How To Custom A Characteristic (property) Of A Variable
Jun 24, 2014
I have 4 variables: longitude, latitude, accuracy and distance. I need to store these variables in two different servers, one for private data and the other for public data, in the cloud. Before sending those data to the server, filtering is takes place as private and public variables so that the private and public data will be send to the respective urls specified with.
public class LocationTracker{
private longitude;
private latitude;
private accuracy;
private distance;
// other tasks
}
public class Filter{
[Code]...
My intention is to assign those variables the characteristic/properties, public or private, thus, I can easily identify them anywhere in the code whether they are public or private and store them to the respective urls. If the private data attempt to be send to the public url, the rejection should be made. So, How do I do that?
Which of these is not a real differentiator for programming languages:
a) Object-oriented / Process-Oriented b) Interactive / Automated c) Interpreted / Compiled d) Strongly-Typed / Weakly-Typed e) All of the above f) B and C g) B and D
Almost all support OOP, Interactive/Automated, Interpreted/Compiled but not sure about Strongly typed/Weakly typed.
I am trying to do a read/write int property called currentQuestionIndex. This property is the index of the question currently selected, and the value of the property is 0 when a DrivingTest object is first created. I dont understand how to do this. I am not sure how to get the index of the current question. i was trying to use an iterator but i dont think i was doin it right. My question class that hold all my data
package cs320Labs.servlet; public class Question { String description; String answerA; String answerB; String answerC; int correctAnswer;
Using JDK7 is there a way to get an object that has got a specific property from the collection? For instance, I might want to seek if there is an Address containg "Tim Carlton" in the ArrayList.
lst contains list of objects and one of the objects contains the property bDate(Timestamp) which has the value 28-2-1989 00:00:00.0, now I just wants to change the value into 28-2-1989 and store it back into the List as a Timestamp. how can I do that.
I am trying to find a way to make a URL that is used during a background AJAX call to log a user out more flexible. Currently, I have it as a static value, as below:
var logoutURLTest = "https://test.myorg.com/cas/logout"; ...AJAX stuff that uses the logoutURLTtest variable...
However, if that URL was to change for any reason, I would have to modify one or more JSPs if they were affected, instead of just changing it at a single point in the Spring environment context. It would be more desirable to expose the value using a property placeholder; however, the Spring documentation isn't exactly clear on whether this is possible.
The following gives the error: E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E:

The bean property is an ArrayList<String> with two elements, '100','true'
<c:choose> <c:when test="${sidocObj.samplesizedata.get(1) == 'true'}"> <img class="modified15" src="/QMSWebApp/Images/check[2].jpg"><SPAN class="scaledLimeSpan1">Sample Size has been Overriden by SQE!</SPAN><BR> </c:when> </c:choose>
I have a Die class that extends Label. It has a SimpleIntegerProperty called faceValue. In another class I have an ObservableArrayList of Die called dice and a FilteredList of all the die in dice with a faceValue of 2. The Problem is that when I update the faceValue (ie. roll()) the filteredlist doesn't update with the Die that faceValue=2. I believe the reason is that the filteredlist updates when a ListChangeListener is fired. If i add, subtract elements from dice I don't have a problem but how do I make it so that updating the faceValue on the die counts as a ListChange, or is there even a way to do that.
In the SceneBuilder properties panels (part of Inspector pane) there are nice subheaders - separated by horizontal lines with a decent gradient in the background. I've tried to investigate the SceneBuilder source code at [URL] …, but I haven't found the proper file where this subheader is defined and styled.
I'd like to use similar subheaders in my app and why to reinvent the wheel...
I generated a WebService from a WSDL using JAXWS and import the finally generated WSDL to my SOAPUI to send out the request and view the response. For some reason, I always have to set WSS TimeToLive as 1000 in the request properties, else I get an error in the response. Now, I generated a client from the WSDL. I wonder if I need to set the WSS TimeToLive here as well
I have a properties file with a set of commands and their meanings (Command = the meaning). I Populated a jtree with the keys from the properties file, now when I click a node in the jtree (key) I want the value of that selected key to go in the panel that sits in my app next to the jtree.
this is a syntax error within Jasper reports in the printwhenexpression property.I can use the following expression successfully: new Boolean ($F{off_peak_free_minutes}. trim().equals("")==false) - this basically tells Jasper Reports to ignore the column unless it has a value.
Now I'm trying to do the same thing with ZERO but I can't get the syntax right. I've tried: new Boolean($F{off_peak_free_minutes} != 0) but the ZERO comes up with a red underline implying that this is illegal.I've also tried: new Boolean($F{friends_family_minutes}!=Double.valueOf(0)) but the ZERO comes up with the red underline.
I suspect I'm just not specifying the JAVA right. I believe that the $F{friends_family_minutes} variable is a DOUBLE - it prints as 0.00 on the report.
get updated bean property in javascript function. This function I am calling from <a4j: commandbutton> this button is having actionListner, which is updatin bean property based on some User selection. When this action is completed then I am calling javascript function in oncomplete. But that javascript function is not taking updated bean value, it is always taking first value.I can't use hidden text as there are some drop downs which User will selct and then hit commandbutton which will update bean property.
I already used properties file without problems for localizing information. In that case the property file was stored as a resource in a package; and I used the Class ResourceBundle to manage the operations and the ClassLoader to access to the file.
Actually I need to use property files “To save the configuration of the application”.In this case I need also to update information stored inside the file.property, and I used the same procedure as before to manage it (ClassLoader to get data- also for writing).
I had problems in this case: that the data was never modified inside the properties file. I investigate, and now I think that the problem comes from writing in the property file that is located in the .jar file. For what I know, it is impossible to change resources putted in the .jar files.
I found a solution: to store the properties files out the jar files; and in this way all is good. But it would be more comfortable to store inside.
My question is : if a file property used to “save the configuration of the application “ have to be put out of jar, or is there another way ??
select 3 elements from the list: you'll see the log of the ChangeListener that tell you every time all items selected remove 1 element from previous selection: you will not receive the notification!!! remove the other two elements: only when the selection is empty you will see a new notification from changeListener...
In a project I'm ivolved in I have to dynamically add some components. All was going well until I had to generate data tables dynamically. I'm iterating a list of "SomeObject" and when I try to access a property of that object Glassfish tells me that object doesn't have such a property that is readable. I have getters for those properties and SomeObject implements Serializable as well. I used BalusC resources but I'm having no luck.
I want to read property file in java from command line argument,i.e. if i have some parameters which i have to use separately , i comment the parameters which i don't have to use that time , then uncomment when i have to use.
Is there and way to read the required parameters through command line arguments in java.
The term "Local variable" is related to scope. That is a local variable is one which is defined in a certain block of code, and its scope is confined inside that block of code.And a "Member variable" is simple an instance variable.
I read in a discussion forum that when local variables are declared (example code below), their name reservation takes place in memory but they are not automatically initialized to anything. On the other hand, when member variables are declared, they are automatically initialized to null by default.
Java Code: public void myFunction () { int [] myInt; // A local, member variable (because "static" keyword is not there) declared } mh_sh_highlight_all('java');
So it seems that they are comparing local variables and member variables. While I think a member variable can also be be local in a block of code, isn't it?
Is it possible to validate the input of a TextField that ist bound to a Property before both values are updated? Following is an example of my problem .....
In my model, there is a SimpleDoubleProperty discount. As you can see, there is some validation logic in the method setDiscount that might be used by other parts of the model.
public class Model { private DoubleProperty discount = new SimpleDoubleProperty(); public DoubleProperty DiscountProperty() { return discount;
[Code] ....
My Main class has a Textfield that is bound to the discount-property, a button to put the current value of the discount-property to console and a button to call the setDiscount-method ......
public class Main extends Application { @Override public void start(Stage primaryStage) { try { Model model = new Model(); BorderPane root = new BorderPane(); Scene scene = new Scene(root,100,100);
[Code] .....
By using the bidirectional Binding between the TextField and the discount-Property, the setter in the model is never called and therefore there is no validation of the input value. When calling the setter programatically with the second button, everything works as expected.
I experimented with neglecting the Binding and using ChangeListeners for both the TextField and the discount-Property but only produced infinte loops when both listeners triggered each other alternating.
I try to bind the text-property of a selected cell of a TreeView to a label. So if the user click on a cell in the treeview the label should show the cell text. Now I am quite confused about the options I got to do so. Should I use label.textProperty().bind( ... ??? ... ) The treeview.onMouseClicked()property? or something different?
