 Encapsulation Encapsulation is one of the four fundamental OOP concepts. The other three are inheritance, polymorphism, and abstraction. Encapsulation in Java is a mechanism of wrapping the data (variables) and code acting on the data (methods) together as a single unit. It declares the variables of a class as private.

Fig: 1 Encapsulation in java  Inheritance Inheritance is one of the component of Object-Oriented Programming (OOPs).Inheritance permits a class to utilize the properties and strategies for another class. At the end of the day, the determined class acquires the states and practices from the base class. The determined class is likewise called subclass and the base class is otherwise called super-class. The inferred class can include its own extra factors and strategies. These extra factor and techniques separates the got class from the base class. The example of Inheritance is as follows:

The example of Polymorphism is: Fig: 2 Polymorphism Characteristics and Features of Java Java has turned out to be well known language nowadays. The credit for Java's fast ascent and wide acknowledgment goes to its plan and programming highlights. Its "Compose Once, Run Anywhere" has pulled in developers towards it. As expressed in the Java language white paper by Sun, Java is basic, protest arranged, disseminated, deciphered, vigorous, secure,

architecture neutral, convenient, superior, multithreaded, and dynamic. The features of Java are as follows:-  Java is Simple There are different features that makes the java as a basic language. Since Java is anything but difficult to learn and created by taking the best elements from different for the language most part like C and C++. It is anything but difficult to learn Java who know about protest arranged programming ideas. Java gives the mistake free advancement environment for software engineer since it gives programmed memory administration by improvement environment and dispose of pointers.  Java is Distributed: The generally utilized protocol like HTTP and FTP are produced in java. Web software engineers can call works on these protocols and can get to the records front remote machine on the web as opposed to composing codes on their nearby system. iii. Java is Secure: Java is secure since it maintains a strategic distance from express pointer and program keeps running inside virtual machine sandbox. Other than this, class loader includes security by isolating the bundle for the classes of the nearby document system from those that are foreign made from system sources. Bytecode verifier likewise checks the code parts for unlawful code that can abuse get to appropriate to objects. Subsequently these securities are given by java language. Some security can likewise be given by application engineer through SSL, JAAS, and cryptography.  Java is portable: Many kind of computer and operating system are utilized for projects by porting an interpreter for the Java Virtual Machine to any computer hardware/operating system, one is guaranteed that all code

Fig:- Example of Constructor  Class Destructor: A destructor is a special part capacity of a class that is executed at whatever point a question of its class leaves scope or at whatever point the erase expression is connected to a pointer to the protest of that class. A destructor will have identical name as the class prefixed with a tilde (~) and it can neither give back an esteem nor would it be able to take any parameters. Destructor can be extremely helpful for discharging assets before leaving the program like shutting records, discharging recollections. Following example explains the concept of destructor: Fig:- Destructor example  Variables:

A class can be characterized as a layout/diagram that describes the conduct/express that the question of its type support. Its example are as follows: Fig: Class  Object: Objects have states and practices. Case: A dog has states - shading, name, breed and additionally practices - swaying, barking, and eating. Object is an example of a class. Object can be physical or logical. Fig:- Object example Conclusion: In this task, I have explained principles, characteristics and features. Along these lines, experiencing this errand Asian Pharmaceuticals could realize what programing language has been utilized to build up their most anticipated application.

[Task 2 ] Critically evaluate the environmental flexibility of programming in Java. [2.1] Consider : Memory management, Primitives vs. objects / auto-boxing, Non- virtual methods, Single paradigm, Exception handling, Closure, Floating point arithmetic, look and feel, Performance. Introduction After the reviews and research has been done, it is found that the library administration system has not been up to the standard of the school. Along these lines, the school has employed me as a system fashioner and engineer to build offices and state of the library by building up a system that could deal with every one of the records of the library and the system would work easily even in no-lights condition. Consequently, Java programming has been chosen to build up the system. What's more, it is imperative to get comfortable with the idea of Java programming language which is done in past some portion of this report. Other than this, it is additionally vital to assess the natural adaptability of Programming in Java. The significant goal of assessing or dissecting the natural adaptability is to perceive the advantages, dangers and restrictions that Programming in Java can posture while building up the system.
