Project Background
The game "Gluttony Battle" is a classic game, it is easy to operate, entertaining, since the computer to realize, by the majority of computer players love, this project is based on Java technology, developed a Simple operation, beautiful interface, more complete functionsThe "Snake" game. Through the development of this game, theLearn Java Technologycap (a poem)Familiar with software development processThe purpose of the
total requirement
This system is mainly to complete the basic operation of the game of Snake, so that users can practice and entertain themselves. The following requirements need to be met.
(1) Use the arrow keys to change the running direction of the snake.
(2) The spacebar pauses or resumes the game and spawns food in random places.
(3) When you eat food, you turn into a new snake body (the length of the snake becomes longer and the game continues).
implementation process
(1) Draw the form object.
(2) Static UI design (including snakes, food, game area and title area).
(3) Use keyboard listen event and timer to realize the movement of the snake.
(4) Realization of a small snake colliding with food.
(5) Define the variable to store the length of the snake, and traverse the array to realize the function of increasing the body of the snake.
(6) Exit condition: When the game points reach the specified score, the game is exited.

Project structure
This program is used for beginners to learn and encapsulates three classes, namelyDemo class, MyPanel class, Framework Ui classThe structure is simple and all methods are inMyPanelclass is implemented.
summarize
The design of this game is similar to the game "Snake Battle", the program in some of the functions of the implementation of many deficiencies, but the realization of the project on the Java novice has a great ability to enhance the actual combat.
Many problems were encountered while writing this project in Java, and in solving the problems, a deeper understanding and knowledge of object-oriented programming in java can be gained.
