What is Java?
Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This tutorial gives a complete understanding of Java. This reference will take you through simple and practical approaches while learning Java Programming language.
Java is a widely used programming language expressly designed for use in the distributed environment of the internet. It is the most popular programming language for Android smartphone applications and is among the most favored for edge device and internet of things development.Java 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 can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network. It can also be used to build a small application module or applet for use as part of a webpage.
Elements and Principles of Java
It is difficult to provide a single reason as to why the Java programming language has become so ubiquitous. However, the language’s major characteristics have all played a part in its success, including the following components:
- The code is robust. Unlike programs written in C++ and some other languages, Java objects contain no references to data external to themselves or other known objects. This ensures that an instruction cannot contain the address of data storage in another application or in the operating system itself, either of which would cause the program and perhaps the operating system itself to terminate or crash. The JVM makes a number of checks on each object to ensure integrity.
- Java is object-oriented. An object can take advantage of being part of a class of objects and inherit code that is common to the class. Objects are thought of as “nouns” that a user might relate to rather than the traditional procedural “verbs.” A method can be thought of as one of the object’s capabilities or behaviors. Being object-oriented is relatively common in today’s programming landscape, but back in 1996, only a handful of languages were implementing object-oriented concepts and design patterns effectively. The ability to develop with a language created from the ground up with object-orientation as its explicit purpose made Java an exciting platform upon which to program.
Why Choose Java?
Java was designed with a few key principles in mind:
- Easy to Use: The fundamentals of Java came from a programming language called c++. Although c++ is a powerful language, it was felt to be too complex in its syntax, and inadequate for all of Java’s requirements. Java built on, and improved the ideas of c++, to provide a programming language that was powerful and simple to use.
- Reliability: Java needed to reduce the likelihood of fatal errors from programmer mistakes. With this in mind, object-oriented programming was introduced. Once data and its manipulation were packaged together in one place, it increased Java’s robustness.
- Secure: As Java was originally targeting mobile devices that would be exchanging data over networks, it was built to include a high level of security. Java is probably the most secure programming language to date.
- Platform Independent: Programs needed to work regardless of the machine they were being executed on. Java was written to be a portable language that doesn’t care about the operating system or the hardware of the computer.
