Here is a Sample Run, There are a little bit of errors because I only used JGRASP as my compiler. No Drag and drops.
Running Smoothly using JGRASP
Compute Total Action Performed
Sample (3) Listed Coin @ index with JText Disabled after Performed
Delisting a coin is simple, we'll have to use the 0-20 number indexes. The program still have some Flaws, the purpose of making this program is to understand the basics of GUI, by this - I was able to debug it manually. Thanks to Jgrasp lol.
