JAVA INTERNSHIP REPORT

INTRODUCTION TO JAVA:- 

Java programming language was originally developed by Sun Microsystems which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems' Java platform (Java 1.0 [J2SE]). The latest release of the Java Standard Edition is Java SE 8. With the advancement of Java and its widespread popularity, multiple configurations were built to suit various types of platforms. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications. The new J2 versions were renamed as Java SE, Java EE, and Java ME respectively. Java is guaranteed to be Write Once, Run Anywhere.

• Key Features of OOP :-

1. Classes –A class can be defined as a template/blueprint that describes the behavior/state that the object of its type supports. 
2. Objects – The instances of a class which are used in real functionality, its variables and operations. 
3. Abstraction – Specifying what to do but not how to do, a flexible feature for having a overall view of an object’s functionality. 
4. Encapsulation – Binding data and operations of data together in a single unit – A class adhere this feature.
5. Inheritance and class hierarchy – Reusability and extension of existing classes. 
6. Polymorphism – Multiple definitions for a single name - functions with same name with different functionality; saves time in investing many function names Operator and Function overloading.
7. Generic classes – Class definitions for unspecified data. They are known as container classes. They are flexible and reusable. 
8. Class libraries – Built-in language specific classes .
9. Message passing – Objects communicates through invoking methods and sending data to them. This feature of sending and receiving information. 

• Properties of java:

1. Object Oriented: In Java, everything is an Object. Java can be easily extended since it is based on the Objectmodel.
2. Platform Independent: Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being runon. 
3. Simple: Java is designed to be easy to learn. If you understand the basic concept of OOP Java, it would be easy to master. 
4. Secure: With Java's secure feature it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption. 
5. Architecture-neutral: Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many processors, with the presence of Java runtime system. 
6. Portable: Being architecture-neutral and having no implementation dependent aspects of the specification makes Java portable. Compiler in Java is written in ANSI C with a clean portability boundary, which is a POSIXsubset. 
7. Robust: Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking. 
8. Multithreaded: With Java's multithreaded feature it is possible to write programs that can perform many tasks simultaneously. This design feature allows the developers to construct interactive applications that can runsmoothly. 
9. Interpreted: Java byte code is translated on the fly to native machine instructions and is not stored anywhere. The development process is more rapid and analytical since the linking is an incremental and light-weight process. 
10. High Performance: With the use of Just-In-Time compilers, Java enables high performance. 
11. Distributed: Java is designed for the distributed environment of the internet.
