approximately of 400 words. Each question is followed by evaluation scheme.
1 Describe the following:
a) Multi-threading.
Answer : Multithreading in java is a process of executing multiple threads simultaneously.
Thread is basically a lightweight sub-process, a smallest unit of processing. Multiprocessing and
multithreading, both are used to achieve multitasking.
But we use multithreading than multiprocessing because threads share a common memory area.
They don't allocate
b) Significance of Java Bytecode
Answer : Java is build on WODA (Write Once Deploy Anywhere) principle. This means you don't
have to tweak a Java source code if you want to deploy it in another OS. But at the end of the day,
java programsneed a JVMto run on and JVMbeing machine language specific cannot be platform-
neutral. So, we
2 Differentiate Break and Continue statements in Java with example program.
Answer:A breakstatementwhenappliedtoa loopendsthe statement.A continue statement ends
the iterationof the currentloopand returnsthe control to the loopstatement.If the break keyword

an enclosing loop, execution skips to the end of that loop instead.
break:breaksthe current loopandmovesthe cursor to nextline afterthe loop
e.g.
3 Differentiate between packages and Interfaces.
Answer : Packages
Definition: A package is a grouping of related types providing access protection and name space
management. Note that types refers to classes, interfaces, enumerations, and annotation types.
Enumerationsandannotationtypesare special kindsof classesandinterfaces,respectively,so types
are often referred to in this lesson simply as classes and interfaces.
Creating a Package:
4 What are Applets? What are the restrictions of Applets? Describe about applet class.
Answer : What is an Applet in Java ?
An Applet is a small java program that runs in a Java enabled web browser. Java Applet is a small
piece of java code that is embedded into HTML page, which gets executed when the HTML page
loadsintothe browser.Appletsprovide powerful client-side functionality.Asappletsare loadedfrom
remote machines and executed on client-side, there are various security restrictions on applets. –
Applets Restrictions
Applets have many restrictions over the
5 Compare JDBC and ODBC
Answer : Typically, software applications are written in a specific programming language (such as
Java, C#, etc.), while databases accept queries in some other database specific language (such as
SQL). Therefore, when a software application needs to access data in a database, an interface that
can translate languagestoeachother(applicationanddatabase) isrequired.Otherwise, application
programmers need to learn and
6 Describe about Java Beans and BeanBox.
Answer : A Java Bean is a reusable software component that can be manipulated visually in an
application builder tool. The idea is that one can start with a collection of such components, and
quickly wire them together to form complex programs without actually writing any new code.
Software components must, in general, adopt standard techniques for interacting with the rest of
the world. For example, all GUI components inherit the java.awt.Component class, which means

3. that one can rely on them to have certain standard methods like paint(), setSize(), etc. Java Beans
are not actually required to inherit a
