java - FIleNotFoundException - 表达式的非法开始 - NetBeans

Question

我在第 行收到以下错误消息“表达式的非法开始”

throws FileNotFoundException

我做了一些研究，但无法修复它。你能帮我吗？非常感谢赞

import java.io.FileNotFoundException;
    import java.io.File;
    import java.util.Scanner;
    import static java.lang.System.out;

    public class training{
        public static void main(String[]args){

            throws FileNotFoundException{

            Scanner diskScanner = new Scanner(new File("occupancy"));

            out.println("Room\tGuests");

            for(int roomNum = 0; roomNum < 10; roomNum ++){
                out.print(roomNum);
                out.print("\t");
                out.println(diskScanner.nextInt());
                }
            }
        }
    }

throws 关键字前不应该有花括号:

public static void main(String[]args) throws FileNotFoundException {
                                     ^-- no curly brace

请注意，类应始终以大写字母开头。
