Open word file through the . jar

Question

I have a calculator in . jar working perfectly ! My questions are: In the menu I have the "Source code" button and I would like to open a Word document with the source code of the program. I managed to accomplish this task but only on my computer! I saved the document . docx within another package on . jar, but I need to know how to "call it" by clicking the button to work on any machine ! This is my main question, but in addition, I wish someone could help me make that, when pressing the buttons of +,-,* and / the keyboard, they were associated with the Actionlistener Boots More, Boots and etc present in the code! I believe it’s necessary to use the Keylistener, but I don’t know how.. If anyone can help me, I’d be very grateful, especially with regard to opening the document. Here comes the code:

Answer 1

Use the relative path instead of the absolute path to open your . docx

File docx = new File("src/Imagens/codigoCalc.docx"); 

When exporting, make sure that inside your . jar you have the file in the address src/Imagens/codigoCalc.docx

PS: It is the custom of most programmers to leave inside the folder src only the files . java, the files that are program resources usually go in folders apart. I usually put in a folder called assets, consider the possibility of separating your files in a similar way, however, what you are doing is not wrong, it can only generate confusion if your code starts to get too large.
