Set The JAVA_HOME variable In Microsoft Windows 8

From step 1 to step 10, you can study at the Set Up A Java Development Kit In Microsoft Windows 8 With Picture

1. Let us locate the directory where the JDK is installed on our system, and note down the path to this directory.
   
2. Open the Start menu and click "All apps" down arrow button in the bottom-left corner.
   
3. Scroll through the list of apps and click "Control Panel" on the "Windows System".
4. The Control Panel will appear on the screen.
5. Under "View by:" on the right side, click "Category", 
6. After then select the “System and Security” section.
7. then select the “System” section on the right side.
8. In the System window, click on Advanced System Settings on the left sidebar.
9. In the System Properties window (Advanced tab):
10. Click the Environment Variables button.

Add JAVA_HOME Variable In Microsoft Windows 8

This following step to add JAVA_HOME variable:

11. Under the System Variables section, click a New button to create a new one.
    
    
    
    
    
12. In the Variable Name field, type JAVA_HOME.
    
    
    
    
    
13. In the Variable Value field, enter the path to our JDK installation directory (e.g., in this post C:\runtime\Java\jdkX.X.X_XX\). Then press OK button.
    
    
    
    
    
    

Add %JAVA_HOME% To The Path Of Windows Environment Variable

This following step to add %JAVA_HOME% to the Windows Environment Variable:

14. In the System Properties window, select the Path variable under the System Variables section. Click Edit button, 
    
    
    
    
    
15. and add %JAVA_HOME%\bin to the list of paths if it’s not already there. Click OK  button.
    
    
    
    
    
16. Click OK  button to apply the changes and restart the computer to ensure the changes take effect.
    
    
    
    
    
    
    
    
    
    

Check %JAVA_HOME% Has Installed Successfully

17. Start Command Prompt window then use the following command to check the %JAVA_HOME% has been added correctly.
    
    
    
    
    
18. echo %JAVA_HOME%. You should see the path to your JDK (or JRE) installation location without bin folder.
    
    
    

after this you can follow and practise this optional step below according to your condition:

Edit JAVA_HOME

11. Under the System Variables section, found JAVA_HOME variable, click Edit button to modify the existing variable.
    
    
    
    
    
12. change the Variable Value field with enter the path to our JDK installation directory (e.g., in this post C:\runtime\Java\jdkX.X.X_XX\ ). Then press OK button.

How to Creating A JAR File Using the Command Line

Prerequisites

Before you begin, ensure you have the following tools on your system:

• Java Development Kit (JDK) installed and configured in your system's PATH. You must download JDK from the official Java website, if you don't have JDK. JDK is required for compiling Java code (javac) and running JAR files (java).
  If you want to learn default Java Path For Windows And Linux Environment, click Default Java Path Environment >
  You must setup PATH environment, click Set The JAVA_HOME variable >
  To check the Java version, click How To Check Your Java Version >
• A Text Editor, for example Notepad: To write your Java code and potentially to write a manifest file.
• A Terminal or Command Prompt: To execute compilation and JAR creation commands.

Assumption

• Ensure you have a Java class with a main method ( after You compiled a Java source code File ), which serves as the entry point for your Java simple application (JAR) or Java simple program (JAR). You can use this Java exercise, click Hello World In Java and then you must compile the Java Program, click How To Compile Java 1.
• Ensure you understand to using Text Editor and a Terminal or Command Prompt. If you are not understand to using Text Editor and Command Prompt, read Notes below.

The Steps

1. First we navigate to the root directory of your Java class files project directory. In this example the directory is D:\demo\java\GettingStarted\HelloWorld.

navigate to the root directory
of your Java class files project directory

list your root directory
of your Java class files project directory

2. Create a Manifest File: Open your Text Editor and then create a text file (e.g., manifest.txt) and add the Main-Class entry. Make sure there's a newline at the end of the Main-Class line. The full contents Of Manifest.txt example:

Main-Class: helloWorld

Class-Path: helloWorld.jar

Notepad program show

Type Manifest.txt example contents

3. Save file As Manifest.txt in directory D:\demo\java\GettingStarted\HelloWorld\.

click File > Save As menu

Navigate to D:\demo\java\GettingStarted\HelloWorld\.
And then type Manifest.txt in File name box.

click Save button

file Manifest.txt has saved

4. Create the JAR File

Now, use the jar command to package your compiled .class file(s) and the manifest file (if applicable) into a single .jar file, for example:

jar cvfm helloWorld.jar helloWorld helloWorld.class

The options and arguments used in this command are: 

-c: Creates a new archive.

-v: Provides verbose output, listing the files as they are added.

-f: Specifies the filename of the JAR archive (helloWorld.jar).

-m: Specifies the manifest file to use (manifest.txt).

Create the JAR File

The JAR file has created

5. Run the Executable JAR

If you created an executable JAR, you can run it directly from the Command Prompt:

java -jar helloWorld.jar

You should see the output: Hello World

Run the Executable JAR

The Executable JAR has succeed to run

Notes

• Of course, you can use Java IDE or other Java Build Script Tools to create a JAR.
• To learn about open Command Prompt in step 1, 
• click How To Launch Command Prompt 
• or click How To Launch Command Prompt In Windows 8.
