What is Java language?
Early in 1990, James Gosling, Mike Sheridan, and Patrick Naughton worked at Sun Microsystems to create Java language, an object-oriented programming language.
To continue working on this project, James Gosling and his associates established the Green Team team in 1991. The original plan was to create this programming language for digital appliances like TVs, set-top boxes, remote controls, etc. After some time, this notion was abandoned, and Java was created for internet programming.
What is its Purpose?
Web consoles, GUIs, web and mobile applications, game development, embedded devices, and desktop programs all use this language extensively. In addition to this, Java language is used to create software for gadgets. It is utilized in a variety of electronic equipment, including televisions, air conditioners, washing machines, and other appliances, in addition to computers and mobile devices. It makes it easy to use online shopping, banking apps, and registration forms.
What is the Basis?
The language is built on top of C and C++. Sun Micro systems created the first compiler for the language, which was written in C using some C++ libraries. Java files are converted to bit code format using a compiler, which the interpreter then executes. The Java Virtual Machine is the environment in which Java code is executed (JVM).
Why study Java language?
Other programming languages lack a number of characteristics that the Java programming language has. Because Java is updated frequently, it is more durable and adaptable. With each new release of the language, numerous new features are added. Java language has several features, some of which include:
Simple to learn: There are many online tutorials, like the one you are reading right now, and the syntax is simple.
Platform independent: it is operating system neutral, meaning it can run on any platform. For instance, a Mac OS program can run on Windows and vice versa.
Performance: Compared to other conventional interpreted programming languages, Java language runs much faster. Its code which has been compiled into byte code also referred to as machine code provides for quicker execution.
The elements of Java’s object-oriented programming (OOPs) are its fundamental ideas. OOP makes developing and maintaining software and applications easier by offering principles like these.
Object: An object is a component or a thing with a state and behavior. A dog, for instance, can be thought of as an object with a name, a breed, and a color. It exhibits actions like feeding and barking.
Class: A class is a grouping of various items. It is a blueprint that you can use to build as many different things as you want. Code is organized using classes in a similar manner to how produce is arranged in different sections in a grocery store.
Constructor: Although it has the appearance of a method, it is not one. It does not return any value and shares the same name as the class.
Inheritance: The idea of inheritance describes how one class might take on the traits and behaviors of its parent class.
Polymorphism: The process of carrying out a task in various ways is known as polymorphism. It enables programmers to use the same term in several contexts to mean different things.
Abstraction: it uses abstraction to hide internal details and display only the relevant and necessary information.
Encapsulation: Encapsulation is the binding or wrapping of code and data into a single entity (like a capsule). Encapsulation is exemplified via a Java class.
Features of Java
Java language has a number of attributes and capabilities, including:
- The simple syntax is extremely simple to grasp and understand.
- It is a powerful language.
- removes mistakes from the C and C++ programming languages
- Garbage collectors and exception handling are among the features included with the language.
- It is a portable language that may be used on any system.
- It offers security and supports multitasking.
- Although it is slower than C and C++, it offers the highest performance of any language.
