If the Total Marks >=15 then the User is PASS otherwise FAIL. Introduction to JAVA:-? Java is a programming language originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to byte code (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere". Java is currently one of the most popular programming languages in use, and is widely used from application software to web applications.?Principles? There were five primary goals in the creation of the Java language? It should be "simple, object-oriented and familiar".? It should be "robust and secure".? It should be "architecture-neutral and portable".? It should execute with "high performance".? It should be "interpreted, threaded, and dynamic".?Java is a fully Object Oriented language because object is at the outer most level of data structure in Java. No stand alone methods, constants, andVariables are there in Java. Everything in Java is object even the primitive data types can also be converted into object by using the wrapper class.Java TechnologyAs a development environment, Java technology provides you with large suits of tools:A compiler (javac)A interpreter(java)Object and MethodsJava is an object-oriented programming language, abbreviated OOP. Oops is a programming methodology that views a program as similarly consisting of objects that interacts with each other by means of action.Object oriented programming has its own specialized terminology. The objects are called, appropriately enough, objects. The actions that an object can take are called methods.A java application program is a class with a method named main, and when you run the java program the run-time system automatically invokes the method named main.There are two kinds of java programsApplets (Program that run from a web browser).Applications (Program that run on computer like other programs).FEATURES OF JAVA:-Platform IndependentThe concept of Write-once-run-anywhere (known as the Platform independent) is one of the important key feature of java language that makes java as the most powerful language. Not even a single language is idle to this feature but java is closer to this feature. The programs written on one platform can run on any platform provided the platform must have the JVM.?SimpleThere are various features that make the java as a simple language. Programs are easy to write and debug because java does not use the pointers explicitly. It is much harder to write the java programs that can crash the system but we cannot say about the other programming languages. Java provides the bug free system due to the strong memory management. It also has the automatic memory allocation and deallocation system.Object OrientedTo be an Object Oriented language, any language must follow at least the four characteristics.Inheritance?: It is the process of creating the new classes and using the behavior of the existing classes by extending them just to reuse? the existing code and adding the additional features as needed.Encapsulation:? It is the mechanism of combining the information and providing the abstraction.Polymorphism : As the name suggest one name multiple form, Polymorphism is the way of providing the different functionality by the?functions? having the same name based on the signatures of the methods.Dynamic binding? :? Sometimes we don't have the knowledge of objects about their specific types while writing our code. It is the way of providing the maximum functionality to a program about the specific type at runtime.????????As the languages like Objective C, C++ fulfills the above four characteristics yet they?are not fully object oriented languages because they?are structured as well as object oriented languages. But in case of java,? it is a fully Object Oriented language because object is at the outer most level of data structure in java. No stand alone methods, constants, and variables are there in java. Everything in java is object even the primitive data types can also be converted into object by using the wrapper class. Robust Java has the strong memory allocation and automatic garbage collection mechanism. It provides the powerful exception handling and type checking mechanism as compare to other programming languages. Compiler checks the program whether there any error and interpreter checks any run time error and makes the system secure from crash. All of the above features make the java language robust.Distributed The widely used protocols like HTTP and FTP are developed in java. Internet programmers can call functions on these protocols and can get access the files from any remote machine on the internet rather than writing codes on their local system.PortableThe feature Write-once-run-anywhere?makes the java language portable provided that the system must have interpreter for the JVM. Java also has the standard data size irrespective of operating system or the processor. These features make the java as a portable language.DynamicWhile executing the java program the user can get the required files dynamically from a local drive or from a computer thousands of miles away from the user just by connecting with the Internet.MultithreadedAs we all know several features of Java like Secure, Robust, Portable, dynamic etc; you will be more delighted to know another feature of Java which is Multithreaded. Java is also a multithreaded programming language. Multithreading means a single program having different threads executing independently at the same time. Multiple threads execute instructions according to the program code in a process or a program. Multithreading works the similar way as multiple processes run on one computer.?? Compiler/Interpreter ComboCode is compiled to byte codes that are interpreted by a Java virtual machines (JVM) .This provides portability to any machine for which a virtual machine has been written. The two steps of compilation and interpretation allow for extensive code checking and improved security.Several dangerous features of C& C++ eliminatedNo memory pointers?No preprocessorArray index limit checking SecurityNo memory pointersPrograms run inside the virtual machine sandbox. Array index limit checking Code pathologies reduced by byte code verifier - checks classes after loadingClass loader - confines objects to unique namespaces. Prevents loading a hacked "java.lang.SecurityManager" class, for example. Security manager - determines what resources a class can access such as reading and writing to the local disk.Good PerformanceInterpretation of byte codes slowed performance in early versions, but advanced virtual machines with adaptive and just-in-time compilation and other techniques now typically provide performance up to 50% to 100% the speed of C++ programs. Built-in NetworkingJava was designed with networking in mind and comes with many classes to develop sophisticated Internet communications. Features such as eliminating memory pointers and by checking array limits greatly help to remove program bugs.
