public Color149(int redComponent,
                int greenComponent,
                int blueComponent)

This constructor creates a Color149 object with the specified RGB component values. If a component value less than 0 is specified, that component value is set to 0. If a component value greater than 255 is specified, that component's value is set to 255.

Parameters:

redComponent - The color's red component as a value 0-255

greenComponent - The color's green component as a value 0-255

blueComponent - The color's blue component as a value 0-255

Method Detail

toString

public java.lang.String toString()

This method returns a string representation of the color in the form "#RRGGBB" where RR, GG, and BB are the red, green and blue component values expressed as hexidecimal digits.

Overrides:

toString in class java.lang.Object

Returns:

The string representation of the color

equals

public boolean equals(Color149 other)

This method returns true if this color is equal to the other color and returns false if it is not equal.

Parameters:

other - The color to be compared to this color

Returns:

Whether or not the two colors are equal
