Common Characteristic In Programming Language
May 12, 2014
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 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?

I have a class called "HelloController" and it extends SimpleFormController. I have the following method inside of HelloController.java:
protected Map referenceData(HttpServletRequest request) throws Exception {
Map<String,String> language = new dHashMap<String,String>();
language.put("Spanish", "Buenos Dias");
language.put("French", "Bonjour");
return language;
}
How would I create a JSP file that would accept a language as its input and return a greeting in that language? For example, if the user enters "Spanish", then the user should see "Buenos Dias." If the user enters "French", then the user should a see "Bonjour".

In my Icefaces 3 application I have a ManagedBean ancestor that defines common attributes to those they spread it. Including CSS styles to be apply at the menu as icons depending on whether they are selected or not. Classes that extend the CommonMBean class define styles. My question is what do I have to put in the language experssion styleClass to tell him that the getter to use is that of the parent class.
CommonMBean.java
package com.omb.view;
public class CommonMBean
private String menu1Css = "";
private String menu2Css = "";

In the servlet class I have:
String name = "James Bond";
Session.setAttribute("name", name);
Why is the attribute name and attribute value the same in all the books I've read. I know one is a string literal and one is an object but must it be the same?
Second thing I'm confused about... let's say I change the servlet code to
String name = "James Bond";
Session.setAttribute("hisname", name);
When I try to access it using JSP:
${sessionScope.name}
it works fine. So what is the point of the first argument in Session.setAttribute() ?

I am new at JSF and i want to do some things.
->When the user request for a file that is not exists i want to redirect to a valid url where i can inform him that the file does not exists.
->I am trying to use the properties messages for the language that the user has. I want to use it cause i want to reuse some of the message and it is easier to translate the page to other languages. How when the browser has a default page English to let user change the language to Italian for example but for all page.

Looking for some simple use cases for servlet filters other than tracking requests ? I was thinking of using a filter to filter out offensive language from entered text. Would that be a good use case ?

I have two ArrayLists and I want to compare them for common elements, and based on the result I want to update the first Arraylist to only have these elements. sort of like the opposite of RemoveAll() which removes elements in common and keep the ones that are unique. so far I thought of using for loop and .contains() in case it was fault,element not present, remove from list. but I was wondering
in what other ways, perhaps APIs i can use to do that?

I need to create an algorithm that finds the common element(s) in all arrays that has a signature of public Comparable[] findCommonElements(Object[] collection) that has an efficiency of at most O(knlogn), uses a query array, and accepts as input a collection of arrays. I am aware my time would be better spent learning how to use array lists and hash sets, but I am supposed to use concepts already covered, and these have not been.
I feel like this code should work, but it is returning null for the array of common elements. Which means it obviously is not working correctly. I am also likely going to need implementing the sort algorithm, but I wanted to get the part of finding the common elements set first.
public class CommonElements2<T extends Comparable<T>>
{
Comparable[] tempArr;
Comparable[] common;
Comparable[] queryArray;
/*
sort algorithm goes here
*/
public Comparable[] findCommonElements(Object[] collections)

I have developed a web portal using jsp and struts 2. I have approximately 10 JSP pages which looks exactly the same and have two text areas and two hidden fields. All 10 pages are exactly the same except for hidden field value. Can't i have a single common jsp page. How can i achieve it. A sample page i am attaching...
<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ page pageEncoding="UTF-8"%>
<%@ page language="java"%>
[Code]....
As this is an Assignment page so hidden field value is assignment. If the page is OBJECTIVEs then value will be OBJECTIVE.

I am using the following regex - [a-zA-Z0-9]{9,18} which means I can use alphabets and numbers with minimum length as 9 and maximum length as 18.It should not take special characters.
It takes values like ADV0098890 etc. but it is also taking ADV0098890[] which is wrong.
How can I prevent that ?

when a new object is created in Java it follows the idiom:
Object obj = new Object();
where the Object() constructor matches the object type Object.
But what if it doesn't? I understand from the Oracle Docs on creating objects and polymorphism that the constructor must be in that object's class or one of its subclasses. However, suppose we wanted to declare a new stack. My first instinct would be:
Stack s1 = new Stack();
But I assume it's valid to do it this way, too:
Object s2 = new Stack(); // Is there a difference here? What are we really saying about s2? I'm guessing s2 is simply an empty stack, but only has access to the Object class methods? I'm not sure why someone would ever do this, but I want to solidify my understanding of the Java hierarchy. Are there really any circumstances where someone would use a subclass's constructor when creating a new object?

I have two different "business objects", and they have multiple attributes in common(around 25 I believe, all of which are simply a String). Basically, these objects are used for documentation purposes on the same file.
The program can choose to update a given Document at any point in time, even if changes haven't been made to existing version. So what I'm trying to do, is check to see if these attributes differ any between the two files(the exisitng copy, and the new request). If so, I'll update...else I simply throw out the request. The workload can be rather intense at times so I don't want to bog down the system anymore then necessary.
Simply pulling down every attribute for each and comparing seems like a lot of overhead, any more efficient way to achieve these results?

I have a small problem to solve by which I would like to merge 2 sorted maps into 1.
Map A
-------
Keys, Values
1, A
2, B
3, C
4, D
5, E
Map B
-------
Keys, Values
1, 10
2, 20
3, 30
4, 40
5, 50
Final Map should look like:
Keys, Values
A, 10
B, 20
C, 30
D, 40
E, 50
The final map would have all the values from Map A as a key and the values from Map B as values in the Final Map. Is there a way to do this using Java?

I have done one program, that calculates the Least Common Multiple. The idea is to use WindowsBuilder on Ecplise in order to run it in a separate window. But when I started nothing happens. The code is:
import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.unit.Scanner;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
[Code] ....
Just wondering what could I do to make it happen. One thing came up on my mind - this is that need to connect the button with the function of the method, but still not sure will work.

I am working with Netbeans 8.0 and JSF2.2. I am trying to create a web site that has a common header, footer, and menu. The only part that would be dynamic is the content. So here goes...
1) I need a common template that has 4 parts, Header, Footer, Menu, Content
2) The header, footer and menu are to be in a separate files of which are called from the main template
3) The content will change based on the menu item changed
4) The menu has to change the content section only
I know how to do this in HTML but I am trying to set up some thing in JSF to learn more on JSF pages. All I am looking for is an example that I can follow along with having the multiple pages as well having the menu change the content (I have done a ton of internet searching but nothing really fits the bill).
This is the code I have currently.
Index (Main Template)
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
