<p class='vspace'></p><h2>String</h2>
|
||
|
|
<h4>Description</h4>
|
||
|
|
<p>The String class, part of the core as of version 0019, allows you to use and manipulate strings of text in more complex ways than <a class='wikilink' href='String.html'>character arrays</a> do. 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.
|
||
|
|
</p>
|
||
|
|
<p class='vspace'></p><p>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.
