I have a problem with the editor... my code runs on my eclipse, but the editor keeps returning error.

import java.util.; import java.math.;

public class dntt {

public static void main(String[] args) {


    Scanner scan = new Scanner(System.in);
    System.out.println( "enter meal cost");
    double mealCost = scan.nextDouble(); // original meal price

    System.out.println( "enter tip percent");
    int tipPercent = scan.nextInt(); // tip percentage

    System.out.println( "enter tax percent");
    int taxPercent = scan.nextInt(); // tax percentage

    scan.close();

    // Write your calculation code here.

      double tip = (tipPercent * 0.01 * mealCost);
      double tax = (taxPercent * 0.01 * mealCost);



    // cast the result of the rounding operation to an int and save it as totalCost 
    int totalCost = (int) Math.round(mealCost + tip + tax);

    // Print your result
      System.out.println( "The total meal cost is " + totalCost + " dollars" );

}

}
