java - Boolean return statement (To make it not print true/false) -

-

My program runs and compiles, however, I did not get the desired output. It produces all the necessary information, but it also prints some things which I would not like to print very true / false statements along with patrons, authors and books: 

  / * The right (current print statement) is true. True Name: Ken Lambert Title: Cider House Rule Author: John Irving Title: Perfect Hurricane Author: Sebastian Juger Title: The Illusion Author: Homer Title: Hamlet Author: William Shakespeare True Wrong Name: Ken Lambert Title: Perfect Storm Author: Sebastian Juger Title: Iliad Author: Homer Title: Hamlet Author: William Shakespeare (Current Print Statement) Name: Ken Lambert (Desired Print Statement) Title: Cider House Rule Writer: John Irving Title: Perfect Storm Author: Sebastian Juger Title: Iliad Author: Homer Title: Hamlet Author: William Shakespeare's Name: Ken Lambert Title: Perfect Storm Writer: Sebastian Juger Title: The Illusion Author: Homer Title: Hamlet Author: William Shakespeare * / Public Class Book {Private String Writer, Title; Public book (string t, string a) {author = a; Title = t; } Public string getAuthor () {return author; } Public string getTitle () {return title; } Public string toasting () {return "title:" + title + "\ n" + "Author:" + Author; }} Public Class Library Lists {Public Stable Zero Main (String [] Args) {Protector P = New Guardian ("Ken Lambert"); Book B1 = New Book ("Cedar House Rule", "John Irving"); Book B2 = New Book ("Perfect Storm", "Sebastian Junger"); Book B3 = New Book ("Iliad", "Homer"); Book B4 = New Book ("Hamlet", "William Shakespeare"); Println (p.borrowBook ​​(B1)); Println (p.borrowBook ​​(B2)); Println (p.borrowBook ​​(b3)); Println (p.borrowBook ​​(B4)); Println (P); System.out.println (p.returnbook ("Cedar House Rules")); System.out.println (p.hasBook ("Cedar House Rules")); System.out.println (p.hasBook ("Perfect Storm")); Println (P); }} Patron of the public class {Book B1, B2, B3, B4; The name of the private string; Public Protector (string nm) {name = nm; B1 = Faucet; B2 = Faucet; B3 = Faucet; B4 = null; } Public string getName (string nm) {if (name.equals (null) System.out.println ("You must give your name!"); Other name = nm; Name of return; } Public Boolean Borrowing Book (Book Book) {Boolean test = False; If (b1 == empty) {b1 = book; Test = true; } And if (b2 == empty) {b2 = book; Test = true; } And if (b3 == empty) {b3 = book; Test = true; } And if (B4 == empty) {b4 = book; Test = true; } Else {test = false; } Return exam; } Public Boolean hasBook (string title) {if (b1! = Null) if (b1.getTitle (.) Equals (title)) {back true; } And if (b2! = Null) if (b 2.getTitle (.) Equals (title)) {back true; } And if (b3! = Null) if (b 3.getTitle (.) Equals (title)) {return true; } And if (B4! = Null) if (b 4.getTitle (.) Equals (title)) {return true; }      return false; } Public Boolean Returnbook (String B) {if (b1.getTitle (). Equal (B)) {B1 = Faucet; Back true; } And if (b2.getTitle (.) Equals (b)) {b2 = zero; Back true; } And if (b 3.getTitle (.) Equals (b)) {b3 = null; Back true; } And if (b4.getTitle (.) Equals (b)) {b 4 = null; Back true; } Other {return false; }} Public string toString () {string str = "name:" + name; If (b1! = Null) str = str + "\ n" + b1; If (b2! = Null) str = str + "\ n" + b2; If (b3! = Null) str = str + "\ n" + b3; If (b4! = Null) str = str + "\ n" + b4; Return str; }} // class

method public boolean credit book (book manual) gives a boolean as you print the return of the method, it prints ... boolean! 

  System.out.println (p.borrowBook ​​(b1)); Println (p.borrowBook ​​(B2)); Println (p.borrowBook ​​(b3)); Println (p.borrowBook ​​(B4));

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
