When we create string with new() Operator, it’s created in heap and not added into string pool while String created using literal are created in String pool itself which exists in PermGen area of heap.

String s = new String("Test");

does not put the object in String pool , we need to call String.intern() method which is used to put them into String pool explicitly. its only when you create String object as String literal e.g. String s = "Test" Java automatically put that into String pool.

The differences between HTML and XHTML are:

- HTML is application of Standard Generalized Markup Language(SGML) whereas XML is application of Extensible Markup Language(XML).

- HTML is a static Web Page whereas XHTML is dynamic Web Page.

- HTML allows programmer to perform changes in the tags and use attribute minimization whereas XHTML when user need a new markup tag then user can define it in this.

- HTML is about displaying information whereas XHTML is about describing the information.

Why they ask this and what they are looking for:

This question "What areas would you like to further develop professionally?" will uncover whether you are interested and knowledgeable about your own development and as such will can be a cloaked attempt to discover your weaknesses.

A common target of the question is to discover how motivated you are to extend yourself. If you are motivated to learn, then you are probably more motivated to do the job well.

How to answer this:

First show that you are concerned and active about your own development. You can indicate how development has worked for your in the past.

You're right, continued learning and development is important and I continue to work to improve key skills.

Do answer the question, of course, but do not show gaping holes in your skill set and especially those in key areas required in the job. A good trick is to talk about developing your skills in new areas that will be of future benefit to the company.

For example : I am in programming now and love the work, but one day I would like to develop into a management role.

Hope this helps you..!

Wi-Fi technology is a technology used for transmitting a signal using the 802.11 specifications works a lot like it does with a basic Ethernet hub: They’re both two-way forms of communication, and they both use the same frequency to both transmit and receive, often referred to a half-duplex. WLANs used radio frequencies (RFs) that are radiated into the air from an antenna that creates radio waves. These waves can be absorbed, refracted, or reflected by walls, water, and metal surfaces, resulting in low signal strength. So because of this vulnerability to surrounding environmental factors, it’s pretty apparent that wire-less will never offer us the same robustness as a wired network can, but that still doesn’t mean we’re not going to use or run the wireless or Wi-Fi.
