Changing upper case string to lower case, but keep only first character to Upper case

Question

I have multiple strings in upper case:

JAMES SMITH, NAVIN HEMANT SIGNH, LALA UTRIZER

How can I transform these strings to:

James Smith, Navin Hemant Signh, Lala Utrizer in java?

Please help.

by writing code to do so, instead of asking for it. there are several ways to do this, all of which are extremely basic. write down a scenario in which it would possible (not code, just pseudo-code), so you have the logic, and after that, implement it — Stultuske, Sep 14 '16 at 10:48

Try something like this:

String values = "JAMES SMITH, NAVIN HEMANT SIGNH, LALA UTRIZER";


if (values != null && !values.isEmpty()) {
    final StringBuilder fixedCaseBuilder = new StringBuilder(values.length()+1);

    for (final String word : values.split(" ")) {
        if (!word.isEmpty()) {
            fixedCaseBuilder.append(Character.toUpperCase(word.charAt(0)));
            fixedCaseBuilder.append(word.substring(1, word.length()).toLowerCase());
        }
        fixedCaseBuilder.append(' ');
    }

    fixedCaseBuilder.setLength(fixedCaseBuilder.length()-1);
    final String result = fixedCaseBuilder.toString();
}

If you can choose what libraries to use, I would advise WordUtils from Apache Commons Utils. It has a method capitalizeFully(String s), which takes a String and capitalize the first letter of every word.
