I don't know if ppl here could help finding a spot in Chennai as few are from India. Morover s I know I don't think many institutions teaching Spring and Hibernate . They may teach you servlets, JSp and EJB and anuthing out side that we may need to learn ourselves. However I found out a resource in net. Hiope it may help you.

Shan Shin's classes from http://wwwjavapassion.com . Check the JEE(advanced) classes.

Your post isn't justifying your heading as you haven't even touched anything outside the obvious. As David sadi this isn't anything you can finish of in a thread. Also since if you re gonna write a book in this thread it not going to be apt, start a blog instead.

Priyanka tell me what is the differene b/w function and method. Then may be I can explain it to you.
You won't be able to answer in Java's context as there is no function in here as Campbell Ritchie told.
From another language context both are same.

Constructors are used to create instances of your classes and at the same time initialize the variables. but it is also possible to call a constructor without any parameters. A class can have many constructors and one constructor can even call another constructor. Read the above link or any decent book on Java and you'll understand the concept clearly.

Getter and Setter methods aid in data encapsulation. Actually you can design programs without using them and javac won't complain. But in that case since your variables are declared public it would easier to tamper with from outside. By using getter and setter methods you make sure your variables are only set in a way you decide. In your code in Clock class you ned to declare a private String time.

Check sourceforge or freshmeat.

Both a re good languages. C has been the workhorse for quite some time and is still being used in many places. Java is one of the best languages available now. If you check Tiobe index Java is the first language of choice for quite some year followed by C.
C is basically procedural oriented but I belive you can write object oriented C with some outside help. Java is fully objected oriented. C now a days is mainly sed for embedded system where as Java is used in every walk of life.
Java is phenomenon. If you are planning to learn Java, you'll never regret the decision. But however if you are completely new to programming learning C first can help you a lot. Once you are good at least one language you will be able to check for yourselves the difference b/w other languages.
