我正在使用eclipse并收到此错误，有人可以告诉我我要去哪里了

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");

    }

}

The error code I recieve is this and I don't know why! I am very new to Java

Exception in thread "main" java.lang.Error: Unresolved compilation problem:

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

Answer 1

import java.util.Scanner;
package reviewDistance;

change it to

package reviewDistance;
import java.util.Scanner;

package should be the first line in your jave file
