The basic building block to modularize a program, is – the function – by separating its tasks into self-contained units. Also known as methods or procedures. A function is a program construct, having a unique name, may accept parameter(s), consists of set by step well defined instructions, and return a value or simply transfer the control [...]
Also know as looping statements, or loops. These statements execute the statement(s) repeatedly until condition remains true. Allows programmer to specify that a program shall repeat an action while some condition remains true. Types of repetition control statement includes
while statement do while statement for statement While Statement
It executes the statement(s) repeatedly until condition remains true [...]
Most programs perform arithmetic calculations to manipulate numeric data. We use arithmetic operators for such calculations. All arithmetic operators are binary operators i.e., they take two operands e.g.
number1 + number2
Here ‘+’ is the operator. Number1 and number2 are the operands. Only + and – are unary operators e.g.
x = -y
p = +x*y Summary of [...]
The best way to learn C or C++ is to start coding right away. So here is our very first program in C++.
#include is a pre-processor directive. It is not part of our program; it is an instruction to the compiler. It tells the C compiler to include the contents of a file, in this case [...]
The JavaServer Pages Standard Tag Library (JSTL) is a standard set of commonly used tag libraries. That is, JSTL encapsulates core functionality common to many JSP applications. For example, instead of iterating over lists using a scriptlet or different iteration tags from numerous vendors, JSTL defines a standard set of iteration tags. JSTL has tags for common [...]
Custom tags are user-defined JSP language elements that encapsulate recurring tasks. Custom tags are distributed in a tag library, which defines a set of related custom tags and contains the objects that implement the tags. Custom tags have a rich set of features. They can be customized via attributes passed from the calling page. They can pass variables [...]
Voice broadcasting is a mass communication technique that broadcasts telephone (recorded or live messages) calls to hundreds or thousands of call recipients at once. This technology has both commercial and community applications like Tele-marketing, Surveys, Voting, Debt control, Appointment reminder, information dissemination etc.
Voice broadcast systems manage a database of phone lists as well as digitally-recorded phone messages. There are so [...]
Web-based applications are responsible for maintaining such state, called a session, because the HTTP protocol is stateless in that every time a client sends a request, it opens a new connection and the HTTP server does not automatically maintains this conversational state of a user. To support applications that need to maintain state, Java Servlet technology [...]
JavaBeans are Java classes that can be easily reused and composed together into an application. Any Java class that follows certain design conventions can be a JavaBeans component. JavaBeans has properties of the class and public methods to get and set properties. Within a JSP page, you can create and initialize beans and get and set the [...]
