  List of Featuresin Java There are given many Features of JAVA. The JAVA Features given below are Simple and Easy to Understand. - Simple - Object-Oriented - Portable - Platform Independent - Secured - Robust - Architecture Neutral - Dynamic - Interpreted - High Performance - Multithreaded - Distributed 14 June 2017 https://www.youtube.com/bardlearning 2

  • Simple:- - Syntaxis based on C++ (So easier for programmers to learn it after C++). - Removed many confusing and/or rarely-used features e.g., explicit pointers, operator overloading etc. - No need to remove unreferenced objects because there is Automatic Garbage Collection in java. • Object-Oriented:- - Object-oriented programming(OOPs) is a methodology that simplify software development and maintenance by providing some rules. - Basic concepts of OOPs are:- - Object - Class - Inheritance - Polymorphism - Abstraction - Encapsulation 14 June 2017 https://www.youtube.com/bardlearning 3

  • Platform Independent:- -Java code can be run on multiple platforms. - e.g. Windows, Linux, Sun Solaris, Mac/OS etc. - Java code is compiled by the Compiler and Converted into bytecode. - This bytecode is a platform- independent code because it can be run on multiple platforms - i.e. Write Once and Run Anywhere(WORA). • Secured:- - Java is Secured because: - No Explicit Pointer - Java program run inside Virtual Machine Sandbox 14 June 2017 https://www.youtube.com/bardlearning 4 Class File Windows JVM Windows Operating System Linux JVM Linux Operating System MAC/iOS JVM MAC/iOS Operating System

  • Robust(All AbovePoints Makes JAVA Robust):- - Robust simply means Strong. - Java uses strong Memory Management. - There are Automatic Garbage Collection in JAVA. - There is Exception Handling and Type Checking Mechanism in JAVA. • Architecture-Neutral:- - There are No implementation Dependent Features - e.g. size of primitive types is fixed. - In C programming, int Data Type occupies 2 Bytes of Memory for 32-bit Architecture and 4 Bytes of Memory for 64-bit Architecture. But in java, it occupies 4 Bytes of Memory for Both 32 and 64 bit Architectures. • Portable:- - We may carry the JAVA Bytecode to Any Platform. • High-Performance:- - Java is faster than traditional interpretation since byte code is "close" to native code still somewhat slower than a compiled language (e.g., C++) 14 June 2017 https://www.youtube.com/bardlearning 5

  • Multithreaded:- - AThread is like a Separate Program, executing Concurrently. - We can write Java programs that Deal with many Tasks at once by defining Multiple Threads. - The main Advantage of Multi-Threading is that it doesn't occupy memory for each thread. - It shares a Common Memory Area. - Threads are important for Multi-Media, Web applications etc. • Distributed:- - We can create Distributed Applications in Java. - RMI(Remote Method Invocation) and EJB(Enterprise JavaBeans) are used for creating Distributed Applications. - We may access files by calling the methods from any machine on the Internet. 14 June 2017 https://www.youtube.com/bardlearning 6
