What is Java?

Java can be defined as a general-purpose language for programming and a computing platform. It is widely used because it is reliable, secure and fast. As of 2019, Java runs on 3 Billion devices globally and this makes it one of the most important programming languages to be learnt during college time. Originally released in 1995 as a “Write Once, Run Anywhere?", Java ran on several popular platforms as a mostly open-source freeware. Our online programming experts have made it further easy to learn. The goal in its creation was for a high-performance, object-oriented, dynamic and portable programming language that would also be secure, and Java has kept to these specifics throughout its evolution.

Key Features of Java Programming

jjjjJava programming language have had multiple configurations tailored to different platforms from embedded devices to enterprise servers, mobile phones, game consoles, and even supercomputers. Some of the key features of Java that makes it popular are listed below

  • Java’s major attractive qualities are its simplicity, portability and mattering. 
  • Java uses a universal bytecode whose instructions are equivalent to machine code and are executed by Virtual Machines (usually the Java Runtime Environment) written specifically for host hardware and any assistance on this is easy. This allows access to host-specific features e.g. graphics, networking, and threading. 
  • Java’s Standard Edition platform has a graphical user interface library called Swing which makes it possible to stipulate different looks at runtime, using the widget mechanism allowing manipulation of user interface appearance.
  • Java allows cross-platform look and feels, platform-dependent look and feels, and third-party look.
  • Java runs a simple memory model with automatic memory management performed by its Virtual Machines. This relieves programmers of the burden of manual memory management and reduces the likelihood of memory leaks, programme instability or crashing. However, it should be noted that automatic memory management would not prevent leaks where unused memory is referenced. 
  • Java programmers are able to execute structured query language instructions written in high-level language, all thanks to an enabling Application Program Interface i.e. routines, tools, and protocols used in building software applications, called Java Database Connectivity. Java Database Connectivity, while similar to Open Database Connectivity, is distinct for its design being specifically compatible with Java programs, as opposed to the language-independence of Open Database Connectivity.
  • The Java platform is able to allow standard-based interoperability and connectivity with heterogeneous objects using the Java Interface Definition Language. In other words, the Java Interface Definition Language is an Object Request Broker with Java Development Kit allowing distributed objects to interact on different platforms across a network. In this way, it is very similar to Remote Method Invocation, which provides remote communication between programs written in Java programming language and allows invocation of an object running on one Java Virtual Machine by another.

Our Java experts have a detailed understanding of all such interfaces and they are available round the clock to provide help with Java programming assignment. Our quick turnaround policy ensures that you receive Java assignment solution even during the tight timelines. The simplistic approach and well commented Java codes prepared by our online Java Programming experts ensure highest grades for the students.

 

Applications of Java Programming

Java finds its applications across sectors and devices. Listed below are some of the important applications of Java Programming. As a general purpose programming language, Java is suited for use on the World Wide Web using applets, small applications downloadable from Web servers on Java-compatible Web Browsers.

  • Mobile Applications - Java ME/ J2ME, Android Software Development Kit (SDK)
  • Desktop GUI Applications – Swing, JavaFX, Abstract Windowing Toolkit 
  • Web Applications – Struts, Servlets, JSPs
  • Enterprise Applications - Java Enterprise Edition
  • Embedded Systems - Embedded Java technologies are used in SIM cards, televisions, utility meters etc.

Our programming experts follow a simplistic approach while preparing the solutions. We assure you to provide the customized step-by-step well-commented codes for your Java assignments. Our access to multiple literary sources ensures that students achieve highest possible grades in the Java programming exams and assignments.

Key Challenges - Java Programming 

Java’s automatic memory management has a shortcoming in the area of memory leaks. These leaks are usually as a result of cache storage as opposed to a missing free or delete statement, thus Java’s automatic memory management has little to no effect in this regard. It’s indisputable that Java’s automatic memory management does, in fact, prevent certain types of memory leaks, but this can also be achieved by reference counting. Our Java Programming tutors have the experience and expertise to overcome these difficulties.

All this can be known by availing Online Java homework help service. Java’s automatic memory management is slow and this can be understood better with online programming assignment help.All Assignment Experts have the expertise and resources to share the solutions of all complex Java assignments within shortest of the deadlines.
