对不起，如果这是一个不好的帖子，这是我在本网站上的第一篇文章。在制作代码一个小时后，当我尝试运行它时，处理代码终于完成了。返回并使其有效的岸边(在Eclipse中一切都很好，但是当我查看控制台时，它说[1]'

获取错误
您已通过调用new eZ();成功初始化eZ对象，但您需要将e() method调用以打开帧。
public class ezMain {
public static void main(String args[]) {
eZ z = new eZ();
z.e();
}
}
一些建议：
- 请确保遵循Java的所有编码标准。
- 班级名称应以大写字母开头
- 遵循包名称策略
- 您可以在下面看到修改的类名称和软件包名称。
