Java 随机生成16进制颜色

public static S
bb2b
tring getRandColorCode() {
String r, g, b;
Random random = new Random();
r = Integer.toHexString(random.nextInt(256)).toUpperCase();
g = Integer.toHexString(random.nextInt(256)).toUpperCase();
b = Integer.toHexString(random.nextInt(256)).toUpperCase();

r = r.length() == 1 ? "0" + r : r;
g = g.length() == 1 ? "0" + g : g;
b = b.length() == 1 ? "0" + b : b;

return "#" + r + g + b;
}
