我想查看随机生成的颜色列表,并检查它们是否彼此不同。不像colour1 == colour2
中那样,但要确保生成的颜色不太相似。
我的意思是使用此代码(或类似代码)生成颜色列表:
Random randomGenerator = new Random();
ArrayList<Color> colours = new ArrayList<Color>();
while(true) {
int red = randomGenerator.nextInt(255);
int green = randomGenerator.nextInt(255);
int blue = randomGenerator.nextInt(255);
Color randomColour = new Color(red,green,blue);
if(!colours.contains(randomColour)) {
colours.add(randomColour);
}
if(colours.size() >= 100) {
break;
}
}
答案 0 :(得分:2)
我的第一个想法是这样的,它是伪随机的
Random randomGenerator = new Random();
ArrayList<Color> colours = new ArrayList<Color>();
int k1 = 0, k2=0, k3 = 0;
while(true) {
k1 = k1 +1 <= 4 ? k1 +1 : (k1+1)%4;
k2 = k2 +2 <= 4 ? k2 +2 : (k2+2)%4;
k3 = k3 +3 <= 4 ? k3 +3 : (k3+3)%4;
int red = randomGenerator.nextInt(255/4*k1);
int green = randomGenerator.nextInt(255/4*k2);
int blue = randomGenerator.nextInt(255/4*k3);
Color randomColour = new Color(red,green,blue);
System.out.println("R:" +randomColour.getRed()+"G:" +randomColour.getGreen()+"B:" +randomColour.getBlue());
if(!colours.contains(randomColour)) {
colours.add(randomColour);
}
if(colours.size() >= 100) {
break;
}
}
