commons tasks in java

I want to start as junior in Java in a company but they ask me to present them some tasks that ensures that i am more than a junior.they offer me a task to create a Swing Gui with buttons and stuff.I have already a good knowledge of Java from University and some projects.
But on the way to create the logic and after a button stayed stacked i have learn about SwingWorker (because i have to do a task that runs in back) it was very interesting.
So my questions is so that i can present them some kinds of task i would like to ask you people.
What are the most common tasks that you do in work in coding.Example build a table and fill it with data and enable the right click (i have already done something like that they want more). What do you think that it would be good for me to present them and also that i learn something more for the future and so that i get the job.
Please just write only ideas or if you have working Experience what kind of tasks to do.Swing,Spring, JSP ,struts it doesn't matter all i will try and learn them them and i want the job.
All ideas suggestions are welcome.

Since they asked for Swing, you can ignore JSP, Struts and (to be honest) Spring.

Did they just ask you to write something?
Anything?

Seems a bit open to me (I hate those sorts of things).

Anyway, have a file with some data in it (csv).
Have a screen that displays the contents of this file in a table.
Have a button to allow a user to add a new Thing into the table and another button to save it all back into the file.

There's quite a lot there, and covers some of the key areas.

Hi there and thanks for your response .They don't just ask swing they give me an example and i have implement it.A gui with random number creation where the user adds the quantity of how many random numbers will be created, then i save it in a file then read it again in a table.What i have learn form this is Thread and SWingWorker class.
They said it could be anything from swing struts spring what ever but difficult so that they are sure about the hire. Like you said a bit open (you hate them Ialso hate them because they are not clear ).

What are some commons task you do in work so that i plug them in.

My current client is an airline, so it's booking related stuff.
You could mock up something like that I suppose, but it strikes me as a fairly hefty thing.
Depends how long you have.

Give me details

What details do you actually need?
Go on the web and look at an airline booking system.
Or hotel reservation one (that's probably a simpler option).
That's all the info you really need to mock up something.

Pick the technologies you want to learn and use those.

We also tend not to do stuff via PMs here. It's an open forum.

I would learn what all the Components do, and try to practice with each one.

You will probably get asked to work with databases, do file input/output functions (Saving and reading basic text files), maybe parsing functions with xml and know
about action listeners, setting and requesting focus to a button, including spellcheck, making a menu bar.

Most companies work with building databases to store information about products, students, schools, government type stuff. You should learn how to make a program that can
keep track of sales receipts, and stuff like that.

I am assuming you are talking about a Junior position at an office type space rather than some place like windows where you would be working intimately with the hardware.
