1、游戲貪吃蛇的JAVA源代碼1 文檔說明a) 本代碼主要功能為實現(xiàn)貪吃蛇游戲，GUI界面做到盡量簡潔和原游戲相仿。目前版本包含計分，統(tǒng)計最高分，長度自動縮短計時功能。b) 本代碼受計算機系大神指點，經許可后發(fā)布如下，向Java_online網(wǎng)致敬c) 運行時請把.java文件放入default package 即可運行。2 運行截圖a) 文件位置b) 進入游戲c) 游戲進行中3 JAVA代碼import java.awt.*;import java.awt.event.*;import static java.lang.String.format;import java.util.*;impor
