public FontKey(String family,
    int style,
    int size) 
{

}

Constructs a font key.

 public boolean equals(Object obj) 
{
            if (obj instanceof FontKey) {
                FontKey font = (FontKey)obj;
                return (size == font.size) && (style == font.style) && (family == font.family);
            }
            return false;
}

Compares this object to the specifed object. The result is true if and only if the argument is not null and is a Font object with the same name, style, and point size as this font.

 public int hashCode() 
{
            int fhash = (family != null) ? family.hashCode() : 0;
            return fhash ^ style ^ size;
}

Returns a hashcode for this font.

 public  void setValue(String family,
    int style,
    int size) 
{
            this.family = (family != null) ? family.intern() : null;
            this.style = style;
            this.size = size;
