the String, converted to lowercase.
- Attributes
Remarks
Converts all of the characters in this String to lower case using the rules of the default locale. This is equivalent to calling toLowerCase(Locale.getDefault()).
<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, "TITLE".toLowerCase() in a Turkish locale returns "t\u005Cu0131tle", where '\u005Cu0131' is the LATIN SMALL LETTER DOTLESS I character. To obtain correct results for locale insensitive strings, use toLowerCase(Locale.ROOT).

Remarks
Converts all of the characters in this String to lower case using the rules of the given Locale. Case mapping is based on the Unicode Standard version specified by the java.lang.Character Character class. Since case mappings are not always 1:1 char mappings, the resulting String may be a different length than the original String.
Examples of lowercase mappings are in the following table: <table class="plain"> <caption style="display:none">Lowercase mapping examples showing language code of locale, upper case, lower case, and description</caption> <thead> <tr> <th scope="col">Language Code of Locale</th> <th scope="col">Upper Case</th> <th scope="col">Lower Case</th> <th scope="col">Description</th> </tr> </thead> <tbody> <tr> <td>tr (Turkish)</td> <th scope="row" style="font-weight:normal; text-align:left">\u0130</th> <td>\u0069</td> <td>capital letter I with dot above -> small letter i</td> </tr> <tr> <td>tr (Turkish)</td> <th scope="row" style="font-weight:normal; text-align:left">\u0049</th> <td>\u0131</td> <td>capital letter I -> small letter dotless i </td> </tr> <tr> <td>(all)</td> <th scope="row" style="font-weight:normal; text-align:left">French Fries</th> <td>french fries</td> <td>lowercased all chars in String</td> </tr> <tr> <td>(all)</td> <th scope="row" style="font-weight:normal; text-align:left"> ΙΧΘΥΣ</th> <td>ιχθυσ</td> <td>lowercased all chars in String</td> </tr> </tbody> </table>
