parameters

问题 Is it wrong to have a lot of parameters inside a constructor? Like 10 to 15 parameters? Because I was designing a class where a constructor will have lots of parameters, for example, a Person class. My example person class has 6 parameters in its constructor: public class Person { private String fName; private String lName; private String mInitial; private int age; private String contactNumber; private String emailAddress; public Person(String fName, String lName, String mInitial, int age,

问题 So, I tried looking up the answer to this question, and found the generally available answer is that PowerShell passes parameters by value. These generally accepted solutions all post sample code to prove their assertions, similar to the following: Function add1 ($parameter) { Write-Host " In Function: `$parameter = $parameter" Write-Host " In Function: `$parameter += 1" $parameter += 1 Write-Host " In Function: `$parameter = $parameter" } cls $a = 1 Write-Host "Before function: `$a = $a"

问题 I am building a kind of book app (Holy Quran )... user will go for a list of Surahs, each Surah contains around 5 - 50 pages. I managed navigating user from the list to first page of each Surahs.. and through getting an api request data for first page will be shown and this is the code in the showScreen const [quran, setQuran] = useState([]); const page = navigation.getParam('page'); const name = navigation.getParam('name'); let pageNumber = page; useEffect(() => { Quran(); }, []); const

问题 I just put this test method together: @Unroll def 'super start edit should be called if cell is not empty'( boolean empty ){ given: DueDateEditor editor = GroovySpy( DueDateEditor ){ isEmpty() >> empty } when: editor.startEdit() then: if( empty){ 0 * editor.callSuperStartEdit() } else { 1 * editor.callSuperStartEdit() } where: empty | _ true | _ false | _ } ... it works OK in terms of the two tests passing... but when you make it fail it's very odd: the output if the parameter empty is false

问题 I want to create a report in MS SQL Server BIDS (SSMS and Visual Studio). The user would enter a list of email addresses as a parameter. So @pEmails would be 'foo@bluh.com', 'bar@meh.org', etc. These email addresses may or may not be in a table. I can simply do: and Table.Email in (@pEmails) and that works, except I need to return the email address if it's NOT found as well. So the results would be something like: |email |found in table| |------------|--------------| |foo@bluh.com| Y | |bar

问题 I have a problem in Angular: I have three links, one of them has query params (due to using a resolver). If I click the first and the third link, the routerLinkActive is set. If I click the second link routerLinkActive is set too. But if I change the query parameter inside the component routerLinkActive gets unset. So, I need to ignore the query params. But how does it work? Can anyone help me? Here is my simple code: <div class="col-12"> <ul class="nav nav-pills nav-justified"> <li class=
