    Default How can combing two classes together be made possible?

    i have two working classes which I've saved on two different files, but I want to combine the code into one file.

    One class is where I obtain general information from a user/customer
    The second class is where I take their more personal details i.e home address

    I want to keep the two areas of information separate.

    I will want to encrypt the data as well, can I do this via code both in idle mode and in transit mode using Java and how can I go about this?

    I am new to Java somewhat, was stuying it 12 years ago when I was at Uni, but later gave up as I decided to pursue another career, but now I am back, made a lot of mistakes in my life and I need to get on the road to making some serious money and I think becoming moderately decent at it, if not one of the best will help me. Rome wasn't built in a day and I am fully aware of that. It might take me 5 years or longer if I keep at it, but I hope I'll get it earlier and I can start applying for some jobs.

    A file can contain the code for more than one class. But only one of the classes can be public and its name must match the filename
    Often the code in two classes can be merged by copying the methods and variables from each class into the new merged class.
    A problem might be if there are methods with the same name or variables with the same name.
    Then there will be problems with all the other classes that use any of the methods of either class.

    Why do you want to merge the two classes into a single class? That is going the wrong way. It is more often to have code in one large class be migrated to separate, smaller classes.
    If you don't understand my answer, don't ignore it, ask a question.

    Hi, thank you for your rapid response, that explanation of public/private classes rings a bell.

    I am right back at the learning stage, so I will often be asking questions on approaches, which might be completely insane to the experienced programmer.

    I like what you did there, answered the question followed by recommending a different approach (the correct one! ha), that is exactly the kind of answers I am looking for, so I can gain varied knowledge of how I can make my idea come to life followed by the correct approach to take.

    Can you please give me an example of how I can go about this? In your own time of course.

    In the meantime will be playing around with other ideas.
