You +can concatenate Strings, append to them, search for and replace +substrings, and more. It takes more memory than a simple character +array, but it is also more useful. + + + +For reference, character arrays are referred to as strings with a +small s, and instances of the String class are referred to as +Strings with a capital S. Note that constant strings, specified in +"double quotes" are treated as char arrays, not instances of the +String class. + + + +Functions +--------- + + +- `String <http://arduino.cc/en/Reference/StringConstructor>`_\ () +- `charAt <http://arduino.cc/en/Reference/StringCharAt>`_\ () +- `compareTo <http://arduino.cc/en/Reference/StringCompareTo>`_\ () +- `concat <http://arduino.cc/en/Reference/StringConcat>`_\ () +- `endsWith <http://arduino.cc/en/Reference/StringEndsWith>`_\ () +- `equals <http://arduino.cc/en/Reference/StringEquals>`_\ () +- `equalsIgnoreCase <http://arduino.cc/en/Reference/StringEqualsIgnoreCase>`_\ () +- `getBytes <http://arduino.cc/en/Reference/StringGetBytes>`_\ () +- `indexOf <http://arduino.cc/en/Reference/StringIndexOf>`_\ () +- `lastIndexOf <http://arduino.cc/en/Reference/StringLastIndexOf>`_\ () +- `length <http://arduino.cc/en/Reference/StringLength>`_\ () +- `replace <http://arduino.cc/en/Reference/StringReplace>`_\ () +- `setCharAt <http://arduino.cc/en/Reference/StringSetCharAt>`_\ () +- `startsWith <http://arduino.cc/en/Reference/StringStartsWith>`_\ () +- `substring <http://arduino.cc/en/Reference/StringSubstring>`_\ () +- `toCharArray <http://arduino.cc/en/Reference/StringToCharArray>`_\ () +- `toLowerCase <http://arduino.cc/en/Reference/StringToLowerCase>`_\ () +- `toUpperCase <http://arduino.cc/en/Reference/StringToUpperCase>`_\ () +- `trim <http://arduino.cc/en/Reference/StringTrim>`_\ () + + + +Operators +--------- + + +- `[] (element access) <http://arduino.cc/en/Reference/StringBrackets>`_ +- `+ (concatenation) <http://arduino.cc/en/Reference/StringPlus>`_ +- `== (comparison) <http://arduino.cc/en/Reference/StringComparison>`_ + + + +Examples +-------- + + +- `StringConstructors <http://arduino.cc/en/Tutorial/StringConstructors>`_ +- `StringAdditionOperator <http://arduino.cc/en/Tutorial/StringAdditionOperator>`_ +- `StringIndexOf <http://arduino.cc/en/Tutorial/StringIndexOf>`_ +- `StringAppendOperator <http://arduino.cc/en/Tutorial/StringAppendOperator>`_ +- `StringLengthTrim <http://arduino.cc/en/Tutorial/StringLengthTrim>`_ +- `StringCaseChanges <http://arduino.cc/en/Tutorial/StringCaseChanges>`_ +- `StringReplace <http://arduino.cc/en/Tutorial/StringReplace>`_ +- `StringCharacters <http://arduino.cc/en/Tutorial/StringCharacters>`_ +- `StringStartsWithEndsWith <http://arduino.cc/en/Tutorial/StringStartsWithEndsWith>`_ +- `StringComparisonOperators <http://arduino.cc/en/Tutorial/StringComparisonOperators>`_ +- `StringSubstring <http://arduino.cc/en/Tutorial/StringSubstring>`_ + + + +See Also +-------- + + +- `string <http://arduino.cc/en/Reference/String>`_: character + arrays +- `Variable Declaration <http://arduino.cc/en/Reference/VariableDeclaration>`_ + + |
