我编译出如下错误
C:\Downloads>javac b.java
b.java:5: class Snake is public, should be declared in a file named Snake.java
public class Snake extends JFrame
^
Note: b.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Note: b.java uses unchecked or unsafe operations.

class Snake is public, should be declared in a file named Snake.java
类Snake是public 的,必须声明一个文件叫Snake.java


你把程序代码放到Snake.java里面去就可以了
