So in the above, you want to get the 201309171500. You can do that with a regular … Read more
Just like previous question – there is no such variable number when you write acctNum = number; in public FlexibleAccount(String owner): public FlexibleAccount(String owner) { balance = 0; name=owner; Random generator = new Random(); number=generator.nextDouble(); << number is not declared this.acctNum= number; } EDIT: This is your 2nd constructor: public FlexibleAccount(double initBal, String owner, double … Read more
Here is a more efficient algorithm: For each unique number that is present in at least one of the sublists, let’s maintain a list of indices of all sublists that contain this number. This part is O(n * log n) time if we use sorting to find unique numbers or O(n) if we use a … Read more

You can achieve this via setTimeout, querySelector and css transition document.querySelector(‘.curtain’).addEventListener(‘click’, function(e) { let f = document.querySelector(‘.fadeout’) setTimeout(function() { f.classList.add(‘fade’) }, 500); setTimeout(function() { f.parentNode.removeChild(f) }, 3500); }); .fadeout { opacity: 1; transition: all 3s; background-color: #f00; color: #fff; padding: 20px; } .fade { opacity: 0 } <div class=”fadeout”>Test fade</div> <button class=”curtain”>click me</button> 12 solved … Read more
Just loop over the creation until your condition is satisfied: var forbidden = new List<Tuple<int, int>>(); forbidden.Add(new Tuple<int, int>(5, 5)); forbidden.Add(new Tuple<int, int>(7, 9)); while(true) { x = random.Next(0, 20); y = random.Next(0, 20); if(forbidden.All(t => x != t.Item1 || y != t.Item2)) break; } This way, the loop will only terminate if you have … Read more
Yes, they are hexidecimal numbers. The case of the x will not make a difference. You are correct, the methods that are public can be called from outside of the class. 2 solved What decimal value does some hexadecimal constant have in Android [closed]

You can’t use IF as a statement in a query, it can only be used in a stored procedure. To do what you want, you need two separate queries. Try this: $del_query = “DELETE FROM favoritebills WHERE userid = ‘$userid’ and billid = ‘$billid'”; $ins_query = “INSERT INTO favoritebills (userid,billid) VALUES($userid,$billid) “; $res = mysqli_query(dbcxn(‘bill’),$del_query) … Read more
