我使用eclipse，並得到這個錯誤有人可以告訴我，我哪裏出錯

Question

import java.util.Scanner; 
package reviewDistance; 

public class ReviewDistance { 

    public static void main(String[] args) { 
     int sec1; 
     int sec2; 
     int sec3; 
     int race; 
     Scanner input = new Scanner(System.in); 

     System.out.print("Enter the length of the first section of the race in kilometers:"); 
     sec1 = input.nextInt(); 
     System.out.print("Enter the length of the second section of the race in kilometers:"); 
     sec2 = input.nextInt(); 
     System.out.print("Enter the length of the third section of the race in kilometers:");; 
     sec3 = input.nextInt(); 
     input.close(); 

     race = sec1 + sec2 + sec3; 
     System.out.println("Length of the race: " + race + "km"); 

    } 

} 

我收到的錯誤代碼是這個，我不知道爲什麼！我很新到Java螺紋

異常 「主要」 java.lang.Error的：未解決的問題，編譯：

at reviewDistance.ReviewDistance.main(ReviewDistance.java:6) 

Answer 1

import java.util.Scanner; 
package reviewDistance; 

將其更改爲

package reviewDistance; 
import java.util.Scanner; 

包應該是在你的檔案文件的第一行
