You said that JARs only contains .class files and some other things. So, how is it possible to distribute Java source code like you say in this minute 1:12?

[@RaghavPal]

That's a good question. JAR files only contain compiled Java bytecode, so they cannot be used to distribute Java source code. However, there are a few ways to distribute Java source code: * **In a separate file:** You can distribute the Java source code in a separate file from the JAR file. This file can be a .zip file, a .tar file, or a plain text file. * **In a comment in the JAR file:** You can also distribute the Java source code in a comment in the JAR file. This is not as secure as distributing the source code in a separate file, but it is a way to make the source code available to those who want it. * **Using a source code hosting service:** There are a number of source code hosting services that allow you to store and distribute Java source code. These services typically provide a web interface where you can upload your source code and share it with others. Here are some of the popular source code hosting services: * GitHub * Bitbucket * GitLab * SourceForge * CodePlex I hope this helps

Hi Raghav, video is good. I would recommend you to put video on following topics 1. How objects are getting created in memory when we start running our bytecode. 2. How this abstaract and inheritance are working by using memory allocation and memory usage concepts If you covered on these it would be great for understanding more. Or could you suggest reference for learning this topics .I am very interested

[@RaghavPal]

Hi Karthick, I will plan on this

Hi Raghav, how to create a jar for the classes which are in src/test/java?

[@RaghavPal]

Hi Chandra, it should be done in the same way. Are you facing any errors. Moreover what is the scenario that you need to create jar. This is not very efficient always.

[@priyankagoyal2158]

Hi Raghav, one questions,since you have shown the practical of how to decompress/ or see the code of the jar file.So anyone can download others code(jars) from git or any other repository and decompress it and utilize it.Is it a security breach?

[@RaghavPal]

Hi Priyanka, there may be some restrictions on 3rd party jars

[@starSha1982]

The concept of the jar is clear now. Meanwhile, what is the difference between 'export as jar' and 'export as runnable jar' ?

[@RaghavPal]

Hi Shaji, When you export as jar, you can use this in any other framework or system and import the inner classes and functions and use them. When you export as runnable jar, you can run your program by running the jar directly

[@mr.RAND5584]

So portable. I can run it in any pc or laptop as long as there is java 8. I have run my javafx with mysql for three machine so amazing.

[@RaghavPal]

So happy to know this Marcial

Hi Raghav. I am stuck somewhere. I created a Java project and under package created a class file that has the main method. When I am trying to compile the project to create .jar file, it doesn't show the class file. It shows the package. This i am doing via Seal content from JAR Export page in eclipse. For Main Class, it blank. Please suggest.

[@RaghavPal]

Hi Gunjan, hope you have rechecked all the steps from the video. While creating the jar are you specifying the manifest class. Pls check the video again

[@gunjankapoor9163]

@@RaghavPal Thanks for replying back. Let me check again. Also, I had the main class.

[@gunjankapoor9163]

Hello, I would like to ask something.. I did a java project for my homework which is it works on console. And I have to give my project to school and they wanna see that works fine. If I only give them .jar, can they see that my project works right? Would that be enough? Thanks..

[@RaghavPal]

Hi Burcu, if you can package all your project + its dependencies in the jar, then surely you can share it.

[@brc9428]

Should be able to do it. Just try it out.
