Java is one of the widely used and dignified computer programming languages. In this, we discuss several Java tutorials using this anyone can become a pro in Java programming language from naive. But move to Java tutorials It is necessary to know what is Java?
This high-level programming language was originally developed by Sun Microsystems and released in the year 1995. Java runs on a range of platforms, such as Windows, Mac OS, and the various versions of UNIX.
Some of the most popular platforms use Java, for example, Facebook, Amazon, eBay, LinkedIn etc. Java is also used on many other devices like the ATM, televisions, Blu- ray players, automobiles etc. Java is virtually omnipresent. It is one of the widely programming languages.
Developed by James Gosling, it is an object-oriented language which is similar in fashion to C++, but with a more advanced and simplified platform and features. It is a class-based programming language. It runs on all the platforms and is free to access.
Java is concurrent which means you can execute many statements instead of sequentially having to execute it. In addition, Java follows the logic “Write once, Run anywhere”, which means the compiled code can run on all the platforms which support Java.
To put it simply, it is a computing platform where you can develop applications. With Java, you can enjoy plenty of features. Take a quick look at some of them.
Java: It’s features
As we would like it to be, it is simple to learn. It is designed in such a manner for easy learning. Complexities such as pointers, operating overload as in C++ or any other programming language has been eliminated. Mastering Java will be a piece of cake for a professional or a fresher.
As stated earlier, Java is an object-oriented programming language. Everything in here is considered to be an “object” and all the operations are carried out using these objects. These objects have its own state and behavior. Therefore, it is the most used computer programming language as it supports OOPS concepts.
Portability is one amazing feature of Java. What do we mean by portability? This means any application written on one platform can easily be ported to another platform. This unique feature of Java ensures it can run all platforms and it is not really dependent.
With the strong management that Java has, it eliminates errors as it checks the code during the compilation time and the run time. Memory allocation and releasing is taken care of by Java and this makes Java more robust.
Java is a secured and safe language for the one reason that all the code is converted in byte code after compilation. This means it cannot be read by humans, unlike the improved Kotlin that supports human readable code. It does not use any explicit pointer and runs the program inside the sandbox in order to restrict any activities from untrusted sources. It helps develop a virus-free, tamper-free systems/applications.
Java includes a feature that helps to create distributed applications. Using Remote Method Invocation or RMI, a program can solicit a method of another program across the network and get the output. Therefore you can get hands on these files by calling the methods from any machine on the internet.
Java is dynamic in nature and adapts to any environment, even if it is an evolving environment. Java programs carry a huge amount of run-time information. This is used to verify and solve access to objects. Its dynamic memory allocation feature ensures memory wastage is reduced and the performance of the application is enhanced.
Java is known to be high performing. Through the use of bytecode that can be translated into native machine code, Java is known to stand on the higher side of performance. The JIT or Just-In-Time compilers facilitate the high performance of Java.
To become a good programmer in Java you can learn it from various Java tutorials, but first of all, you need software on your computer that can run Java program.
The Java Development Kit or JDK
JDK is a tool that is necessary to compile, document and package Java programs. It includes JRE or the Java Run Time environment, that contains tools for Java programmers. The JRE refers to the run time environment where the Java bytecode is executed. The Java Development Kit is given free of cost. Along with JRE, it also has an interpreter/loader, a compiler (javac), an archiver (jar), a documentation generator (javadoc) and other tools needed in Java development. In short, it contains JRE + development tools.
Take a look at the three main parts of Java.
- The Java Virtual Machine: also known as JVM, it is an abstract machine. It is a specification that allows a runtime environment where the Java bytecode can be executed. Specification, Implementation, and Runtime Instance are the three notations it follows.
- Java Runtime Environment: also known as JRE, it refers to the runtime environment where the byte code can be executed. It implements the JVM (Java Virtual Machine) and gives all the class libraries and other support files that JVM uses during the runtime. JRE, therefore, is a software package that contains all that is necessary to run a Java program.
- Java Development Kit: JDK, just as what we had discussed is a tool that facilitates the compilation, documentation, and packaging of Java programs.
Here is a quick way to understand the three main parts of Java that explain the architecture and interrelationship between the parts.
Now that you have an understanding and the basic knowledge of Java, it is only a matter of time you can master the language.
