Basic Colors in Java

Question

Hi.
Hi. I have a method that generates random colors but now I need this method to generate basic colors, because with random colors again brings back too many colors. This is my method for random colors:
Random randCol = new Random();
                      String cores = null;
                      for(int i = 0 ; i < faixas.split(",").length ; i++ ){
                          String html = String.format("#%06X", randCol.nextInt(0xFFFFFF+1));
                          if(cores == null)
                              cores = html.replaceAll("#","") + ",";
                          else
                              cores += html.replaceAll("#","") + ",";
                      } Is there any way to change this method so that it generates only basic colors?
Thanks

How about putting all 'basic' colors in an array. Then you generate a random number in the range of the array size and return the color stored in the array at the calculated index.
Something like
    public Color randomColor()
        ArrayList<Color> colors = new ArrayList<Color>();
        colors.add(Color.yellow);
        colors.add(Color.white);
        colors.add(Color.red);
        colors.add(Color.pink);
        colors.add(Color.orange);
        colors.add(Color.magenta);
        // more to add...
        Date d = new Date();
        java.util.Random rnd = new java.util.Random(d.getTime());
        int lInt = rnd.nextInt(colors.size());
        return colors.get(lInt);
    }Timo
