Introduction of java programming

Java technology is a composition of the platform and programming language. This method encourages the state of art programs to support the utilities, games, and business-related services. In 2012, Java was the most wanted and important programming language for more than 10 million clients, particularly customer server-based applications. Java has turned out to be the most important part of operations and performance for some websites and applications. Without the installation of Java, the system might not have the capacity to operate or run the software or programs, since it gives speed and proficiency with security.

This article will give you guidance on Java. If you want to learn more about Java programming, you should go through this blog. This blog consists of features, history, and much more.

  • Java is a broadly useful, object-oriented programming language that is intended to create software for electronic gadgets, for example, VCR, TV, toaster, and so on.
  •  Java is a neutral language platform, which implies that it isn’t tied to a specific operating system or hardware. It ensures clients compose once and run at anyplace.
  • All operating systems like Windows, Linux, Mac, support Java programming language.

History of Java programming

Mike Sheridan, James Gosling, and Patrick Naughton started the project of Java language in June 1991. Java was initially made for interactive TV, but at the time digital satellite TV was extremely advanced for the industry of television. The language was at first called oak after an oak tree which was outside the office of Gosling. Later, the project was renamed Green, and lastly, Java’s name was changed to Java. Gosling designed Java with a style syntax of C/C ++ structure, which will familiarize framework and application programmers.

In the year of 1996, Sun Microsystem released public implementation as a Java version 1.0. For the improvement of the Java language, the group included Patrick Knotton, who founded some real disadvantages as far as portability and reliability in existing languages like C and C ++. He designed the new language Java on C and C ++, while a few features were not there. It has made Java genuinely powerful, portable, and simple.

History of java in chronological order

  • 1990: A group of Sun Microsystems Programmers chose to build up a unique software to control electronic gadgets. James Gosling was leading the group.
  • 1991: The group examined different languages at that time, i.e., C, and C ++, and announced the new language “oak.”
  • 1992: In the Sun microsystem, a team known as Green Project, demonstrated its new language application, that can control a variety of home appliances using a hand tool with a small touchscreen.
  • 1993: The World Wide Web went live on the web and transformed the content-based web into a graphical, enriched condition. The Green Project group pretends the possibility of developing web applications (small programs) that can keep running on a wide range of computers that connected to the Internet.
  • 1994: In this year, the team built up an internet browser named “Hotjava” to discover and run applet programs on the web. This became very common among the users of the internet.
  • 1995: Because of some legal issues, Oak’s name changed to Java.
  • 1996: Sun Microsystem released Java Development Kit 1.0.

Principles of java proramming

While making Java Language, there are five main objectives:

  1. Familiar, object-oriented and simple.
  2. Should be secure and robust.
  3. It should be portable and architectural-neutral.
  4. It should execute with very high performance.
  5. Dynamic, threaded and interpreted.


The principal objective was to structure a language that would offer answers to the issues faced by current programming. Dependable, distributed, and portable were few objectives of the language. It should also be compact, simple, and interactive. This is an essential part, in the case that you are writing a java assignment help.

Interpreted and Compiled

The Java language mix both methodologies, hence making Java a two-step framework.

  1. In the first step, java language used to change the source code to the instructions of byte codes, these are not machine instructions.
  2. Second, the interpreter of Java produces machine codes that can execute directly by a machine running Java programs.

Portable and Independent

Java is any time, anywhere programming language, which means that it can be moved from any system, anytime and anywhere. In case of any change on hardware, operating system, processor or system resource will not affect Java Programs.

Java programming guarantees portability in two different ways. Most importantly, the Java compiler produces byte code instruction that can be initialized to any machine, and furthermore, the size of the primitive information types is machine-independent. However, we can help you with every programming assignment.


Nearly everything in the language of Java is an object, which makes it a genuine object-oriented language. All the information and programming code live in classes and objects. Java accompanies a complete set that is organized in bundles, which can be utilized in program legacy.

Secure and Robust

  • Java gives numerous safety efforts to ensure reliable code. It has stern run-time, check for data types.
  • The Java framework confirms all memory access, and, in this way, it ensures that no infections transmit to the applet.

Performance and Scalability

J2SE 5.0 improves startup time and decreases the memory utilized in the Java 2 runtime environment.

Ease of Development

Java 2 Standard Edition version 5.0 used to support features like Enhanced for loop, Generics, Unboxing or Autoboxing, Typesafe enums, Annotation, and Static import. These features of Java make it simple for the programmers of Java by transferring the responsibility of making the code which is reusable on the compiler, and bug-free codes.

Maximum Performance

Java programming execution is exceptionally amazing, given the way that it is an interpreted language, basically due to bytecodes. Java intends to decrease overheads.

Interactive and Multithreaded

Multithread refer to dealing with various task or projects at the same time. Java language supports multithreaded programs, which implies that we don’t need to hang tight for one task to begin another. This component of Java enormously improves the interactive execution of graphical applications.


Java programming gives the capacity to share both programs and data. One can easily access Java applications and open remote objects on any nearby machine on the Internet.

Execution System

Java Bytecode and Java JVM

Portability is one of the design objectives of Java, which implies that the programs composed for the Java platform should keep running on any combination of operating system and hardware with adequate run time support. It is acquired by combining the Java language code for an intermediate presentation known as Java bytecode instead of the architecture-specific machine code.

The instructions of Java bytecodes are equivalent to machine codes; however, they expect to be performed by a virtual machine (VM), which is specifically composed for host equipment. End users usually utilize the Java Runtime Environment (JRE) introduced without anyone else machine in an internet browser for Java applets or for independent Java applications.

The common way to access host-specific features like threading, graphics and networking are provided by Standard Libraries.

Portal is made easy to navigate and simple with the help of universal bytecode. However, the programs interpreted by the overhead of the interpretation of bytecode in machine instructions almost always run more slowly than the native execution. JIT or Just-In-Time compiles the bytecodes to machine codes at the time when run-time was introduced from an initial stage.

An applet resembles any application, yet it doesn’t run stand-alone. An applet must pursue a set of conventions that enable it to keep running inside a Java-enabled browser. Innovation is still developing, and today, most Java applets are user interaction or basic animations. Future is brilliant, promising full applications on the Internet; Imagine utilizing Microsoft Office from your TV.

In the present, however, individuals who have experienced an applet might be confused. An unpremeditated user is probably not going to be impacted by looking over lessons, or basic animation, particularly in a case that they need to pay for download time over them.


A few platforms provide direct support for hardware for Java; Java bytecodes can run by microcontrollers in hardware rather than a software JVM, and some ARM-based processors can support hardware to execute Java bytecodes via their Jazelle option, although the ARM’s current Support in implementation has mostly dropped.

Automatic memory management

Java uses an automatic garbage collector for managing the memory in the lifecycle of the object. At the point when objects are made, the developer decides, and Java runtime recovers the memory when the objects are not being used. Once there is no reference to an item, at that point, the unreachable memory becomes eligible for getting freed by the garbage collector automatically. Something like a memory leak can happen regardless of whether the software engineer’s code holds. If the techniques for a non-existent object are called, at that point ” null pointer exception ” is thrown.

Java vs C++

  • The distinction between programming languages C ++ and Java can be followed to their inheritance since they have diverse plan objectives.
  • C ++ was intended for application and system programming (for example infrastructure programming), which expands the procedural programming language C, which was intended for effective execution.
  • For C, C ++ incorporates object-oriented programming, special case taking care of, lifetime-based resource management (RAII), templates metaprogramming, generic programming, and C ++ standard libraries, which incorporate calculations and generic containers (Standard Template Library/STL).
  • Java is class-based, and object-situated programming language that intends to decrease reliance. It is subject to a Java Virtual Machine which is protected and very convenient.
  • Java has been bundled with a broad library which is intended to give a total theoretical of the inherent platform.
  • Java is a statically composed item arranged language, which utilizes a syntax structure like (however incompatible) like C ++. It incorporates a documentation framework called Javadoc.
  • C ++ supports the statement of Goto, which can cause spaghetti code programming.
  • Except for the Goto statement, both Java and C ++ have essentially a similar control stream structure. To execute organized control stream It plans, and relies upon the brakes, and keeps on giving the statement to behave like Goto.
  • A few analysts demonstrate that these mark stream control explanations break the single call attention to the property of organized programming.


Java has essential points of interest as a business language, and as an educating language. This enables students to learn object-oriented programming without featuring the complex nature of C ++. It generally gives stricter compile-time error checking related to Pascal. This enables the instructor to explain to students about systems administration, networking, GUI programming, and other essential ideas utilized in advanced programming.
