getter

问题 I'm trying to Create a class that holds a location,Including the following methods: Setters (mutators) for each of the data fields For the location name, you should use the trim() method to remove any leading or trailing blank spaces. Getters (accessors) for each of the data fields Constructor: You should have only one constructor that takes the place name, the latitude, and the longitude. You may expect that the data will be valid, although the strings may need to be trimmed. public class

问题 I recently was working with some code with a property that exposed a field that was updated/created passively, that is only when getting it and some flag indicated that the field needed updating. This is the code: static void Main(string[] args) { var someClass = new SomeClass(); Console.WriteLine(someClass.ClassString); Console.ReadKey(); } class SomeClass { private bool _dirtyFlag; private String _classString; public String ClassString { get { Console.WriteLine("dirty flag value in getter:

问题 I have created 2 timers in 2 separate classes. One timer increments int counter. and the other uses a get method and prints out the value of int counter. The problem is the second timer only prints out 0, 0, 0 etc if i use private int counter whereas if i were to use private static counter it prints out 1,2,3,4,5 etc which is what i want. But i would rather not use static because ive been told its bad practice. Here is my main class: import java.util.Timer; public class Gettest { public

问题 I am reading the following tutorial: The expression used in the h:dataTable/@value normally specifies a property name for which a getter was defined, which means that in the controller BookController class a property books is defined (optional) as well as a method named getBooks (this is mandatory). In this particular case it is just sufficient to define the getBooks method since there is no need of the books property in the controller class I have been trying to work such an idea in my

问题 I want to get device ID in at all classes level in swift which will be included as parameter every time async call made.And I really don't get clearly about Apple Access Control.So,I really need help So,How to make saving device id at start point and them accessible to all classes for async request? In app,didFinishLaunchingWithOptions,I will add the following code let say keychain is the library where i store value if keychain.get("deviceID") == nil{ keychain.set(UIDevice.currentDevice()

问题 I'm trying to make a setter method (setAvailForAssembly) that sets the assembledstocklevel but for some reason my if conditions don't seem to be making any effect. Why this is happening? Main Class public class TestAssembledPart { public static void main(String args[]) { // Constructing two Part objects (the base parts) Part part0 = new Part("p101", "Crank", 218, 12.20); Part part1 = new Part("p102", "Pedal", 320, 14.30); // Constructing AssembledPart object assembled from p101 & p102

问题 I'm trying to create a class in Java using BlueJ. My class is named Automobile. My goal is to be able to use my Constructor method to create cars with the variables: year, color, brand, number of doors, number of kilometers, if it's automatic (boolean), if it's sold (boolean), a description, and an identification number. All the variables have a set default value, a minimum and a maximum accepted value. I have to use getVariablename and setVariablename for my methods. My color and brand

问题 I'm trying to manage a variable like this: var isFinished: Bool { get { return NSUserDefaults.standardUserDefaults().boolForKey("isFinished") } set { NSUserDefaults.standardUserDefaults().setBool(newValue, forKey: "isFinished") NSUserDefaults.standardUserDefaults().synchronize() } } This works, however, I'm trying to make it more safe by using an if let when getting: var isFinished: Bool { get { if let isFinished = NSUserDefaults.standardUserDefaults().boolForKey("isFinished") as? Bool {

问题 I have a piece of hardware I write a class for which has multiple inputs. Each input (channel) has a name, so I created a list: CHANNELS = {"T0": 0, "Tend": 1, "A": 2, "B": 3, "C" : 4, "D" : 5, "E" : 6, "F" : 7, "G" : 8, "H" : 9} Now I would like to create a property to access the value of each channel: @property def readT0(self) return self._query("REQUEST STRING 0") # the request string expects a number, instead of the real name T0 @property def readTend(self) return self._query("REQUEST

问题 I have a class like this: Public Class MyClass Private _intList As New List(Of Integer) Private _avg As Decimal Public Sub Add(ByVal anInt As Integer) _intList.Add(anInt) End Sub Public Property Avg() As Decimal Get Dim _sum As Integer = 0 For Each anInt In _intList _sum += anInt Next Avg = If((_intList.Count > 0), _sum / _intList.Count, _avg) Return _avg End Get Set(ByVal value As Decimal) If _avg <> value Then _avg = value Console.WriteLine("Value changed") End If End Set End Property End
