<span>Having one password for all accounts is an easy way to remember passwords, but it will expose you to the risk of losing all of your accounts. If a person hacks one of your accounts, then they will have access to everything you own. </span>
Thank you for being the rare question where you actually provide what language you want your answer in; I approve, and encourage this.
In Java, the following will work.
I made it a bit more versatile to work with others numbers, other than 99, if you so please (if not, just hardcode the 99 in yourself).
// Example list - fill this with numbers yourself.
ArrayList<Integer> nums = new ArrayList<>();
int n = 99;
int count = (int)nums.stream().filter(i -> i == n).count();
System.out.println(n + " occurences.");
Sometimes it is hard for some people to say thank you and to rate 5 star when correct so i will you deserve it thanks for adding a correct answer! have a great day!!
A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines.
