Use java to realize a simple jigsaw puzzle for your reference. The specific contents are as follows
First, let’s take a look at the renderings of this jigsaw puzzle:
Create a class named medleygame, which inherits the JFrame class; Then declare a panel object and a button object respectively in this class. The panel object is used to add puzzle buttons. The button object is the button that currently displays a blank picture; 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.
The Java project structure is as follows:
The specific java code is as follows:

}
}
}Here, the code program is finished. Let’s run it:
Follow the steps to save and then run:
The result is no problem. Click “next game” to refresh the game and arrange the pictures randomly:
So far, a simple puzzle game has been realized.
