Java Timer loop execution?

[Booch]

Before anything. Here's the question I'm tackling. The question itself is relatively easy to do but I kinda feel like pimping it out a bit


Wanted to see if I can loop my whole main in my Run class using real-time(seconds) and then saving the result into an array and printing the array after X loops

 

I've never used Java Timer and oracle docs just hurts my eyes sometimes and would be cool to get any suggestions. Want to experiment some crazy shit

Just do what the assignment asks for. Storing the data in an array isn't necessary for the results are quite obvious. Just use a new thread to determine what amount of time you'd like execution to occur on.

import java.util.Random;
 
/**

public class VehicleSimulator {
 
    private static final Random RANDOM = new Random();
 
    public static void main(String[] args) {
        VehicleSimulator camry = new VehicleSimulator(1, 100, 20, 1);
        camry.start();
    }
 
    /**
     * Separator
     */
 
    private int passengers, fuelCap, mpg, gear;
 
    private boolean acc, running;
 
    public VehicleSimulator(int passengers, int fuelCap, int mpg, int gear) {
        this.passengers = passengers;
        this.fuelCap = fuelCap;
        this.mpg = mpg;
        this.gear = gear;
        this.running = true;
    }
 
    private void start() {
        new Thread(new Runnable() {
            @Override
            public void run() {
                while(running) {
                    accDec();
                    changeGears();
                    debug();
                    try {
                        Thread.sleep(1000L);
                    } catch(InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        }, this.getClass().getName()).start();
    }
 
    private void accDec() {
        if(gear == 1) {
            /**
             * Cannot decelerate at this point!
             */
            acc = true;
            return;
        }
        acc = RANDOM.nextBoolean();
    }
 
    private void changeGears() {
        int change = acc ? +1 : -1;
        gear += change;
    }
 
    private void debug() {
        System.out.println("Accelerate: " + acc + "     Gear: " + gear);
    }
 
}
