STRING"));

outputs:

String
Another String
YET ANOTHER STRING
