Adding an Attribute to a String</h3>
Some applications need to mark a range of characters in a string with
an attribute, such as a color. The <code>AttributedString</code> class is a
wrapper for a string that provides support for marking ranges of
characters with an attribute. An attribute consists of a name, a
value, and a contiguous range of characters on which the attribute
applies.
<P> This example marks a word in a string with the attribute called
<code>color</code> and the value <code>red</code>.
<pre>
// Declare an attribute name.
// An attribute name is an object that extends AttributedCharacterIterator.Attribute.
// Author's note: A more appropriate name would be AttributedCharacterIterator.AttributeName
static final AttributedCharacterIterator.Attribute COLOR
= new AttributedCharacterIterator.Attribute(<font color="#0066ff"><i>"color"</i></font>) {
};
</pre>
<pre>
// Create the attributed string
AttributedString astr = new AttributedString(<font color="#0066ff"><i>"the hot pot"</i></font>);
// Add the COLOR attribute on the word `hot'
astr.addAttribute(COLOR, <font color="#0066ff"><i>"Red"</i></font>, <font color="#0066ff"><i>4</i></font>, <font color="#0066ff"><i>7</i></font>);
