Setting up the environment in Java

Java is one of the most common programming languages used by programmers. It is a class-based object-oriented language that is easy to use and allows “ write once and run anywhere”  programming facility. Java code can easily execute run through any Java Virtual Machine regardless of Computer Architecture.   Java 11 is the latest version. Hence, before you proceed you need to understand how to setup java environment,

Today in this blog we will discuss java environment settings for both Windows and Linux.  And try to fix all your doubts related to the setting environment in Java. JVM, JRE, and JDK All XL form are completely dependent because they are different in their configuration.  but Java is a platform that is completely independent.

We as java homework help providers assist students in their programming issues. And with the help of this blog, you can easily resolve all your doubts regarding this topic. For more programming content you can follow our official website and resolve all your programming issues and doubts.

There are few things which must be clear before setting up the environment are listed below:

Java-environment

JDK(Java Development Kit)

JDK is developed for software developers who need to write Complex algorithms and do Java assignment. And it also includes development tools such as  Java compiler, jar, Javadoc and debugger.

JRE(Java Runtime Environment)

JRE is intended for end-users and it contains a  path of Java libraries that are essential to run Java programs.  It can be easily defined as a subset of JDK.

JVM (Java Virtual Machine)

It is an abstract machine and with the help of JVM, we can provide a runtime environment in which Java bytecode can be executed easily.  Many hardware and software platforms are using JVMs as they are easily available. 

Steps to setup Java Environment for Windows

First of all, you need to download  Java 8 or the upper version. We have simplified setting the steps to to download java setup through our blog entry. And once you click on the highlighted section of this line which is about Java 8.  It will  redirect you to another window where you will get  another section same as given below:

Click on Windows 64 bit and Windows 86bit  as a highlighted section.

Once you download the setup .exe file follow the instruction and install Java in your PC.   When you are done with installation now you need to set up an environment variable.

Go to the Control Panel -> System and Security -> System.
 Now you need to  click on Environment variable as highlighted below:

After clicking on the environment variable button now you have to alter the path variable under system variable so that it could easily get the path of the Java environment.  You need to select the path variable and click the edit button as highlighted below

As you can see there is a list of different parts but you need to choose the path where Java is installed by default it is installed in “C:\Program Files\Java\jdk\bin” folder OR “C:\Program

select that particular path.  in case if you have to install Java in any other location then add that  path only

Just click on the Ok button and the window will say save these settings and you are done!! Check whether the installation was successful or not. Open Command Prompt and type javac -version.  If you see that Java is running on your PC or machine that means you have successfully installed the Java program.

 This was the simple set of  process for windows now we will learn how you can install Java in Linux

Steps for Linux

There are multiple ways of installing Java in Linux but we will follow the simplest and easy one.  For installing Java in Linux you need to install Open JDK.  It is a completely free and open-source  implementation of the Java programming language

Go to Application -> Accessories -> Terminal.

 Use command given below:
sudo apt-get install OpenJDK-8-JDK

For “JAVA_HOME” (Environment Variable) type command as shown below, in “Terminal” using your installation path…(Note: the default path is as shown, but if you have to install OpenJDK at other location then set that path.)
export JAVA_HOME = /usr/lib/jvm/java-8-openjdk

For “PATH” (Environment Value) type command as shown below, in “Terminal” using your installation path…Note: the default path is as shown, but if you have to install OpenJDK at other location then set that path.)
export PATH = $PATH:/usr/lib/jvm/java-8-openjdk/bin

If you want to check whether the installation was successful or not, type java -version in the terminal. And you will see that Java is running successfully on your machine

Popular Java Editors/IDE :

Notepad/gedit : Popular text return for writing Java program.  Notepad  is for Windows and gedit is  for Linux

Eclipse IDE : It is the most popular and used  IDE(Integrated Development Environment) for developing software in java.

Conclusion

I hope with the help of this blog post now you have cleared all your doubts related to the java environment and its setup. If you have any queries and suggestion please share in the comment section we will get back to you as soon as possible.
