Overview and Features of Java



           Java is one of the world's most essential and broadly utilized scripts, and it has held this qualification for a long time. Dissimilar to some other scripts whose impact has weared with entry of time, while Java's has developed. 
                        Starting at 2015, Java is a standout amongst the most well known programming dialects being used, especially for customer server web applications, with a revealed 9 million designers utilizing and dealing with it.  Formation of Java  Java was produced by James Ghosling, Patrick Naughton, Mike Sheridan at Sun Microsystems Inc. in 1991. It took year and a half to build up the principal working variant.  
                           The underlying name was Oak however it was renamed to Java in 1995 as OAK was an enrolled trademark of another Tech organization.  Development of Java  Java was at first propelled as Java 1.0 however not long after its underlying discharge, Java 1.1 was propelled. Java 1.1 reclassified occasion taking care of, new library components were included.  In Java 1.2 Swing and Collection system was included and suspend(), resume() and stop() techniques were belittled from Thread class.

 No significant changes were made into Java 1.3 yet the following discharge that was Java 1.4 contained a few vital changes. Watchword declare, fastened special cases and channel based I/O System was presented. 
                         Java 1.5 was called J2SE 5, it included after major new highlights : 
      Generics
      Annotations
      Autoboxing and autounboxing
      Enumerations
      For-each Loop
      Varargs
      Static Import
      Formatted I/O
          Concurrency utilities  Next significant discharge was Java SE 7 which included numerous new changes, as : 
      Now String can be utilized to control Switch proclamation. 
      Multi Catch Exception
      try-with-asset proclamation
      Binary Integer Literals 
                     Underscore in numeric literals, and so forth.  What's more, the most recent expansion to the parcel is, Java SE 8, it was discharged on March 18, 2014. A portion of the major new highlights presented in JAVA 8 are,  
      Lambda Expressions
      New Collection Package java.util.stream to give Stream API.
      Enhanced Security 
      Nashorn Javascript Engine included
      Parallel Array Sorting
              The JDBC-ODBC Bridge has been evacuated and so on.  Utilization of Java  Java is generally utilized as a part of each edge of world and of human life. Java is utilized as a part of virtual products as well as generally utilized as a part of outlining equipment controlling programming segments. There are more than 930 million JRE downloads every year and 3 billion cell phones run java.  Following are some other use of Java :
 1.   Developing Desktop Applications
 2.   Web Applications like Linkedin.com, Snapdeal.com and so on
 3.   Mobile Operating System like Android
 4.   Embedded Systems
 5.   Robotics and diversions and so on.
                         Highlights of Java  The prime explanation for making of Java was to bring versatility and security highlight into a script. Alongside these two noteworthy highlights, there were numerous different highlights that assumed an essential part in trim out the last type of this remarkable dialect. Those highlights are :
 1) Simple  Java is anything but difficult to learn and its linguistic structure is very basic, spotless and simple to understand.The confounding and uncertain ideas of C++ are either forgotten in Java or they have been re-executed in a cleaner way.  Eg : Pointers and Operator Overloading are not there in java but rather were a vital piece of C++.  2) Object Oriented  In java everything is Object which has a few information and conduct. Java can be effectively reached out as it depends on Object Model.
 3) Robust  Java attempts to dispense with blunder inclined codes by underscoring for the most part on gather time mistake checking and runtime checking. However, the fundamental regions which Java enhanced were Memory Management and misused Exceptions by presenting programmed Garbage Collector and Exception Handling.
  4) Platform Independent  Not at all like other programming dialects, for example, C, C++ and so on which are ordered into stage particular machines. Java is ensured to be compose once, run-anyplace dialect.  On aggregation Java program is gathered into bytecode. This bytecode is stage free and can be keep running on any machine, in addition to this bytecode design additionally give security. Any machine with Java Runtime Environment can run Java Programs.
  5) Secure  With regards to security, Java is dependably the principal decision. With java secure highlights it empower us to create infection free, temper free framework. Java program dependably keeps running in Java runtime condition with practically invalid cooperation with framework OS, consequently it is more secure.
 6) Multi Threading  Java multithreading highlight makes it conceivable to compose program that can do many undertakings at the same time. Advantage of multithreading is that it uses same memory and different assets to execute numerous strings in the meantime, as While writing, linguistic mistakes are checked along.
 7) Architectural Neutral  Compiler creates bytecodes, which have nothing to do with a specific PC design, subsequently a Java program is anything but difficult to intrepret on any machine. 
8) Portable  Java Byte code can be conveyed to any stage. No usage subordinate highlights. Everything identified with capacity is predefined, case: size of primitive information sorts
 9) High Performance  Java is a deciphered dialect, so it will never be as quick as a gathered dialect like C or C++. Be that as it may, Java empowers elite with the utilization of in the nick of time compiler. 
                 New Features of JAVA 8  Underneath specified are a portion of the center overhauls done as a piece of Java 8 discharge. Simply experience them rapidly, we will investigate them in points of interest later.        Enhanced Productivity by giving Optional Classes include, Lamda Expressions, Streams and so forth.
      Ease of Use
      Improved Polyglot programming.
                 A Polyglot is a program or content, written in a frame which is substantial in different programming dialects and it plays out similar operations in numerous programming dialects. So Java now backings such kind of programming procedure.     Improved Security and execution.
