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

 

搜了很多解決辦法，都是說類名要和文件名改成一樣的，明明我改的確實是一樣的鴨。。我還問了強者大哥大姐們，怎么改都是報這個錯(；′⌒`)

。。。。。

后來一個同學告訴我，原來是PTA的平台問題：

類名文件名都得是 Main，最后改完終於成功啦

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();
	}

}
