ASSIGNMENT

DRIVE	FALL 2016
PROGRAM	Master of Science in Information Technology (MSc. IT)
SEMESTER	1
SUBJECT CODE & NAME	MIT108 - OBJECT ORIENTED PROGRAMMING
BK ID	B1477
CREDITS	4
MARKS	30

Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme.

Question. 1. Write a short note on Java Buzz words.

Answer: Following are the features or buzzwords of Java language which made it popular:

Simple:

·       Java easy to learn

·       It is easy to write programs using Java

·       Expressiveness is more in Java.

·       Most of the complex or confusing features in C++ are removed in Java like pointers etc..

Question. 2. Differentiate Break and Continue statements in Java with example program.

Answer: break and continue in Java are two essential keyword beginners needs to familiar while using loops ( for loop, while loop and do while loop). break statement in java is used to break the loop and transfers control to the line immediate outside of loop while continue is used to escape current execution and transfers control back to start of the loop. Both break and continue allows programmer to create sophisticated algorithm and

Question. 3. Differentiate between packages and Interfaces.

Answer: There is a huge difference between packages and interfaces.  A package is a scoping mechanism for classes within a group.  So that the names used for classes in one package do not conflict with the names (even if they are the same) of classes and public methods in another package.

Interfaces have nothing to do with scoping... they have to do with having behaviors cross a set of classes outside of an inheritance chain.  Of course, behaviors are shared via inheritance from parent class to child class - but what do you do if you want to share

Question. 4. What are Applets? What are the restrictions of Applets? Describe about applet class.

Answer: A Java applet is a small application which is written in Java or another programming language that compiles to Java bytecode and delivered to users in the form of that bytecode. The user launches the Java applet from a web page, and the applet is then executed within a Java Virtual Machine (JVM) in a process separate from the web browser itself. A Java applet can appear in a frame of the web page, a new application window, Sun's AppletViewer, or a stand-alone tool for testing applets. Java applets were introduced in the first

Question. 5. Compare JDBC and ODBC.

Answer: ODBC is an open interface which can be used by any application to communicate with any database system, while JDBC is an interface that can be used by Java applications to access databases. Therefore, unlike JDBC, ODBC is language independent. But by using JDBC-to-ODBC bridge Java applications can also talk to any ODBC compliant database.

·       Multithread: JDBC is multi-threaded - ODBC is not multi-threaded (at least not thread safe)

·       Flexibility: ODBC is a windows-specific technology - JDBC is specific to Java, and is therefore supported on whatever OS supports Java
