Question

This is a java program.

The winter olympic paragraph just describes the problem.

The winter olympic console part is done. There is a second part where the output of the console side is written to a file and then read by the gui class which is called medal standings. The output of olympicstest should write to a file then the gui class will read the file and then populate the gui drop down box with the data from the olympic test. The gold winners in each event should show up in the gui when the event is clicked on. I am having trouble with getting the file output to write to a file. Thank you.

Winter olympic program

Create a program that stores 6 competitor names for 10 winter olympic events. The program should be able to accept time and scores. The top three in each event should be given a bronze, silver, or gold medal. A sort that goes from the dop down should be used for the top 3 scores of the events that are scored . For the time events the sort will will need to go from the lowest time to the highest time for gold, silver, and bronze. It should sort the scores or times of the events showing the medal winners only with the medal they won.

The scored events are ice hockey, aerials, curling, short half-pipe, half-pipe, figure skating, ice dancing, and pairs figure skating. The timed events are the bobsled and speed skating,

After the console program is done. Write a gui that has a drop down box in the middle that is labeled Olympic events. The event will need to be selected and then the corresponding medals for that event will show up on the bottom of the drop down list. Thanks for your help. 9 events can be hard coded in but for testing purposes 1 event should be able to be input.

The second part of this assignment is to have the output of the winter olympics file printed to a text file. The gui class then reads the file into an array or some type of object and that object will then be able to populate the set text parts of the drop down box with the output of the console side of the program.

Program below.
