General Features of Java
The Features of Java as a programming language will be explained later, but first, let us tell you about its general features.
Feature 1: Works Everywhere
The slogan for Java, given by Sun Microsystems, the company that developed "Java, is Write once, run anywhere."
Before the advent of Java, programs had to be written in different programming languages for other computers and operating systems. Still, since Java is designed to run in various environments, it can be used on Windows PCs, Mac PCs, Linux and other web servers, and even washing machines. Programs created in Java can run on embedded computers, such as a machine.
It is probably the most well-known feature of Java in general. Whether it is used in such a way or not is left aside, but as an engineer, you must know the term.
Feature 2. Adopted in systems of major corporation
Java is a programming language used in various places. Still, it is overwhelmingly used in large corporate systems, especially in banks and securities firms.
Banking systems are enormous, requiring hundreds or thousands of engineers to build over the years.
The essential requirements for such systems are stable, such as working as expected, security, and a system structure that does not break even when created by a large number of people.
Java is a very stable technology among programming languages, and it excels over other languages in aspects such as security.
Feature 3. Large-scale development
As reported above, Java is suited for large-scale development.
Large-scale development is creating a system with a large number of people.
Java is a programming language with a well-established object-oriented approach, which will be introduced later, and allows programs to be broken down into detailed functional components.
It is one of the reasons why Java is used in the systems of large companies.
Feature 4. Ease of Learning
Java is often thought of as a complex language, but Java is also straightforward to learn.
Because it is a language used in many situations and by many engineers, many books and information are available on the Internet.
There are also various Java community sites, so it is possible to learn Java independently. Also, since it is easy to create dynamic web systems, learning Java is more enjoyable than learning C or other languages because you can see your programs in action.
Feature 5: High Demand
Java engineers are in demand because Java is a programming language used in various settings.
According to surveys conducted by job sites and information-related websites, Java is always at the top of the list of popular programming languages. In recent years, Java has been adopted as the programming language for developing Android smartphones and tablets applications, making Java a programming language with a promising future.
Feature 6. Crushable
Learning Java also makes it easier to master other programming languages. This is because Java inherited much from pre-Java languages such as C and C++. Java has heavily influenced post-Java programming languages such as C# and Ruby.
If you learn Java, you will be able to use PHP, Ruby, or any other programming language in no time.
Feature 7. Android
Java's most notable current use is in Android, the smartphone operating system developed by Google and the world's most extensive operating system in terms of market share.
Java is the programming language used to create applications for Android smartphones.
Since Google provides valuable tools and libraries for developing Android applications, simple applications can be created quickly.
Suppose you have an Android smartphone or tablet. In that case, you can install your apps on it, making it easy to experience the fun of programming.
Furthermore, suppose you register as a developer on Google's website. In that case, you can distribute your apps so that people worldwide can install and use them. It is possible.
Features of Java as a Programming Language
Next, let's look at the Features of Java as a programming language.
There are various programming languages used in different situations depending on their characteristics. That is why it is essential to understand the features of Java as a programming language.
Although some parts may be a little difficult for beginners in programming, please review as much as you understand.
Feature 8. Object-oriented
Java is a programming language developed by Sun Microsystems in the U.S. and released in 1996.
It inherits much of its syntax from languages such as C and C++, which had been used in many situations up to that point. It has been improved and designed to overcome the shortcomings of those programming languages. One of those improvements is object-orientation.
Object-oriented programming is a crucial aspect of learning Java and is used today in many programming languages.
Understanding object-oriented programming in Java will be beneficial when learning other object-oriented programming languages.
It is difficult to explain what object-oriented programming is. Still, in straightforward terms, it means to treat everything in a program as an object.
Let's compare a program to a car. A car has a chassis, steering wheel, tires, engine, etc. Each of these parts is a separate component and object. Even if a tire goes flat, another tire can be put on the car, or winter tires can be placed on it to prevent it from slipping on snowy roads, etc. The car itself is designed to maintain its functions by changing or fixing parts without making any changes.
Object-oriented programming is a way to update or add functions to a program by changing or modifying some parts without altering the entire system, just like a car. Object-oriented programming is explained in detail on the following page.
A thorough explanation for beginners! What is object-oriented?
Feature 9. Garbage Collection
Java has a feature called garbage collection.
This feature did not exist in C, C++, and other languages. Previous programming languages had the drawback that they had to manage their memory.
For example, suppose you create an X variable and put the letter [A] in the variable. Suppose you do not clear the variable's contents. In that case, the character [A] will remain in the variable even when it is no longer in use. Because garbage collection automatically erases this unused memory, programmers do not need to worry about forgetting to erase unnecessary memory.
Feature 10. Fast Processing Speed
Java is a compiler-based language.
There are two types of programming languages: interpreted languages and compiled languages. A program must be converted into a language that a computer can process when executed. This is called compilation.
Interpreted languages are compiled when the computer executes the process. On the other hand, compiler-type languages are prepared in advance, so they do not need to be compiled when the laptop runs them. Interpreted languages do not need to be compiled when the program is written, eliminating one troublesome procedure. Still, in terms of computer processing speed, compiled languages are faster.
Feature 11. Extensive libraries
Most programming languages have libraries. It provides programs in a reusable form.
In most cases, libraries are provided free of charge. In most cases, libraries are provided free of charge so that developers can incorporate the functions provided by the library into their programs without having to go to the trouble of developing them.
Summary
This page summarizes the features of the Java language.
- Stability
- Abundant Uses
- Excellence as a programming language
These are probably the most important Features of Java. Java is usually ranked first in programming language rankings, as mentioned in the text.
