A JAR file is a Java Archive File that is used to store a set of files in a compressed format. This type of file is typically used for distributing large applications or libraries. In order to run a JAR file, you will need to have the Java Runtime Environment installed on your computer.
You can then use the “java” command to execute the JAR file.
How to Run Executable Java (.jar) Files in Windows
- Find the location of your JAR file
- If it is in your current directory, you can just type “ls” to list its contents and find the JAR file
- Type “java -jar
” to run the JAR file - For example, if the JAR file is called “example
- jar”, you would type “java -jar example
- Press Enter to run the JAR file
- The program contained in the JAR file will now be running!
How to Run a Jar File Windows 10
If you’re looking to run a Jar file on Windows 10, there are a few different ways you can do it. The most common way is to use the Java Runtime Environment (JRE), which comes bundled with the Java Development Kit (JDK). You can also use an IDE like Eclipse or NetBeans.
The JRE is used to execute Java bytecode, which means that it’s platform-independent and can be used on any operating system that supports Java. To run a Jar file using the JRE, simply double-click on the file. If that doesn’t work, try opening it from the command prompt by typing “java -jar [filename]”.
If you’re using Eclipse or NetBeans, you can right-click on the file and select “Run As -> Java Application”. This will launch the file in a new window.
That’s all there is to running a Jar file on Windows 10!

How Do I Run a Jar File?
Assuming you have a JAR file named ‘example.jar’, you would run it by using the following command:
java -jar example.jar
This will launch the JAR file and execute its contents.
If your JAR file contains a main class, then it will be executed automatically. Otherwise, you’ll need to specify the main class to execute, like this:
How Do I Run a Jar Manually?
Assuming you have a jar file named ‘example.jar’, you can run it by using the following command: java -jar example.jar This will launch the jar file and execute its contents.
How Do I Run a Jar File in Windows 10?
If you have a JAR file that you need to run on Windows 10, there are a few different ways that you can do it. The most common way is to use the Java Runtime Environment (JRE). To do this, you first need to make sure that you have the JRE installed on your computer.
You can check this by going to Control Panel -> Add or Remove Programs and looking for an entry called “Java Runtime Environment” or “JRE”. If it’s not there, you can download it from the Oracle website.
Once you have the JRE installed, open up a Command Prompt window and navigate to the folder where your JAR file is located.
Then, type in the following command:
java -jar [name of JAR file]
This will launch the JAR file using the Java Runtime Environment.
How Do I Run a Jar File from Command Line?
Assuming you have a JAR file named ‘example.jar’, to run the file from command line, simply type:
java -jar example.jar
This will launch the JAR file using the Java Runtime Environment.
If you need to specify a different version of Java, use the ‘-version’ argument like so:
Conclusion
Java Archive (JAR) files are a type of compressed file used to distribute Java programs and libraries. JAR files are similar to ZIP files, but they use the .jar extension and can be run as executable files by double-clicking them.
To run a JAR file, you need the Java Runtime Environment (JRE), which is included with the JDK.
To create a JAR file, you first need to create a manifest file that contains information about the contents of the JAR. The manifest file is named MANIFEST.MF and is located in the META-INF directory.
The manifest file must contain the following two lines:
Manifest-Version: 1.0 Main-Class: MyClassName
The Main-Class line specifies the name of the class that contains your main() method.
You can then create your JAR file by running the jar command with the cvf options:
jar cvf myjarfile.jar *.
