How to Run JAR files on Windows

JAR files are Java Archive files. It is a Zip version of Java Files that includes images, java class, audio, or other files, when the developer deploys the entire project, it saves classes and images files that are used in the Java project in the compressed form as a JAR (Java Executable File). JAR makes an archive for resources and classes. Additionally, it can restore or manipulate individual resources or classes from an archive. The JAR file content may be uncompressed using different tools such as WinZip, 7-Zip, or Windows default tool.

This write-up demonstrates the method to create and run a JAR file on windows. The following learning outcomes are expected:

• • Create a JAR File on Windows
  • Executing a JAR Files on Windows Using CMD?
  • Executing a JAR Files Using a Batch File?

  Create a JAR File in Windows

  The JAR is a Java executable compressed file that contains a Java project consisting of the images, code, and all the necessities in a project. To create a simple JAR file, follow up the listed steps:

  Step 1: Open Windows Command Prompt

  Search for “CMD” in the “Startup” menu and open Windows Command Prompt:

  

  Step 2: Open Java Project Folder

  Utilize the “cd” command to open the Java project folder in which you want to store java files in the form of a JAR file:

  

  We have used the “dir” command to list down the files inside the folder that are going to be compressed in a jar file:

  

  Step 3: Create JAR File

  We want to execute all java files in the form of a JAR file. For this purpose, we have utilized the provided command:

  The -cf option is the alias of “–create” and “–file” used to create the java file “Newjarfile”:

  

  Visit the directory where you have created JAR file or use “dir” command to check whether the JAR file is created or not:

  

  You can see that we have successfully created a JAR file in Windows.

  Method 1: How to Run JAR Files on Windows Using CMD?

  The JDK enables us to execute JAR files directly on the Windows operating system with the help of some commands. To execute the JAR file user can double click on it. But sometimes, this technique may not work due to some minor change in setting. We can execute it manually. Let’s check out how to run the JAR file on Windows:

  Step 1: Open Command Prompt

  Open the Command Prompt from the “Startup” menu by typing “Command Prompt”:

  

  Step 2: Run the JAR File

  Execute the provided command to run the JAR file from the command line:

  Here, you can see we have successfully run the JAR file from Command Prompt:

  

  Method 2: How to Run JAR Files Using a Batch File?

  Sometimes the JAR file is not executed by double clicking on it. Therefore, we can utilize a batch file to execute the JAR file on Windows. The batch file executes the command in a similar manner as the command prompt. But in the batch file, we can execute a collection of commands sequentially. It is mainly used to load and run programs. To run a JAR file using a batch file, utilize the provided instructions.

  Step 1: Create an Executable Batch File

  Here, we will be creating a batch file to run JAR file. To execute the JAR file, follow the listed instructions:

  • • Create a simple text document. For this purpose, right-click anywhere in the Java project folder where you have created the JAR file.
    • Move the pointer on the “New” option and select “Text Document” from the displayed option.

    

    Rename the text file and also replace the file extension “.txt” with “.bat” to save the file as a batch script. The batch script is a simple text file that is used to run different commands in sequence:

    

    Edit the file and paste the following command into a batch script. After that, press “Ctrl+S” to save changes. Java is used to execute to run java project, the “-jar” option specifies that we want to execute the JAR file:

    

    Step 3: Run Jar file

    Double click on the batch script to run JAR file on Windows:

    

    We have effectively described the method to run JAR files on Windows.

    Conclusion

    To run JAR files, you can use the command “java -jar .jar” in Command Prompt. However, you can create a batch file and save the command “jar -cf ” in the batch file. Simply, run the batch file to get the output of the JAR file. This post aimed to demonstrate a method for JAR files execution on windows. For a better understanding, we have also demonstrated the method to create a JAR file.

    How to Run Java Program?

    

    At first, check that Java is installed in your system and the path is properly set then we will see how to run the java program. If Java is not installed on the system or path is not defined properly, then we can’t run any Java programs on our system. After the JDK installation, compiling and running the java program is very easy.

    A java file is compiled using the javac command which generates a platform-independent bytecode that can be executed in any machine by a Java Virtual Machine (JVM). The bytecode is executed using the java command which executes the bytecode and produces the result.

    How to Run a Java Program Using Command Prompt and Notepad?

    Here we will be using Notepad and Command Prompt to run the Java programs. Let’s see the process step-by-step:

    • Create a new folder.
    • Go to the folder, and make the new Java file in that folder.
      • Press Alt+D, and just type Notepad there.
      • Notepad will open, now paste the java code given below in the Notepad and save it with extension java.

      Let’s see the above steps with images:

      Step 1: I have used the code given below for performing all the below operations. Open the Notepad and copy this code in the notepad and save that file with the extension .java.

      You can see in the below images that, I have written the java code and saved it as test.java. Now the new file will be created with the name test.java.

      

      

      

      Step 2: You can see that inside the Art folder, there is a java file with the name test.java.

      

      Step 3: Now press Alt+D , and you will get into the above search bar.

      

      Step 4: Type CMD and press enter key.

      

      Step 5: You can see that the CMD is open. Now type javac test.java , as you can see in the below image.

      

      Step 6: You can see that a new file has been created with the .class extension . The name of the file would be the name of the class you have used inside your program. In my case, I have used the Scaler as a class name.

      

      Step 7: Now again, open the cmd and type the command java Scaler as you can see in the below image.

      

      Step 8: At last, you will see that the content of the file has been displayed .

      

      The javac Command

      Java programs are compiled using the javac command. It takes .java files as input and generates bytecode.

      The java Command

      The java command is used to execute Java bytecodes. It takes bytecode as input, executes it, and outputs the result.

      Conclusion

      • We have seen how to run a Java program using notepad .
      • Create the Java file using Notepad and run it using java and javac commands.
      • Java programs are compiled using the javac command.
      • The java command is used to execute the Java bytecode generated as a result of compilation.
