First, you need to Locating the Environment Variables

1. Open up the system properties (WinKey + Pause) and you should see the below screen.

2. From the system properties, tab select the «Advanced» link. This should take you to the below screen.

3. From the System Properties screen select the «Advanced Tab». On this screen click the «Environment Variables» button.

4. You should now be seeing something like the below screen.

In the system variables section click in the «New» button.

In here enter the variable name : JAVA_HOME

Enter the variable value as the location of the java jdk installed in the previous section. (This is assuming you already have installed Java SDK. If you haven’t now is the time to do it)

For Example of my location below. (Please note the variable value will vary depending on your install location and version of the jdk)

Click ok to complete this action. Once completed you should see the JAVA_HOME variable in the list of system variables.

Next, you need to add the newly created JAVA_HOME variable on to your path.

To do this locate the «Path» variable in the system variables list. Select it and click the edit button.

This should bring up the below option.

Scroll to the end of the «variable value» field and append on the following

;%JAVA_HOME%\bin

Click «OK» to confirm and leave the edit path screen.

Once complete click «OK» to confirm and leave the Environment variables screen.

If it is you should see something similar to the below screenshot.

How to set the java path and classpath in windows-64bit

I have installed java on windows-64bit OS. but when I execute javac, it is failing with the

error message no such command is available». I have created following environmental variable

CLASSPATH C:\Program Files (x86)\Java\jdk1.6.0_05\lib

Add the appropriate javac path to your PATH variable. java.exe will be found under the bin directory of your JDK. E.g.

Before answering your question, just wann ans this simple question : Why we need PATH and CLASSPATH?

Answer:

1) PATH: You need to set PATH to compile Java source code, create JAVA CLASS FILES and Operating System to load classes at runtime.

2) CLASSPATH: This is used by JVM and not by OS.

Answer to your question :

Just make sure you have Modified PATH variable (Windows System Environmental Variable) so that it points to bin dir which contains all exe for example: java,javac and etc. In my case it is like this : ;C:\Program Files\Java\jre7\bin.

So, it doesn’t matter your system is 32 bit/64 bit until and unless you specify/Modify the PATH variable correctly.

Actually, the most conventional way of getting it done on Windows is

Path is one of the variables under «System Variables». This is where the system will search when you try to execute a command.

To verify, open the command window aka console window (for example, WindowsKey-R cmd.exe ) and run:

If the java bin folder is in the path, the system will find and execute the javac.exe file located there, and you will see your Java version. Something like:

Very Simple:

You need to set the two environment variables only; PATH and java

=>Right Click on My computer

=>Properties

=>Click on left hand side bar menu «Advanced system settings» => Click on «Environment Variables» button refer below fig.

=>Follow the below steps to Set User variable and System variable.

To Set User variable named as «PATH«

To Set System variable named as «java«

Click on «New» button in System variable tab.

Set the variable name as «java» and variable value as per your java installed version.(Shown in below fig.) Refer below images for the reference.

Find JDK Installation Directory

First you need to know the installation path for the Java Development Kit.

Open the default installation path for the JDK:

There should be a subdirectory like:

Set the JAVA_HOME Variable

Once you have the JDK installation path:

Note: You might need to restart Windows

The complete article is here, on my blog: Setting JAVA_HOME Variable in Windows.

What worked for me was adding the %JAVA_HOME%\bin to the Path environment variable with the JAVA_HOME environment variable pointing to the jdk folder.

You have to first Install JDK in your system.

JAVA_HOME = C:\Program Files\Java\jdk1.7.0 [Location of your JDK Installation Directory]

Once you have the JDK installation path:

Set JAVA Path under system variable

PATH= C:\Program Files\Java\jdk1.7.0; [Append Value with semi-colon]

In cmd (temporarily for that cmd window):

You might also need to add %JAVA_HOME%\bin to the path also (Also it depends on whether you run it from just the user or from all users, including System)

Control Panel > Java, Java tab, click the View button. In Runtime Parameters, put:

Or when you execute Java you can add that command line switch to the command:

One Image can fix this issue.

If you’re on a 64-bit version of Windows and you’ve installed the 32-bit JDK, besides adjusting PATH variables, you may need to adjust registry variables, too.

Now that I’ve updated those two registry values, my program runs flawlessly, with no more hiccups or complaints about a missing Java Runtime Environment (stemming from the registry).

There are solutions for Windows 7, Windows Vista, Windows XP, Linux/Solaris and other shells.

Example

Windows 7

Windows 7

Go to Control Panel\All Control Panel Items\User Accounts using Explorer (not Internet Explorer!)

Change my environment variables

(if you don’t have enough permissions to add it in the System variables section, add it to the User variables section)

Add JAVA_HOME as Variable name and the JDK location as Variable value > OK

Test:

We need to make a distinction between the two environment variables that are discussed here interchangeably. One is the JAVA_HOME variable. The other is the Path variable. Any process that references the JAVA_HOME variable is looking for the search path to the JDK, not the JRE. The use of JAVA_HOME variable is not meant for the Java compiler itself. The compiler is aware of its own location. The variable is meant for other software to more easily locate the compiler. This variable is typically used by IDE software in order to compile and build applications from Java source code. By contrast, the Windows CMD interpreter, and many other first and third party software references the Path variable, not the JAVA_HOME variable.

Use case 1: Compiling from CMD

So for instance, if you are not using any IDE software, and you just want to be able to compile from the CMD, independent of your current working directory, then what you want is to set the Path variable correctly. In your case, you don’t even need the JAVA_HOME variable. Because CMD is using Path, not JAVA_HOME to locate the Java compiler.

Use case 2: Compiling from IDE

However, if you are using some IDE software, then you have to look at the documentation first of all. It may require JAVA_HOME to be set, but it may also use another variable name for the same purpose. The de-facto standard over the years has been JAVA_HOME, but this may not always be the case.

Use case 3: Compiling from IDE and CMD

If in addition to the IDE software you also want to be able to compile from the CMD, independent of your current working directory, then in addition to the JAVA_HOME variable you may also need to append the JDK search path to the Path variable.

JAVA_HOME vs. Path

If your problem relates to compiling Java, then you want to check the JAVA_HOME variable, and Path (where applicable). If your problem relates to running Java applications, then you want to check your Path variable.

Path variable is used universally across all operating systems. Because it is defined by the system, and because it’s the default variable that’s used for locating the JRE, there is almost never any problem running Java applications. Especially not on Windows where the software installers usually set everything up for you. But if you are installing manually, the safest thing to do is perhaps to skip the JAVA_HOME variable altogether and just use the Path variable for everything, for both JDK and the JRE. Any recent version of an IDE software should be able to pick that up and use it.

Symlinks

Symbolic links may provide yet another way to reference the JDK search path by piggybacking one of the existing environment variables.

I am not sure about previous versions of Oracle/Sun JDK/JRE releases, but at least the installer for jdk1.8.0_74 appends the search path C:\ProgramData\Oracle\Java\javapath to the Path variable, and it puts it at the beginning of the string value. This directory contains symbolic links to the java.exe, javaw.exe and javaws.exe in the JRE directory.

So at least with the Java 8 JDK, and presumably the Java 8 JRE standalone, no environment variable configuration needs to be done for the JRE. As long as you use the installer package to set it up. There may be differences on your Windows installation however. Note that the Oracle JRE comes bundled with the JDK.

If you ever find that your Java JDK configuration is using the wrong version of the compiler, or it appears to be working by magic, without being explicitly defined so (without casting the spell), then you may have a symlink somewhere in your environment variables. So you may want to check for symlink.

How To Set Java, JRE and JDK Home Path and Environment Variables On Windows?

Java is a very popular programming language which provides a different component in order to run, develop Java applications. JRE or Java Runtime Environment is used to run Java application. JDK or Java Development Kit is used to develop Java applications. In this tutorial, we will learn how to set up Java, JRE, and JDK operating system path variables in order to work properly.

Locate JRE or JDK Path

Before starting the configuration we have to locate the JRE or JDK path. JRE or JDK generally installed on the Program Files or Program Files(x86) directory under the Java directory like below.

Locate JRE or JDK Path

and under the Java directory the JDK is residing.

Locate JRE or JDK Path

Set Java HOME_PATH Environment Variable

Open System Properties

In the system properties, we will navigate to the Advanced tab which provides the Environment Variables button like below.

Open Environment Variables

Below we can see the environment variables menu where we will create the JAVA_HOME system variable and set the path accordingly. We click to the New in order to create a new system variable.

Create New System Variable

Here we will set the Variable Name as JAVA_HOME and the Variable Value the path or Java, JRE or JDK which is C:\Program Files\Java\jdk-12 in this example. Then we will click OK.

Set JAVA Executable Path

Here we click to New which will add a new line to the existing values.

Here we will set the bin folder path which is C:\Program Files\Java\jdk-12\bin in this example.

Add Path System Variable

Then we will click OK and OK in the environment variables screen which will save and activated new path configuration.

3 thoughts on “How To Set Java, JRE and JDK Home Path and Environment Variables On Windows?”

What is the point in setting the JAVA_HOME to the path to the jdk install folder path if you then edit the Path variable and add the full path to the jdk bin folder? Shouldn’t you make use of the JAVA_HOME variable and add %JAVA_HOME%\bin to the Path instead.

@James Coffey, maybe the point of setting JAVA_HOME is just in preparation for GlassFish:
https://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/index.html
Still, the author could make use of it in Path as you say, but maybe the author is just trying to keep it simple.

Step 6 : Follow the Above step and edit the Path in System Variables add the following ;c:\Programfiles\Java\jdk-1.6\bin in the value column.

who will get a list of help doc

In order make sure whether compiler is setup Type in cmd

who will get a list related to javac

There are two ways to set java path

A. Temporary

If java is not installed, then you will see message:

javac is not recognized as internal or external command, operable program or batch file.

You can check that path is set if not error has been raised.

It is important to note that these changes are only temporary from programs launched from this cmd.

NOTE: You might have to run the command line as admin

B. Permanent

The path is now set permanently.

TIP: The tool «Rapid Environment Editor» (freeware) is great for modifying the environment variables and useful in that case
