Hints

Read every line with nextLine() so bad lines don't break the Scanner.

Put the parseInt inside try, and count in the catch.

Solution explanation

The try/catch is inside the loop, so one bad line only skips that line.

Show solution

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = Integer.parseInt(sc.nextLine().trim());
        int sum = 0, skipped = 0;
        for (int i = 0; i < n; i++) {
            String line = sc.nextLine().trim();
            try {
                sum += Integer.parseInt(line);
            } catch (NumberFormatException e) {
                skipped++;
            }
        }
        System.out.println("Sum: " + sum);
        System.out.println("Skipped: " + skipped);
    }
}
