这里面包含了一百多个JAVA源文件

Some applications need to mark a range of characters in a string with an attribute, such as a color. The AttributedString 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. 
This example marks a word in a string with the attribute called color and the value red. 

    // 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("color") {
        };

    // Create the attributed string
    AttributedString astr = new AttributedString("the hot pot");
    
    // Add the COLOR attribute on the word `hot'
    astr.addAttribute(COLOR, "Red", 4, 7);
