Converts all of the characters in this {@code String} to lower
case using the rules of the default locale. This is equivalent to calling
{@code toLowerCase(Locale.getDefault())}.
<p>
<b>Note:</b> This method is locale sensitive, and may produce unexpected
results if used for strings that are intended to be interpreted locale
independently.
Examples are programming language identifiers, protocol keys, and HTML
tags.
For instance, {@code "TITLE".toLowerCase()} in a Turkish locale
returns {@code "t\u005Cu0131tle"}, where '\u005Cu0131' is the
LATIN SMALL LETTER DOTLESS I character.
To obtain correct results for locale insensitive strings, use
{@code toLowerCase(Locale.ROOT)}.
@return the {@code String}, converted to lowercase.
