Здравей, това е моето решение, не е много правилно, но може да ти даде някои насоки, защото и мен ме затрудни този вход :Д

package Exam;

import java.util.Scanner;

public class walks {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter steps that you've walked today:");
        int steps = Integer.parseInt(scanner.nextLine());
        int stepgoal = 10000;

        while (steps >= stepgoal) {
            System.out.println("Goal reached! Good job!");
            System.exit(0);
        }

        String input = scanner.nextLine();
         if (input.equals("Going home")) {
             System.out.println("Enter steps that you've walked today:");
             int stepsmade = Integer.parseInt(scanner.nextLine());
             int stepsleft = Math.abs(stepgoal - stepsmade);
            System.out.println("You need " + stepsleft + " more steps to complete your daily task!");
        }
    }
}
