我在

行得到以下错误消息' illegal start of expression'

抛出FileNotFoundException

我做了一些研究，但没能解决它。你能帮忙吗?非常感谢，zan

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

Answer 1

抛出关键字前不应该有大括号:

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

Answer 2

throws使用不当

public static void main(String[]args) throws FileNotFoundException
{
 ..
}

最好使用try…catch

public static void main(String[]args) 
    {
      try
       {
        ..
       }catch(FileNotFoundException ex)
        {
          //
        }
    }
