If you don’t have a private key. You can’t decrypt. If you don’t have an encryption method and don’t have a key. You super can’t decrypt. There’s no method to figure out what encryption was used. And even if you did know unless it was md5 (I can tell by looking it isn’t) or something … Read more
How about using System.IO.Ports.SerialPort.Encoding Property? Like this: Encoding enc = new UTF8Encoding(true, true); YourPort.Encoding = enc; 6 solved SerialPort receive ?? chars, encoding is not right
With regexp: $str=”http:example.com/country/France/45″; preg_match(‘/http:example\.com\/country\/(?P<name>\w+)\/(?P<id>\d+)/’, $str, $matches); print_r($matches); // return array(“name”=>”France”, “id” => 45); 0 solved Get number from an url in PHP
As far as I can see your horizontal movement and collision detection work correctly. I enabled the vertical movement again and had to fix only a few things. Wall had to be changed to hits[0] and the y-velocity had to be set to 0 after touching a wall. def collide_with_walls(self, dir): if dir == ‘x’: … Read more
This is the simplest solution: list(zip(test2, test1)) 0 solved Python 3 – Printing the result of 2 lists [duplicate]
this is previous code on my custom adapter: @Override public Object getItem(int position) { // TODO Auto-generated method stub return (position); } and this is solved code in my custom adapter: @Override public Object getItem(int position) { // TODO Auto-generated method stub return data.get(position); } in which datais defined as ArrayList<HashMap<String, String>> data; solved Integer … Read more
The SQL standard defines multiple ways of phrasing subqueries. One of them is called “table expression” (aka “inline view”). The case you are talking about is a simple table expressions in the form: SELECT * FROM (<subquery>) <alias> WHERE <condition> In your case const is the alias. solved Where in the MySQL doc could I … Read more
Maybe what you actually want is to use a Predicate? Predicate<Integer> crazyFunction = x -> false; for (Integer thisInteger : listOfIntegers) { crazyFunction = crazyFunction.or(Predicate.isEqual(thisInteger)); } // Is a given integer one of our integers? boolean isGoodInteger = crazyFunction.apply(42); 2 solved How can I change one function value in a boolean-valued java Function?
The potential effects of a function include: Returning a value. Modifying an object, including either objects the function can access through pointers or objects with external linkage. Accessing a volatile object, as above.1 Modifying a file (a stream). So, if a function does not return a value, it can still modify an object, as in: … Read more
Why int[] aa={’12’,’2′}; is invalid and int[] aa={‘1′,’2’}; is valid? error showing is Invalid character constant [closed] solved Why int[] aa={’12’,’2′}; is invalid and int[] aa={‘1′,’2’}; is valid? error showing is Invalid character constant [closed]
string.replace won’t work, since it does not affect the original value. >>> test = “hallo” >>> test.replace(“a”, ” “) ‘h llo’ >>> test ‘hallo’ Instead you need to access the list via the indexes: for row in ArrayMulti: for index in range(len(row)): row[index] = “a” If you provide a more precise question and add the … Read more
You can get the gaps by looking at the previous row. If your table is not too large: select (t.prev_id + 1) as first_missing, (t.id – 1) as last_missing, (t.id – t.prev_id – 1) as cnt from (select t.*, (select max(t2.id) from t t2 where t2.id < t.id ) as prev_id from t ) t … Read more
Just use comparator, an example of sorting by firstName then by lastName list.forEach(l -> l.sort(Comparator.comparing(CsvEntity::getFirstName) .thenComparing(CsvEntity::getLastName))); Of course you have to have getters for your fields to use method reference solved how sort in java8 list of lists of object by multiple properties [duplicate]
Your calculation is effectively canceling: 3 + 3 * -1 = -6 -6 + 3 * -1 = 3 You can do it easier by using a simple if/else: for (i = 0; i < 2500; i++) { if (i % 2 == 0) { System.out.println(3 * i); } else { System.out.println(-3 * i); } … Read more
If you set the table view’s separator style to “none” and place any subviews of your cell away from the edges of the cell, it will appear as if there is space between the cells. If you want a border around your content (but not the actual edge of the cell to maintain the illusion … Read more
