Definition:

Servlets are just a common technology for server-side Java work.

How Servlet works?

The servlet can provide the HTML to display the form and also act on the submission. Servlets can also be used to implement web services.

A servlet is simply a class which responds to a particular type of network request - most commonly an HTTP request. Basically servlets are usually used to implement web applications - but there are also various frameworks which operate on top of servlets (e.g. Struts) to give a higher-level abstraction than the "here's an HTTP request, write to this HTTP response" level which servlets provide.

What is dynamic Method Dispatch? tccicomputercoaching.com

What is Method dispatch in Java?

It is process of selecting implementation of polymorphic operation to call run time or compile time.

There are two types of Method dispatch or Binding in Java.

1) Static binding in Java

This occurs during Compile time. Static binding also known as early binding or compile-time binding.
Private, final and static methods and variables uses static binding and bonded by compiler

2) Dynamic binding in Java

This occurs during Runtime. Dynamic binding is also known as late binding or run-time binding.
Virtual methods are bonded during runtime based upon runtime object.

Method overriding is one of the ways in which Java supports Runtime Polymorphism. Dynamic method dispatch is the mechanism by which a call to an overridden method is resolved at run time, rather than compile time.

• When an overridden method is called through a super class reference, Java determines which version (super class/subclasses) of that method is to be executed based upon the type of the object being referred to at the time the call occurs. Thus, this determination is made at run time.
• A super class reference variable can refer to a subclass object. This is also known as up casting. Java uses this fact to resolve calls to overridden methods at run time.

syntax:

super class object=new subclass;

Therefore, if a super class contains a method that is overridden by a subclass, then when different types of objects are referred to through a super class reference variable, different versions of the method are executed.

Advantage:

• Dynamic binding implements Runtime Polymorphism.

• It also allow subclasses to add its specific methods subclasses to define the specific implementation of some.

Class and Object-tccicomputercoaching.com

Class and Object-tccicomputercoaching.com

Class is a user defined data type, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class. A class is like a blueprint for an    object .

The data and functions within a class are called members of the class.

For example,

class student
{
int rn;
float per;
void print()
{
cout<<"The per of rn "<<rn<<"is"<<per;
}
};

void main()
{
student s;
s.rn=10;
s.per=76.8;
s.print();
}

O/P : The per of rn 10 is 76.8

What-are-some-mind-blowing-facts-about-mathematics?tccicomputercoaching.com

We always believe math is boring, but in reality Maths is cool too!

Surprise na ? Because we don't know Some fun facts on mathematics.

Let us see some facts about Maths and sure this post make you interested to learn maths.

1. If you write out pi to two decimal places, backwards it spells “pie”.
a. For Example , 3.14 = PIE.
2. The spiral shapes of sunflowers follow a Fibonacci sequence.
3. That’s where you add the two preceding numbers in the sequence to give you the next one. So it starts 1, 1, 2, 3, 5, 8, 13, 21, etc. The Fibonacci sequence shows up in nature a fair bit.
4. A pizza that has radius “z” and height “a” has volume Pi × z × z × a.

5. Crazy multiplications

a. 11 * 11 = 121.
b. 111 × 111 = 12321.
c. 1111 * 1111= 1234321
d. 111,111 × 111,111= 123456,54321
e. 111,111,111 × 111,111,111 = 12,345,678,987,654,321.
6. Zero is the only number that can’t be represented in Roman numerals.
7. 0.999… is equal to 1
8. The Fibonacci sequence is encoded in the number 1/89
