我对制作按钮程序有疑问。所以，我做了一些简单的程序，如＆＃34;猜猜游戏＆＃34;，＆＃34;蛇游戏＆＃34;，＆＃34;俄罗斯方块＆＃34;等等和按钮程序。我想制作一个程序，当你单击按钮时，它会运行特定的程序。例如，如果您点击按钮1＆＃39;，则会运行＆＃34;俄罗斯方块。＆＃34;任何帮助都会很棒！
这是＆＃34;俄罗斯方块＆＃34;程序（代码）。

所以我希望第一个程序在＆＃39;按钮0＆＃39;单击并按下＆＃39;按钮1＆＃39;点击。顺便说一下，我正在使用Eclipse。
谢谢!!!
答案 0 :(得分：0)
由于每个游戏类都有own main method，你可以简单地想要开始游戏的主要方法。
由于main method is static不需要任何初始化，只需 -
GuessingGame.main();
或
Tetris.main();
