Sets the paint used to draw or fill shapes (or text).  If
{@code paint} is an instance of {@code Color}, this method will
also update the current color attribute (see {@link #getColor()}). If
you pass {@code null} to this method, it does nothing (in
accordance with the JDK specification).

@param paint  the paint ({@code null} is permitted but ignored).

@see #getPaint()
Sets the paint used to draw or fill shapes ( or text ) . If { @code paint } is an instance of { @code Color } this method will also update the current color attribute ( see { @link #getColor () } ) . If you pass { @code null } to this method it does nothing ( in accordance with the JDK specification ) .
