Q1. Briefly explain any two Java-based
web technologies.
Answer.
Java-Based Web
Technologies
Java Servlet
A
Servlet is a Java program module that processes and answers client requests. A
Servlet runs on the server and acts as an interface between the client and the
server. Java Servlet provides high level, component-based, platform-independent
and server-independent standards for developing web applications in Java. To appreciate
the significance of Java Servlet in developing web application, we first need
to understand the challenges that the developers were facing. When we use a web
browser to access simple, static HTML pages, the browser sends requests to a
web server. The web server uses HTTP to send back the requested web page stored
on the server. These web pages are static; they exist in a constant state.
However, with changing technologies and requirements, we now need to design a
web server to
Q2. Explain the elements of HTML document structure.
Answer. The structure of an HTML document is
made of several elements and attributes such as !DOCTYPE, html, head, and body.
The <!DOCTYPE> Tag
The
<!DOCTYPE> tag is the first element in an HTML document and it specifies
the Document Type Definition (DTD) used by the document. A DTD is a separate
file containing the formal definition of a grammar, such as the supported
elements and attributes used in the markup language. The browser
Q3. Write a short note on:
a. Special operators
b. Operator precedence and associativity
Answer. a. Special Operators
The
special operators, such as instance of and dot operators, are used to perform
certain specialized operations. The instance of operator is a binary operator
that checks whether or not an object is of a particular type (type can be a
class, interface, or an array). It is used for object reference variables only.
The syntax to use the instance of operator is as follows:
Q4. Explain dynamic polymorphism with an example of Java program.
Answer. Dynamic
Polymorphism
Polymorphism
that is exhibited at runtime is called dynamic polymorphism. This means that
when a method is called, the method call is bound to the method body at the
time of running the program, dynamically. In this case, the Java compiler does
not know which method is called at the time of compilation. Only the JVM knows
at runtime which method is to be executed. Therefore, this is also called ‘runtime
polymorphism’ or ‘dynamic binding’.
Q5. Explain the classes in Abstract Window Toolkit.
Answer: AWT is an API that helps to create
GUI-based (Windows) applications. The AWT API provides various classes stored
in the java.awt package to create GUI in the application. Using the java.awt
package, we can create and display buttons, labels, check boxes, text fields,
and other user interface components in a Windows application.
