1. The purpose of the experiment
Use and master most of the techniques of Swing programming
2. Experimental content
1. Create a class named MedleyGame, which inherits the JFrame class;
2. Then declare a panel object and a button object in this class. The panel object is used to add puzzle buttons, and the button object is the one that currently displays a blank picture. Button
3. Finally, write a main() method and a construction method MedleyGame() for this class, and set the relevant properties of the form in the construction method, such as the title, display position, and size of the form.
Three, the experimental environment
OS: Windows 10, compilation environment: eclipse
4. Description of the experimental process
Show some below 内联代码片.
