Programming language is a vocabulary and

set of grammatical rules for instructing a

computer to perform specific tasks.

Types of programming language

1. Procedure-oriented programming language

COBOL, FORTRAN, and C

2. Object oriented programming language

C++, Java, and PHP

Procedure-oriented programming language

In procedural programming our code is organized into small "procedures" that use and change our data. So our data move openly around the system from function to function.

Object oriented programming language

In Object oriented programming the data and related functions are bundled together into an "object". So that not even any other functions of the same program can use other data and our data will remain safe.

Concept of OOPSOOPS Features in brief

The programming in which data is logically represented in the form of a class and

physically represented in the form an object is called as object oriented

programming (OOP). OOP has the following important features.

Concept of OOPSOOPS Features in brief

Data Encapsulation : Encapsulation means wrapping up

data and member function (Method) together into a

single unit i.e. class.

Data Abstraction :

Abstraction is the process of hiding out the working

style of an object and showing only the required

information of the object in understandable manner.

Advantage of data abstraction is security.

Concept of OOPSOOPS Features in brief

Inheritance : Creating a new class from an existing

class is called as inheritance. Advantage of inheritance

is reusability of the code.

Polymorphism : Polymorphism means having more

than one form. In this different classes can have

different behaviors for the same operation.

Polymorphism can be achieved with the help of

overloading and overriding concepts.

Why do we need java ?

Trouble with C/C++ language is that they are not portable

and are not platform independent language.

Emergence of world wide web which demand portable

programs.

Portability and security necessitated the invention of JAVA.

History of JAVA

JAVA is general purpose

object oriented programming language developed by James

Gosling and colleagues at Sun Microsystems in the early 1990s

with promise to Write Once Run Anywhere and JVM make it

possible.

What is JVM ?

The heart of the Java

platform is the concept

of a "virtual machine“

JVM is a virtual machine

that provides runtime environment where JAVA program

runs.

It makes JAVA platform independent because JVM self work

as platform for all JAVA programs.

Editions of JAVA

J2SE(JAVA 2 Standard Edition) –

to develop client-side stand

alone applications or applets.

J2EE(JAVA 2 Enterprise Edition) – to develop server-side applications such as JAVA servlet and JAVA server pages.

J2ME (JAVA 2 Micro Edition) – to develop applications for mobile devices.

Advantages of Java

Simple

Object oriented

Architecture –neutral

Portable

Secure

Multithreaded.

Some features of JAVA

Automatic type checking

Automatic garbage collection

No directly accessible pointer

to memory

Multi threading

Introduction to JDBC

Java Database Connectivity (JDBC) is a Java

Application Programming Interface (API) for

executing SQL statements.

It consists of a set of classes and interfaces

written in Java.

It extends the various features of java, such as

security, platform independence, easy

understanding and usage.

The JDBC provides a standard interface for

accessing a database.

Java applications use the JDBC API to

connect with a database through a database

driver.

JDBC ARCHITECTURE

Java applications cannot communicate directly with a

database to submit the data & retrieve results of queries.

This is because a database can interpret SQL statements only

and not Java language statements.

Therefore, we need a mechanism to translate Java

statements into SQL statements and vice-versa.

The JDBC architecture provides the mechanism for this kind

of translation.
