Wonders of the World Java Code
I was assigned a special task by my professor to write a code on wonders of the world. The objective of the code was to read a provided set of images and database and replicate a system that would sort the images in specified orders. There were three types of specifications provided
1. Natural
2. Temperature
3. Accessibility
After selection another window opens in which the output is displayed, the output contains a series of images sorted in the selected order.
This “window-2″ has four buttons.
“First”, “Next”, “Previous” and “Last”, each does a task specified by its title and moves images in that order.
If you want the source code for this program, comment on this post.
