“Standard Uses of Java”
We hear a lot about the programming languages and their productivity. Java is one of the popular and widely used languages. The people who belong to technology and programming understand the meaning and use of such languages. The other people are confused; do computers or software communicate using a language? It is important to clarify the myth and confusions for the people. The software and programs we use on computers, tablets, phones and other devices are not solid but codes. There are certain binary and digital codes that turns out to be graphics and different products for us. To form these codes, we need to have the languages like Java.
Putting a combination of codes with a specific pattern turn out to have an application or software. Eventually, that product helps us to solve problems, play games, do business and much more. The developers do not put the blocks and images in the web page, but use the codes to place everything in its place. Java being the favorite language among the rest of programming languages has its standard uses.
What is Java ?
Whether you’re a curious parent or a new coder, you’ve likely heard of the coding language Java before. ava is very commonly taught in high school, in introductory coding classes such as AP Computer Science. It’s often the first programming language many coders learn! Java is a programming language, designed to be concurrent, class-based and object-oriented, as well as a computing platform first released by Sun Microsystems in 1995. An enormous amount of applications and websites will not work unless you have Java installed, and more are created every day. Java was designed to have the look and feel of the C++ programming language, but is simpler to use 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.
Before exploring the reasons for Java’s enduring popularity, let’s review what Java is in more detail.
How Java Works ?
Java is a technology consisting of both a programming language and a software platform. To create an application using Java, you need to download the Java Development Kit (JDK), which is available for Windows, macOS, and Linux. You write the program in the Java programming language, then a compiler turns the program into Java bytecode — the instruction set for the Java Virtual Machine (JVM) that is a part of the Java runtime environment (JRE). Java bytecode runs without modification on any system that supports JVMs, allowing your Java code to be run anywhere.
Steps involved to write and execute a java program-
- First, we should have a java source code which must be saved with program.java extension.
- Then we use a JAVA Compiler to compile the source code to get java bytecode which must have a program.class extension. We can say that Java bytecode is a modified version of java source code.
- Now we pass the java bytecode through an interpreter called JVM (JAVA Virtual Machine) which will read every single statement at a time from java bytecode and convert it to machine level code and then will execute the code. We get the output only after JVM converts and execute the cod
4. JAVA has platform specified JVM interpreter such specified JVM for Linux, Windows, Macintosh which allow us to execute java programs at various platform easily.
Executing JAVA Program-
As we know the computer cannot understand human languages they only understand the codes in binary form i.e. 0 & 1. A program we write in high-level programming languages such as C++ and JAVA is called source program or source code which our computers don’t understand therefore the source code or source program we write in Java must be converted into the binary form which our computers should understand and execute. The translation of the source code into binary or machine code can be done using a programming tool called interpreter or compiler.
Java Compiler-
A compiler is a tool which converts the entire source code into machine code or any other intermediate code which our statement of the source code.
Java Interpreter
An interpreter is also a programming tool like compilers which converts the source code into machine code but interpreter works differently than a compiler. Interpreter only converts one statement of source code at a time and execute it right away. It doesn’t need executor to execute the program. The same process is followed for every other statement of the source code.
Open Source Development –
Since its first release, many additional features and libraries (a collection of pre-written resources for a given coding language) have been added to Java. As the internet became increasingly popular, more and more people began to contribute and grow Java’s collection of libraries and classes. This growth is largely thanks to Java being an open-source language — meaning that anyone can publicly contribute to the development of it. The open-source Java community and strong ecosystem of worldwide developers are largely responsible for helping the language evolve to where it is today.
The abundance of Java APIs and other tools built by the large developer community make it easy to write code to accomplish complicated tasks, since a lot of the basic backend code is packaged into APIs (platforms that allow different software applications to communicate) that anyone can use.
For example, Java Applets are small applications that are used to provide interactive features to web applications, and can be run from a web browser. These tools also allow for Java to be used in a large variety of applications, making the Java programming language very popular and widely used.
Why Java Matters-
If you are an enterprise application developer, you already know what Java is, and it’s likely that your organization already has thousands, even millions, of lines of production code written in Java. You will likely need some level of Java expertise to allow you to troubleshoot, maintain, and upgrade your existing codebase. However, it would be a mistake to view Java only in terms of legacy applications. The Java language forms the heart of the Android operating system, which powers by far the largest share of the world’s smartphones. Java is also among the most popular languages for machine learning and data science applications. Its robustness, ease of use, cross-platform capabilities and security make Java the language of choice for internet solutions in many enterprise shops.
In particular, Java technology is an ideal framework for developing web applications, the foundation for a digital business in any industry. Java application servers are web containers for Java components, XML, and web services, which interact with databases and provide dynamic web content. Java application servers form a stable deployment environment for enterprise applications with capabilities such as transaction management, security.
What Are the Applications of Java?-
There was a saying more than a decade old, any application that can be built on Java will be built on Java, which is now turning to be correct in this highly dynamic technological scenario. Nowadays, Java is deployed for automating tough tasks like developing complex software applications into a simple one. So, here is the list of some common uses of Java-
- Website Development
- Web Application, such as ecommerce applications
- Desktop GUI applications
- Mobile applications, including Android Applications
- Embedded application
- Gaming applications
- Enterprises applications
- Scientific applications
- Big Data applications
- Web servers and application servers
As per Oracle report, more than 3.0 billion devices are currently running on applications designed on Java. If you have any idea regarding a Java application then nothing is better than consulting a Java web development company. Thus, no business, whether its start-ups, enterprise, or entrepreneur on the earth, will decide to build their application on Java without knowing its benefits. Major companies like google Microsoft and many others also use Java for a number of purposes.
Let’s check out some of the major applications of java below
- Web Development- Although HTML and JAVASCRIPT are commonly used to write website and web application. Java has a number of packages and libraries that are useful web development. Java is well-suited to server-side web development, that is , programs that interact directly with server.
Example of some famous website build by using java :-AMAZON,WIKIPEDIA, TWITTER and YAHOO.
2. Android — Google Android Apps, and the Android operating system as well, are written using java and the Google Android API, which is very similar to the Java Development Kit (JDK). While Android application use a different JVM, the code is still written java.
3. Finance-E commerce — Many E-commerce websites as well as government , healthcare, insurance ,education and defense web application are built in java , making java programmer valuable in a large host of industries. Java’s implementation makes it a secure language, which is important for ecommerce websites that handle large amount of secure data like credit card numbers and user’s data. There are a number of features in java that make it a secure programming language.
For example –Java confines is a java application to the java execution environment, and doesn’t let it access system resources which helps prevent a security breach.
4. Games — Games and game Als are also written in java. Popular games like Minecraft are built using java too! Games use core java concepts like OOP (Object Oriented Programming) and multithreading. Multithreading is the simultaneous execution of two or more process, with the most efficient use of the CPU.
