JAVA-Correct way not to read enter key

Question

I am making the problem 1168 - LED and would like to know if there is a way to make my in.nextLine() do not read the enter key,I managed creating a variable to read this enter,but I’m sure it is not the most correct way to do this.

https://www.urionlinejudge.com.br/judge/pt/problems/view/1168 (Uri problem for anyone who wants to see, I accept suggestions on code improvement as well).

import java.util.Scanner;

public class Uri1168 {
    public static void main(String[]args){

    int i,n;
    int total = 0;
    String enter;


    Scanner in = new Scanner(System.in);
    n = in.nextInt();

    enter = in.nextLine();
    for(i = 0;n>i;n--){
        total = 0;

    String v;
    v = in.nextLine();
    char[] num = v.toCharArray();

    for (char c : num) { // divide o numero em cada numero separado
        int f = Integer.parseInt(c+"");
        if (f==1){
            total += 2;
        }else if (f==2){
            total += 5;
        }else if (f==3){
            total += 5;
        }else if (f==4){
            total += 4;
        }else if (f==5){
            total += 5;
        }else if (f==6){
            total += 6;
        }else if (f==7){
            total += 3;
        }else if (f==8){
            total += 7;
        }else if (f==9){
            total += 6;
        }else if (f==0){
            total += 6;
        }




    }
    System.out.println(total+" leds\n");
    }

    in.close();
}
}
