Modify color java object

In Java I have declared this color object:

Color f_color = new Color(0,0,0);

Later in the code I would like to update that color variable setting, for instance, the red channel to 2. I try to do so in the following way:

f_color.r = 2;

Obviously I get an error. Is it possible to do what I am trying to ? or the only way is to create a new color object? Thank you.

Color is immutable. You'll have to create a new one:

Color newColor = new Color(oldColor.getRed()+2, oldColor.getGreen(), oldColor.getBlue());

Yes, the only way would be to create a new Color object, at least to my knowledge.

There are no setter() methods in the Color class.

However, you can store your colors in variables and then create a new color with updated values:

int r = 0;
int g = 0;
int b = 0;

Color f_color = new Color(r,g,b);

// ...

r = 2;                           // update red channel 
f_color = new Color(r,g,b);      // assign new color
