Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, etc.Java applications are typically compiled to Java 19.Below are the environment settings for both Linux and Windows.JVM, JRE, and JDK three are all platform-dependent because the configuration of each Operating System is different. But, Java is platform-independent. Few things must be clear before setting up the environmentwhich can better be perceived from the below image provided as follows: • JDK(Java Development Kit): JDK is intended for software developers and includes development tools such as the Java compiler, Javadoc, Jar, and a debugger. • JRE(Java Runtime Environment): JRE contains the parts of the Java libraries required to run Java programs and is intended for end-users. JRE can be viewed as a subset of JDK. • JVM: JVM (Java Virtual Machine) is an abstract machine. It is a specification that provides a runtime environment in which java bytecode can be executed. JVMs are available for many hardware and software platforms. Now let us discuss the steps for setting up a Java environment with visual aids. Let’s use the Windows operating system to illustrate visual aids. Steps: Here we will be proposing steps for three different operating systems as listed: Step 5: After downloading, run the jdk-8u Application( .exe file) and follow the instructions to install Java on your machine. Once you installJava on your device, you have to set up the environment variabl...

However, if you have your Java file outside the JDK/bin folder, it is necessary to set the path of JDK. There are two ways to set the path in Java: • Temporary • Permanent 1) How to set the Temporary Path of JDK in Windows To set the temporary path of JDK, you need to follow the following steps: • Open the command prompt • Copy the path of the JDK/bin directory • Write in command prompt: set path=copied_path For Example: set path=C:\Program Files\Java\jdk1.6.0_23\bin Let's see it in the figure given below: 2) How to set Permanent Path of JDK in Windows For setting the permanent path of JDK, you need to follow these steps: • Go to MyComputer properties -> advanced tab -> environment variables -> new tab of user variable -> write path in variable name -> write path of bin folder in variable value -> ok -> ok -> ok For Example: 1) Go to MyComputer properties 2) Click on the advanced tab 3) Click on environment variables 4) Click on...

Java is widely used in many applications and also provides computing power for numerous websites. In a previous article, we have seen the To run the Java application, there is a Java Development Kit (JDK) to install. And there are two environment variables to set. One is a path and the other is a classpath variable. Install JDK on Windows First of all, download the latest JDK from its official website of Install downloaded JDK software on your system. Note: In the case of Windows, by default, Java will be installed at directory path C:\Program Files\Java. After installation opens this directory path. You can find, there are two folders (jdk1.x… and jre ). Here is a complete JDK file hierarchy inside the Java folder. Java Environment Variables Setup Steps After installation, we need to set path and classpath environment variable for Java. Follow the steps on your Windows system as given below. • Right-click on My Computer. • Select Advanced System Setting. • Click on Environment Variables (at the bottom right corner). • There will be two environment variables, one is the User variable and another is a System variable. • If path and classpath variables are already present in System Variable, click on it to edit.

PATH is an environment variable that is used by Operating System to locate the exe files (.exe) or java binaries ( java or javac command). The path once it is set, cannot be overridden. The PATH variable prevents us from having to write out the entire path to a program on the Command Line Interface every time we run it. Moreover, the path is just a variable that stores a bunch of shortcuts. To execute java console-based programs in windows or Linux environments we have to use java and javac commands. The commands java and javac are not known to the operating system as we don’t specify where the executables reside. Hence, we need to specify the path where the executables are located. This is the reason we set the path and specify the path of the bin folder because the bin contains all binary executable files. After setting the path it can load all necessary items in the program including the compiler or interpreter itself. 3. In the system, variables click the New button. Now in the edit system variable, type variable name as JAVA_HOME and variable path as the path where the JDK folder is saved and click on OK button Usually the path of the JDK file will be C:\Program Files\Java\jdk1.8.0_60. 4. Now in the system variables go to the path and click the edit button. 5. Click the New button. 6. Now add the following path: %JAVA_HOME%\bin Setting Java Path in Linux • Open the terminal and enter the following command: sudo nano /etc/environment. • A file will be opened and add th...

In this article, you will understand the details about JAVA_HOME environment variable and how to set it on Windows 10. What is JAVA_HOME? By convention, JAVA_HOME is the name of an environment variable on the operating system that points to the installation directory of JDK (Java Development Kit) or JRE (Java Runtime Environment) – thus the name Java Home. For example: JAVA_HOME = c:\Program Files\Java\jdk1.8.0_201 Why is JAVA_HOME needed? To develop Java applications, you need to update the PATH environment variable of the operating system so development tools like Eclipse, NetBeans, Tomcat… can be executed because these programs need JDK/JRE to function. So the PATH environment variable should include JAVA_HOME: PATH = Other Paths + JAVA_HOMEOther paths are set by various programs installed in the operating system. If the PATH environment variable doesn’t contain a path to JRE/JDK, a Java-based program might not be able to run. For example, typing java in the command prompt showing this error: 'java' is not recognized as an internal or external command, operable program or batch file. Or Eclipse will fail to launch: How to set JAVA_HOME on Windows 10 Here are the visual steps to properly set value for the JAVA_HOME and update the PATH environment variables in order to setup Java development environment on your computer: 1. Firstly, you need to identify the Java home directory, which is typically under C:\Program Files\Javadirectory. Open My Computer and navigate to this ...
