getter-setter

问题 I'm continuing my studies for uni with C++ and I'm running into some serious comprehension issues concerning pointers, const arguments and all the very basics of class implementations (which are so easy in Java compared to C++) I usually work with Java, so C++ is very new to me. This is my simple header for a class "Person": #ifndef Person_h #define Person_h class Person { private: char* name; char* adress; char* phone; public: Person(); Person(char const *name, char const *adress, char const

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 having some trouble wrapping my head around this one. Im returning a bunch of xml from an API call (which i have no control over).The data looks like this but with many more entries. `<time>10:00:00</time> <go>true</go> <time>10:30:00</time> <go>false</go> ` I can deserialize it fine into a list two lists of strings List<string> time and list<string> go However i really need that time to be deserialized into a datetime object. Right now i have the following working but only for a single

问题 Trying to print out age and name of an Object using "get" method. However, my get method return type is string: public String displayProfile() { System.out.print(getName() + getAge()); Hence the error: This method must return a result of type String Here is my main method: if user enters '2' from the "menu" where (2 == profile) the program should display user's name and age . Side note: To select "friends" from menu, user will enter '3' (3 = friends). public static void main(String[] args) {

问题 I've tried to add the users and authentication with OAuth. I followed by tutorial: Video Here is his source code: https://github.com/arocketman/Spring-oauth2-jpa-example I've done exactly like him but my Intellij showed me some issuses. I had to change my pom.xml from <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-oauth2</artifactId> </dependency> to <dependency> <groupId>org.springframework.security.oauth.boot</groupId> <artifactId>spring-security

问题 EDIT: After being recommended to work with headers, I asked a similar question here. I'm trying to develop a Chrome extension that analyzes cookies being set/retrieved by websites and, if a cookie doesn't meet certain requirements, stops it from being set/retrieved. I figured I would have to override the cookie setter and getter. I have found similar questions: Cookie Law, Cookie setter & getter Safely overriding document.cookie in Google Chrome extension Defining a getter for document.cookie

问题 I've named the class variable with camel casing .This is the class, which seems to be the culprit. import javax.persistence.Temporal; import javax.persistence.TemporalType; import java.sql.Date; public class GameBoard { @Temporal(TemporalType.DATE) private Date lastMoveDate; /** * @return the lastMoveDate */ public Date getLastMoveDate() { return lastMoveDate; } /** * @param lastMoveDate the lastMoveDate to set */ public void setLastMoveDate(Date lastMoveDate) { this.lastMoveDate =

问题 I have three tables in MySQL database. category (excluded from this question) sub_category product The relationship between these tables is intuitive - one-to-many in the order in which they appear. I'm iterating through a list of SubCategory , List<SubCategory> using <p:dataGrid> as follows. <p:dataGrid var="row" value="#{featuredProductManagedBean}" rows="4" first="0" columns="1" rowIndexVar="rowIndex" paginator="true" paginatorAlwaysVisible="false" pageLinks="10" lazy="true"

问题 Is there any point in repeating this pattern for every property in JavaScript? class Thing { get myProp() { return this._myProp; } set myProp(value) { this._myProp = value; } } I understand that getters/setters can be useful if you're doing additional work in the methods, but recreating the basic functionality here seems like needless repetition. If I instantiate, I can still manipulate the backing property ( ._myProp ) directly, so I feel like I could just as easily leave these out and

问题 i was looking into properties and could not understand the use of getter. Code : class A: def __init__(self,p): self._p = p @property def p(self): return self._p @p.setter def p(self, value): self._p = value @p.getter def p(self): return self._p so,i did the following obj = A(10) print(obj.p) i got the following output: 10 So, i thought, @p.getter is called and the value of _q is returned. But, i tried without @p.getter as below class A: def __init__(self,p): self._p = p @property def p(self)
