Tip: To run the command, replace img1.png in main with the path of your own image.

Java makes a flowchart of a jigsaw puzzle game. It is a simple 3*3 jigsaw puzzle game.

Use swing to construct a framework to call the APPlet and then create several variables. 3*3: Eight bind small databases.
It can be determined that when the eight buttons are replaced by buttons, the button is converted into an image, and the size of the pattern is set, it will be done if the position is true, it mainly depends on how you deploy it. First, let's look at the SWING layout.
