Main.java:2: class main is public, should be declared in a file named main.java public class main

 

搜了很多解决办法，都是说类名要和文件名改成一样的，明明我改的确实是一样的鸭。。我还问了强者大哥大姐们，怎么改都是报这个错(；′⌒`)

。。。。。

后来一个同学告诉我，原来是PTA的平台问题：

类名文件名都得是 Main，最后改完终于成功啦

下面提交第一行要去掉

package he1;  import java.util.Scanner;  public class Main {  	public static void main(String[] args) { 		// TODO Auto-generated method stub 		int foot; 		//double inch; 		Scanner in = new Scanner(System.in); 		foot = in.nextInt(); 		//inch = (foot-32)*5/9; 		System.out.println((int)((foot-32)*5/9.0)); 		in.close(); 	}  }
