All used third-party jar files to the project. Here is a question: How to create it? For example, to create a file which accepts and displays a string? Ie, I connect my jar to the project, create an object and pass it a string, and it outputs it. Or where can I read on this topic? NetBeans IDE. Thank.

  • Any Java tutorial already read? - Igor Kudryashov

    Read carefully. Not just a jar file, but connected to other projects. Essentially analog dll. - Kamenev_D
  • On the subject of the question: collect your jar, specify it in the project classpath and then you can use your library. - Peter Samokhin
  • Hmm ... really. Everything turned out to be easier than I thought. And do not tell me how to hide the code from the jar? It can be seen if you try to look at the code in the connected jar, then you can see only the ad, and in the body the inscription: Compiled code. - Kamenev_D
