we want a java code for the following coding challenge: a road is divided into segments numbered from 1 to n
‐ within each segment, at any moment there can be at
most one car
‐ a car can change segments at every full second
‐ a segment can be entered only when during the past
second there was no car in it
‐ if it is not possible for a car to proceed it waits
‐ all segment changes occur simultanously
‐ each car has to perform a trip which consists of entering
the road at a given start segment, subsequently moving
from one segment to the next, and leaving the road at a
given end segment
‐ the arrival time of a car is when it finishes its trip
‐ all trips within a test case will have different start
segments  Calculate the arrival times of a number of cars, which perform
trips on one simple road.
- all trips start at time=1
Input:
Note: lines are separated by newline (\n)
number road segments (n)
number of cars (m)
startsegment,endsegment for car 1
…
startsegment,endsegment for car m
Example input
100
5
3,99
40,75
20,99
28,76
1,100
Example output
98,37,81,50,101
1 < n < 1000
1 < m < 1000
1 <= startsegment < endsegment <= n
Result:
arrival times of the cars, separated by comma, in the order of
the input

Lets assume we already have the following data structures:

package at.salento;

public class Car {
    private int startSegment;
    private int endSegment;

    private int arrivalTime;
    private int order;

    private int earliestStartTime; // introduced in level 2

    private int delay;

    private boolean entered = false;

    private boolean toRemove = false; // not used at the moment

    public Car() {
        this.startSegment = 0;
        this.endSegment = 0;
        this.arrivalTime = 0;
        this.order = 0;
        this.delay = 0;
    }

    public Car(int start, int end, int duraction) {
        this.startSegment = start;
        this.endSegment = end;
        this.arrivalTime = duraction;
        this.order = 0;
        this.delay = 0;
    }

    public Car(int start, int end, int duration, int order) {
        this.startSegment = start;
        this.endSegment = end;
        this.arrivalTime = duration;
        this.order = order;
        this.delay = 0;
    }

    public int getStartSegment() {
        return startSegment;
    }

    public void setStartSegment(int startSegment) {
        this.startSegment = startSegment;
    }

    public int getEndSegment() {
        return endSegment;
    }

    public void setEndSegment(int endSegment) {
        this.endSegment = endSegment;
    }

    public int getOrder() {
        return order;
    }

    public void setOrder(int order) {
        this.order = order;
    }

    public int getArrivalTime() {
        return arrivalTime;
    }

    public void setArrivalTime(int arrivalTime) {
        this.arrivalTime = arrivalTime;
    }

    public void increaseArrivalTime() {
        this.arrivalTime++;
    }

    public int getDelay() {
        return delay;
    }

    public void increaseDelay() {
        this.delay++;
    }

    public void setDelay(int delay) {
        this.delay = delay;
    }

    public int getTotalArrivalTime() {
        return this.arrivalTime + this.delay;
    }

    public boolean isEntered() {
        return entered;
    }

    public void setEntered(boolean entered) {
        this.entered = entered;
    }

    public boolean isToRemove() {
        return toRemove;
    }

    public void setToRemove(boolean toRemove) {
        this.toRemove = toRemove;
    }

    public int getEarliestStartTime() {
        return earliestStartTime;
    }

    public void setEarliestStartTime(int earliestStartTime) {
        this.earliestStartTime = earliestStartTime;
    }

    @Override
    public String toString() {
        String viz = "";
        for (int i = 0; i< startSegment; i++) viz += " ";
        viz += "|";
        for (int i = startSegment +1; i < endSegment; i++) viz += "-";
        viz += "|";
        // for (int i=)
        return String.format(" Car(start: %02d", startSegment)
                + String.format(", end: %02d", endSegment)
                + String.format(", arr.t.: %02d", arrivalTime)
                + String.format(", delay: %02d", delay)
                + String.format(", est: %02d", earliestStartTime)
                + String.format(", tot.arr.t: %02d", getTotalArrivalTime())
                + String.format(", order: %02d", order)
                + ") " + "\n";
    }
}

and we have filled an     private ArrayList<Car> cars; in a class Level1ComputationCGT. we now need a method that performs the required calculation
