Add java to path windows 10

In this post, we will see about how to set java path in windows 10 using cmd. To set java path, you need to first understand about JAVA_HOME and how to set JAVA_HOME in windows 10.

Let’s first understand about JAVA_HOME and then we will see how to set JAVA_HOME in windows 10.

What is JAVA_HOME?

JAVA_HOME is environment variable which contains installation directory of Java development kit(JDK) or Java Runtime environment(JRE). This environment variable is setup at operating system level.

JAVA_HOME=C:\Program Files\Java\jdk—11.0.9

Why do you need JAVA_HOME?

JAVA_HOME environment variable points to directory where java is installed on your system, so many java based applications such as TOMCAT use JAVA_HOME environment variable to locate java executables.

How to set JAVA_HOME in Windows 10?

Locate JDK on your machine.
- If you are using 64-bit java, then it will be in C:\Program Files\Java\
- If you are using 32-bit java, then it will be in C:\Program Files (x86)\Java\
Open windows search, type environment and click on Edit the system environment variables.
In System properties dialog, go to Advanced tab and click on button Enviroment Variables.
In System variables, click NEW... button to add JAVA_HOME environment variable.
Provide variable name as JAVA_HOME and value as Java installation directory.

Now let’s see how to set java in path environment variable in windows 10.

In System variable window, locate Path and click on Edit....
Double click on the empty row and add %JAVA_HOME%\bin.

Here, % symbol is used to locate JAVA_HOME environemt variable and \bin provides location for java.exe and h=javac.exe
Close the command prompt and launch again.
Check java version as below:

That’s all about How to set java path in windows 10.

I got a new laptop with Windows 10 and I want to set it up so I can use java and javac from the command line.

I have searched online but all the guides are for previous versions, and I don’t want to mess around with something I don’t understand.

Just set the path variable to JDK bin in environment variables.

Variable Name : PATH 
Variable Value : C:\Program Files\Java\jdk1.8.0_31\bin

But the best practice is to set JAVA_HOME and PATH as follow.

Variable Name : JAVA_HOME
Variable Value : C:\Program Files\Java\jdk1.8.0_31

Variable Name : PATH 
Variable Value : %JAVA_HOME%\bin

Its still the same concept, you’ll need to setup path variable so that windows is aware of the java executable and u can run it from command prompt conveniently

Details from the java’s own page: https://java.com/en/download/help/path.xml
That article applies to: •Platform(s): Solaris SPARC, Solaris x86, Red Hat Linux, SUSE Linux, Windows 8, Windows 7, Vista, Windows XP, Windows 10

if you have any version problems (javac -version=15.0.1, java -version=1.8.0)
windows search : edit environment variables for your account
then delete these in your windows Environment variable: system variable: Path
C:\Program Files (x86)\Common Files\Oracle\Java\javapath
C:\Program Files\Common Files\Oracle\Java\javapath

then if you’re using java 15
environment variable: system variable : Path
add path C:\Program Files\Java\jdk-15.0.1\bin
is enough

if you’re using java 8

create JAVA_HOME

environment variable: system variable : JAVA_HOME
JAVA_HOME = C:\Program Files\Java\jdk1.8.0_271

environment variable: system variable : Path
add path = %JAVA_HOME%\bin

Ответы

Для добавления пути к JDK (Java Development Kit) в переменную среды PATH в Windows, следуйте этим шагам:

Откройте «Системные настройки» в Windows. Это можно сделать несколькими способами, например, нажав на клавишу Windows и искать «системные настройки» или нажав правой кнопкой мыши на значке «Этот компьютер» и выбрав «Свойства»
В меню слева выберите «Дополнительные параметры системы»
Нажмите на кнопку «Переменные среды» в нижней части окна.
В разделе «Системные переменные» найдите переменную Path и выберите «Изменить»
Нажмите на кнопку «Новый» _ и введите путь к JDK. Обычно это путь к папке _»bin» в установленной JDK, например: C:\Program Files\Java\jdk1.8.0_291\bin
Нажмите «ОК» во всех открытых окнах, чтобы сохранить изменения.

После этого вы можете использовать команды java и javac в командной строке Windows из любого места в файловой системе.

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_HOME

Other 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\Java directory. Open My Computer and navigate to this directory, you will see:

Here, the home of JDK is under C:\Program Files\Java\jdk1.80_201. The version number may vary, depending on the JDK you installed.

2. Open the System Environment Variables dialog by typing environment in the search area on Start menu. Click the suggested item Edit the system environment variables:

The System Properties dialog appears, click the button Environment Variables.

Then you will see this dialog:

3.Create the JAVA_HOME environment variable by clicking the New button at the bottom. In the New System Variable form, enter the name and value as follows:

Click OK, and you will see the JAVA_HOME variable is added to the list.

4.Update the PATH system variable. In the Environment Variables dialog, select the Path variable and click Edit:

Then in the Edit environment variable dialog, double click on the empty row just below the last text line, and enter %JAVA_HOME%\bin as follows:

The percent signs tell Windows that it refers to a variable – JAVA_HOME, and the \bin specifies the location of java.exe and javac.exe programs which are used to run and compile Java programs, as well as other tools in the JDK.

Click OK button to close all the dialogs, and you’re all set. Now you can open Eclipse or NetBeans to verify. Or open a command prompt and type in javac –version, you should see:

NOTES:

You can add the path to the bin directory of Java home directly into the PATH variable. But it’s strongly recommend to follow the above steps to setup a JAVA_HOME variable because many Java programs depend on it.

When you installed a JDK, you might not need to update the system variable because the installer already did it for you.

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.

Below is the procedure for setting the path for both Windows and Linux:

Setting Java Path in Windows

1. Go to the Search box and type advanced system settings in it. Now click on the View advanced system settings.

2. Select the Advanced tab and then click environment variables.

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 the following command to that file:

JAVA_HOME = "YOUR_PATH".

Replace YOUR_PATH with the JDK bin file path.
Now restart your computer or virtual machine that you are using (or) reload the file: source /etc/environment
You can test the path by executing

 echo $JAVA_HOME

If you get the output without any error, then you’ve set the path correctly.
If you get any errors, try repeating the procedure again.
