Take notepad for example. You can open a file with notepad (right click and open with, or double clicking on the file if it is already associated with notepad) and it will display the contents of a file. I want to be able to open an xml file with the program that I am writing so that it can do some parsing and give a desired output. What sort of ways are there to do this in java? Do I have to ask for an argument to be passed into the program when it is opened? Would this be easier in C++ or some other language? If you need any further information please let me know — this was the best way I could come up with to discribe my situation, which may be why my google searches have come up empty. Thank you in advance for your help!

You can associate an extension with a java jar and the file name will be passed as
args[0]It doesn’t get much simpler than that. I suggest you try it with a “hello world” program. 😉
