如何使用Java将hex转换为rgb？

public static int[] hexToRgb(String hex) {
    int r = Integer.parseInt(hex.substring(1, 3), 16);
    int g = Integer.parseInt(hex.substring(3, 5), 16);
    int b = Integer.parseInt(hex.substring(5, 7), 16);
    return new int[]{r, g, b};
}

public static void main(String[] args) {
    String hex = "#FF0000";
    int[] rgb = hexToRgb(hex);
    System.out.println("RGB: " + rgb[0] + ", " + rgb[1] + ", " + rgb[2]);
}

RGB: 255, 0, 0
