Code Starter

TravelMode.java

package StatePatternLabOne;

public interface TravelMode {
    Object getETA();
    Object getDirection();
}

Walk.java

package StatePatternLabOne;

public class Walk implements TravelMode {
    @Override
    public Object getETA() {
        System.out.println("Calculating ETA (walking)");
        return 4;
    }
    @Override
    public Object getDirection() {
        System.out.println("Calculating Direction (walking)");
        return 4;
    }
}

Bus.java

package StatePatternLabOne;

public class Bus implements TravelMode {
    @Override
    public Object getETA() {
        System.out.println("Calculating ETA (transit)");
        return 3;
    }
