Difference between an ECN and an exchange?
What is the difference between an ECN and an exchange?
ECN is an Electronic Communication Network ,An electronic system that attempts to eliminate the role of a third party in the execution of orders entered by an exchange market maker or an over the counter market maker, and permits such orders to be entirely or partly executed.
An ECN connects major brokerages and individual traders so that they can trade directly between themselves without having to go through a middleman. Sometimes ECNs are also referred as dark pool.

What is the difference between a Stock and a Bond?
Stock is equity instrument while Bond is debt asset. Since equity is more risky associated with Market Risk it can provide more returns while Bond is
relatively safer instrument so it provide predefined interest called "coupon" though Bond is also associated with Counter Party Risk.

Why java string is immutable
Why java string is immutable?
This is one of the most popular interview question on String in Java which starts with discussion of What is immutable object , what are the benefits of immutable object , why do you use it and which scenarios do you use it.
It can also come once interviewee answers some preliminarily strings questions e.g. What is String pool , What is the difference between String and StringBuffer , What is the difference between StringBuffer and StringBuilder etc.
Though there could be many possible answer for this question and only designer of String class can answer this , I think below two does make sense
1)Imagine StringPool facility without making string immutable , its not possible at all because in case of string pool one string object/literal e.g. "Test" has referenced by many reference variables , so if any one of them change the value others will be automatically gets affected i.e. lets say
String A = "Test"
String B = "Test"
Now String B called "Test".toUpperCase() which change the same object into "TEST" , so A will also be "TEST" which is not desirable.
2)String has been widely used as parameter for many java classes e.g. for opening network connection you can pass hostname and port number as stirng , you can pass database URL as string for opening database connection, you can open any file by passing name of file as argument to File I/O classes.
In case if String is not immutable , this would lead serious security threat , I mean some one can access to any file for which he has authorization and then can change the file name either deliberately or accidentally and gain access of those file.
3)Since String is immutable it can safely shared between many threads ,which is very
important for multithreaded programming.
I believe there could be some more very convincing reasons also , Please post those reasons as comments and I will include those on this post.

What is Friend function or class why you need them
What is Friend function or class why you need them?
Shortly, friend class or function is a class or a function that declared friend of an other class. The idea behind friend class is to provide the access to the private and protected members or member functions of the friend class. There is a lot of controversial opinions on this topic and you should not usually use friends as it is a hole in your design. One of the examples where it's used is a momento design pattern.

Virtual Constructor is it possible? if yes how? if not y?
Virtual Constructor is it possible? if yes how? if not y?
A: There is nothing like Virtual Constructor. The Constructor can’t be virtual as the constructor is a code which is responsible for creating an instance of a class and it can’t be delegated to any other object by virtual keyword means.

Difference between Borland Silk test and Selenium test
Difference between Borland Silk test and Selenium test?
Solution: Selenium is completely free test automation tool, while Silk Test is not. Only web applications can be testing using Selenium testing suite. However, Silk Test can be used for testing client server applications. Selenium supports following web browsers: Internet Explorer, Firefox, Safari, Opera or Konqueror on Windows, Mac OS X and Linux. However, Silk Test is limited to Internet Explorer and Firefox. Silk Test uses 4Test scripting language. However, Selenium test suite has the flexibility to use many languages like Java, .Net, Perl, PHP, Python, and Ruby.

What is Selenium RC(Remote Control)?
Solution: Selenium RC allows the test automation expert to use a programming language for maximum flexibility and extensibility in developing test logic. For example, if the application under test returns a result set and the automated test program needs to run tests on each element in the result set, the iteration / loop support of programming language’s can be used to iterate through the result set, calling Selenium commands to run tests on each item. Selenium RC provides an API and library for each of its supported languages. This ability to use Selenium RC with a high level programming language to develop test cases also allows the automated testing to be integrated with the project’s automated build environment.

What are the limitations of using Selenium with Flex based UIs ?
What are the limitations of using Selenium with Flex based UIs ?
Solution: There is a relatively new open source project called FlexUISelenium located here, which allows Flex based UIs to be tested by Selenium. FlexUISelenium is an extension to the Selenium RC client driver that enables the Selenium RC client drivers to interact (and test) the Flex UI components and methods of the Flex application. FlexUISelenium works on the same lines as the Selenium Flash UI testing concept make calls to the ActionScript via JavaScript from Selenium.
Pros:
1)With FlexUISelenium the developers do not need to expose every method to be tested by using the ExernalInterface technique.
2)Just adding the SeleniumFlexAPI.swc library to the Flex application while building automatically exposes all methods to be called from external JavaScript.
Cons:

Cons:
- The FlexUISelenium project is quiet new and has some issues as reported on the project home page.
- Its not production ready yet and hence not very reliable.
- The developers have to include an external library which is otherwise not required for production builds.
- How would you test Pop-up window using Selenium ?
- Solution: First steps would be to determine whether this is an alert dialog -created using JavaScript's alert() or a bona-fide pop up window probably using open(). Since they both are treated differently its important to understand what kind of test case it is and what exactly interviewee asking.
Describe some problems that you had with Selenium tool ?
Describe some problems that you had with Selenium tool ?
Solution: The one big limitation in Selenium - Select a file in a File Input field for sake of uploading.
XPaths makes tests slow
Having Ids for elements make tests faster but the UI code might not have Ids for all elements
XPaths are brittle - ie flaky because if the UI developer changes anything like adding or removing a DIV, then the XPath becomes invalid and has to be updated in the tests.
