How Much Do you Know about Java? An Ultimate Guide for Beginners


Writing programs in Java can be a fun and rewarding hobby. It is also a very useful skill to have in the professional world. Being able to read, write, and modify Java programs is a huge asset to anyone wanting to work as a programmer.

There are several benefits of learning this language, including being object-oriented, having great security capabilities and being highly portable. This guide will walk you through all of the ways that you can learn Java quickly and easily, as well as what some of your options are if you want to take it to the next level.

Java is a general-purpose, concurrent, class-based, object-oriented computer programming language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers write once, run anywhere (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. Java applications are typically compiled to bytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2016, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers.

The latest version is Java 8, the only supported version as of 2016. It enhances and builds upon the previous version – Java 7 with some drastic changes in the language’s core features.

Java was originally developed by James Gosling at Sun Microsystems (which has since merged into 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.

Mastermind of Java – James Gosling

Java was first developed by a team of engineers called Green Team in 1991. The main objective of this team was to develop a language for digital devices such as set-top boxes, televisions, etc. Initially, it was named as ‘Oak’ after an oak tree that stood outside Gosling’s office. Later in 1995, the Oak Technology renamed it as Java. It is now owned by Oracle Corporation.

Why Java? Need of Java

Java was not developed to show the power and features of a high-level programming language. Instead, it has been designed to fix problems in existing languages like C and C++. The main goal of Java development team was to write a book named The Java Language Specification. In this book, they described the features and characteristics that were missing in the C++ language.

It is a programming language that was developed by James Gosling, which was intended to be used for the development of electronic devices like set-top boxes and embedded systems. It is also a general-purpose programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.

The first public implementation was Java 1.0 in 1995. It promised “Write Once, Run Anywhere” (WORA), providing no-cost run-times on popular platforms. On November 13, 2006, Sun released much of Java as free and open source software (FOSS), under the terms of the GNU General Public License (GPL).

Java has been a popular language for developing applications that can run on any platform because it is able to run on any system through the use of JVM (Java Virtual Machine). This means that you can write a program once and then run it on different platforms without having to recompile it again.

Java is one of the most popular and widely used programming language. This is an interesting guide for beginners to learn java programming from basics. For clearing the concept, we will write code in eclipse IDE and run it.

Java is one of the most popular and widely used programming language and platform. A platform is an environment that helps to develop and run programs written in any programming language.

There are many platforms for programming languages like Java, Netbeans: C, C++, PHP etc. Java is used by approx 10 Million developers worldwide to develop applications for 15 Billion devices supporting Java.

According to Sun, 3 billion devices run java. There are lots of applications and websites that won’t work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!

Introduction

In this article, we will learn about Java. Java is a high-level language and software-only platform. It was designed to have the look and feel of the C++ language, but it is simpler to use than C++ and enforces an object-oriented programming model.

Java was designed to allow development of portable, high-performance applications for the widest range of computing platforms possible. It accomplishes this by compiling the object code (code understandable to a computer) into platform-independent byte code. The byte code is then run on a Java Virtual Machine (JVM), which translates the byte code into machine instructions that are executed by the hardware on which it is running.

The use of Java Virtual Machine makes Java platform-independent. The JVM does this by providing a level of abstraction between the machine instructions for a specific computer architecture and the Java application being run on it.
