Although you don't posted how you try to print your result, I can guess you made it like this:

public static void main(String[] args) {
double l_tot_link = 12.1666;
 
DecimalFormat df = new DecimalFormat("###.##");
df.format(l_tot_link);
System.out.println(l_tot_link);
}

If you done something like that, you will have in your console the 12.1666 value indeed. You have to know that the format method don't modify the parameter.
Try something like this:

public static void main(String[] args) {
double l_tot_link = 12.1666;
 
DecimalFormat df = new DecimalFormat("###.##");
System.out.println(df.format(l_tot_link));
}
