User interaction command-line

I have to make a booking system for a theatre for some school coursework.

I have little java experience so am learning as I create it.

The program will be command-line as I will gain no extra marks from a GUI so it would just waste time (even though I have already had a quick look at swing).



I want the program to give a list of options e.g:

1. Show todays date
2. show number of available seats
3. Close program

and the user would then input either 1, 2 or 3 into the CMD and hit enter for the relevant action to take place.



What do I need to learn for this?
Are there any tutorials in particular you would suggest i look at?

Here's a good place to start: Trail: Learning the Java Language (The Java™ Tutorials)

Read about the Scanner class and the several Reader classes for starters.

kind regards,

Isn't that just Oracles entire Java tutorial?
I've already covered the basics, it is just this part which I want to learn at the moment.

Thanks, I have came across these recently, I just wanted to make sure that this was what I was meant to be using.

The final thing I need to know before i think I know everything I need to create my program is how to make my own files which can be created, saved and then read by the java program I create. is this possible?


i.e. I want the program to be able to create/update a text file which will store the variables of the program (whether a seat is booked and who it is booked by etc...)

I want this so that all of the work is not lost when I terminate the program.

I don't think I explained very well.

For example, if a seat was booked using the program. The program would write to a text file: seat1Astatus = booked; seat1AUser = "Gary Green";

The text file could contain lots of these for each seat, when looking whther a seat is booked, we could just look up a variable listed in the text file.

By storing it in an external text file, I would be able to have the main java program shut-down without everything being lost (i.e. the variables for the seats are stored on the hard drive instead of in memory)

btw, the text file isn't necassarily going to be variable statements, it could just be booked, unbooked, unbooked, unbooked, booked etc... where a comma separates each seat.



Just ideas, I don't know if/how this can work

Maybe a Properties object can be of help; if you don't mind writing/reading non-text files, the Serializable framework can be a solution. It's time to start reading the tutorial ;-)

kind regards,

Jos

I've heard of properties files, I'll take a look, thanks
