You have a mistake in addPerson2 compared to:if ... && person.secondName.equals(book.get(i).lastName) && ... (sighs)secondName Comparison. lastNameYou don't need to add up on the list, you just have to check, and if you found a duplicate, fight and come out (mighty return). Adding is not necessary for every test within the cycle, but only when the entire list has been passed and it has been ascertained that there is no duplicate -- that is, after the cycle.The body of the method shall look such (short pattern): for (Person p: list) if (p.isTheSameThat(newPerson)) { System.out.println("Не катит!"); return; } list.add(newPerson); And, by the way, a match-check will be a good one.

In Excel 2016, Excel Online, Excel for Android tablets, Excel Mobile, Excel for Android phones is a function SWITCH♪ Form of use= SWITCH(<что сравниваем>, <значение1>, , <возвращаемое значение1>, <значение2>, , <возвращаемое значение2>, .......... <значениеN>, , <возвращаемое значениеN>, <значение по умолчанию> ) Minimum number of input parameters - 3, maximum value of the values checked - 126For older versions, we can write UDF on VBA or use cascades.

IDE said that there were two reasons for error:checked - The key word used to explicitly include the overcrowding test in arithmetic operations and the transformation of the whole type of data. https://msdn.microsoft.com/ru-ru/library/74b4xzyw.aspx ♪ So use it. if He can't and there will be a mistake.Ooh. Checkbox There is a characteristic. https://msdn.microsoft.com/ru-ru/library/system.windows.forms.checkbox.checked(v=vs.110).aspx ♪ I'll notice the properties are written with a capital letter. That's what we need to check. Naturally, we need to point at the beginning of the facility and then through the location of the object. You have it now if you hadn't been a key word, it doesn't matter. You should at least write. checkBox1.Checked That's the object that changes its properties, so you can cast an object that sent the event and check it out. Checked, i.e.if (((CheckBox)sender).Checked) { ...

Is that right? : String fromServer = in.readLine(); System.out.println("From server: " + fromServer); if(fromServer.equals("Correct!")){ String fromServerStar = in.readLine(); if(fromServerStar.equals("Correct!")){ String from = in.readLine(); System.out.println("From server: " + from); String THISfromServerStar = in.readLine(); System.out.println("From server: " + THISfromServerStar); } else System.out.println("From server: " + fromServerStar); }

You never have to so much invested. if - else, such a code cannot be read. switch - case It's not a very convenient option, either. I propose such a solution, create a dictionary where the number is the key and the text. Next, you create a cycle and pass through each key and compare it to the value you need, as soon as the key is bigger than that, you get the text with the key.var dictionary = [0 : "is a child", 12 : "is a teenager", 16 : "is youth", 25 : "is adult", 40 : "is mature", 55 : "is elderly", 75 : "is aged"] var age: String = "was never born" let anton = 31 var temp = 0 for (key, value) in dictionary { if anton > key && key > temp { age = value temp = key } } print("anton (age)") Call attention to the variable. var temp = 0, it is designed to keep the maximum age that has been found in the vocabulary, because the vocabulary does not guarantee you the order of the elements, different from the mass, you can't just walk through the vocabulary and find the meaning that will be more than that. anton♪ Once the cycle found an element that was more than anton, keep it important temp And we're going further in the vocabulary, looking for an element that's more than anton And more than temp♪

Design new byte() of the type byte, initiated by zero. byte - it's a structure, and therefore it's a significant type. By default, all significant types are compared in value. Since two copies are initiated with the same value, Compare0() returns True♪Design new byte[0] creates an empty mass of type byte♪ Massive is a reference type. When default, copies of reference types are equal only if their references are equal, i.e. copies indicate the same object. Since two copies of the mass are two distinct objects in memory, Compare1() returns False♪Details of relevant and reference types can be read https://ru.stackoverflow.com/a/488666/106 ♪

I'm suggesting that we don't do this search at all, but that's how we do it.File folder = new File("D://Photo_and_Video"); //было File newFile = new File(folder,f.getName()); if (newFile.exists()){ //что там уже дальше проверять надо. }

You're not a text inside. mAutoComplete You're cleaning, you're cleaning. mAutoComplete, i.e. variable with reference to it. You should try something like that. mAutoComplete.setText(null);To clean the text, inside. mAutoComplete

Statistic values remain between functional challenges, so these variables are started before the first functional challenge is performed fun()♪The last definition of the static variable is then taken. $counterwithout drawing attention to the internal logic of the function, the logic begins to work later when called. That's why you care. $counter You always start at 10.static $counter = 10;

The thing is, mAutoComplete.getText().toString() returns the empty line if nothing is in the field. You should either.String text = mAutoComplete.getText().toString(); if(text.isEmpty()) { // какой-то код } orString text = mAutoComplete.getText().toString(); if(TextUtils.isEmpty(text)) { // какой-то код } The second option is safer because it checks the value at the beginning. nullAnd then isEmpty()

It's very simple:$(".one, .two, .three").click(function () { alert("Clicked "+$(this).attr("class")); // дальше код события })<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button class="one">Click me!</button> <button class="two">Click me 2!</button> <button class="three">Click me 3!</button>

The best comparison isint

Because you don't need to compare lines with help. ==♪ .equals()♪ Read the comparison of simple and reference types. In your case, everything's right, the result. false

You can refix your own chat violin, I used to add to the beginning of the violin:if (document.documentElement.clientWidth > 580) { Or write in the TP Jivosite, they make individual sss styles for viewing and logic of conduct upon request.

I think you'll need this function:=ЕСЛИ(И(A1<408; A2 < 40); 1; ЕСЛИ(И(A1>408; A2 < 50); 1; 0))

You use the value as an index, while it's a submissive, that's it. foreach ($getAccount["groups"] as $k =>$value) { if((string)$getAccount["groups"][$k]["name"] == (string)$data){ $id_group = $getAccount["groups"][$k]["id"]; break; } } or foreach ($getAccount["groups"] as $value) { if((string) $value["name"] == (string)$data){ $id_group = $value["id"]; break; } }
