Computer Science
A Java swing program that lets the user draw a line that can be individually deleted or moved.
make a JPanel to allow users to draw a line with their mouse, move the line to wherever, and delete each individual line chosen by the user.
Use JRadioButton and/or JComboBox in a separate JPanel to allow users to choose to draw, move, or delete a line.
The user should be able to have multiple lines at once
Whenever necessary, the user should be prompted with instructions on how to continue or what is wrong. (For example; conformation prompt for deleting a line, or which line the user wants to delete)
