Project Detail

Description

Create a Swing application that looks and behaves like a class already built.
Complete the following code by adding appropriate ActionListeners to each button or modifying the current ActionListeners to make this program complete. The functionality you are looking for is the following:
The Previous button will iterate through the data array moving to the previous array element each time the button is clicked and will then update the GUI with the newly selected data. If the Previous button is selected while the array is currently positioned at the first element, your program should then move the last element and update the display with the newly selected data.
The Next button will iterate through the data array moving to the next array element each time the button is clicked and will then update the GUI with the newly selected data. If the Next button is selected while the array is currently positioned at the last element, your program should then move the first element and update the display with the newly selected data.
When the Reset button is selected you should move to the first element in the array and update the display.
