methods

问题 my first question on StackOverflow. I'd like to be able to do something like: SomeClass mock = mock(SomeClass.class); String methodName = "someMethod"; OR Method method = ...someMethod... Both of these things (the mock and the method) would combine to do the following: when(mock.someMethod()).thenReturn(null); Of course, the 'null' value will be changed accordingly for my needs, but I am trying to determine two things: 1) Is it even possible to do something like this in Java? This = combining

问题 After reading this question, I've started to think about generic methods in Java 8 . Specifically, what happens with generic type parameters when methods are chained. For this question, I will use some generic methods from Guava's ImmutableMap , but my question is more general and can be applied to all chained generic methods. Consider ImmutableMap.of generic method, which has this signature: public static <K, V> ImmutableMap<K, V> of(K k1, V v1) If we use this generic method to declare a Map

问题 This question already has answers here : Closed 8 years ago . Possible Duplicate: Does Java support default parameter values? Suppose I want to make default parameter value in C++, then we can express it as below. void functionName(char *param1, int param2=2); But if I want to make this in Java, then is it possible. Currently I am doing as below public functionName(String param1) { this(param1, 2); } public functionName(String param1, int param2) { .......... } 回答1: It is not possible in Java

问题 Can I have two methods sharing the same name, but with different arguments? One would be public static and would take 2 arguments, the other one just public and takes only one argument example class product{ protected $product_id; public function __construct($product_id){ $this->product_id = $product_id; } public static function getPrice($product_id, $currency){ ... } public function getPrice($currency){ ... } } 回答1: I'm just giving you the super lazy option: function __call($name, $args) {

问题 So guys I know that have another posts like this with this name,but the other posts didn't help me find some solution for my problem. I have 1 Form and 4 Class with methods,and It's getting problem in the Class called Costs,that get's all the other 3 Class and put in him. I will post here the four classes. First Class - Alimentaçao using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace Projeto

问题 I'm trying to share variables between methods in different classes, but I don't know if I'm doing this in the correct way. Basically when I wanna use the variables on method2 I have to "transport" them throught method1 to method2 from the Class A, just take a look at the example because I don't know how to explain this properly. Is this the correct way to do it? Because sometimes I do this over an over through methods and it looks ugly. Example: public class A { int var1, var2, var3; B b =

问题 I sent a friend a workbook with a macro that includes some sorting. When he tries it he gets: Run-time error '438' Object doesn't support this property or method. He clicks Debug to see the offending code and is taken to a line or two of (fairly simple) data sorting. The text that gets highlighted is: ActiveWorkbook.Worksheets("Data Set").Sort.SortFields.Add2 Key:=Range( _ "H2:H8065"), SortOn:=x1SortOnValues, Order:=x1Descending, DataOption:= _ x1SortNormal Those 3 lines are it, part of a

问题 I'm developing "Matrix" struct and related methods for the purpose of practicing Go. I made a lot of methods but I realized that all these methods can be changed into functions I'm used to C++ and in C++, if I make a function whose parameter is a type of class, the function cannot use the class' private variable(information hiding) However, when I built a similar code using "Go", a function can access a struct's variable. So I don't get what is different between methods and functions in Go.

问题 This code will compare usernames and passwords that are stored in a text file. I think it is because of the for loop, it is probably simple but I cant see it. public int loginCheck() { //----------------------------------------------------------------- string[] users = File.ReadLines("Username_Passwords").ToArray(); //line of text file added to array //----------------------------------------------------------------- for (int i = 0; i < users.Length; i++) { string[] usernameAndPassword =
