Starvation in the dining philosopher problem

I've been looking at a solution for the dining philosopher problem on wikipedia. The resource hierarchy solution

I understand how it works and how breaking the circular structure prevents deadlocks but how does the solution prevent starvation? Couldn't one or a few threads keep going while a few wont get to make progress?

If not, what prevents this from happening?

The implementation:

public class DinningphilMain {



    public static void main(String[] args) throws InterruptedException {


        int numPhil = 3;

        Philosopher[] phil = new Philosopher[numPhil];

        Fork[] forkArr=new Fork[numPhil];


        for (int i = 0; i < numPhil; i ++) {
            forkArr[i]= new Fork(i);
        }

        for (int i = 0; i < numPhil-1; i++) {
            phil[i]=new Philosopher(i, forkArr[i], forkArr[i+1]);
        }
        phil[numPhil-1]= new Philosopher(numPhil-1, forkArr[0], forkArr[numPhil-1]);

        for (Philosopher p : phil)
            new Thread(p).start();


    }
}

This is the philosopher class

import java.util.Random;

public class Philosopher implements Runnable {

    int sleep = 1000;
    int id;
    int eatTime= 500;
    Random rand = new Random();
    Fork left;
    Fork right;


    public Philosopher(int id,  Fork left, Fork right) {
        this.id = id;
        this.left = left;
        this.right = right;

    }


    private void think() {
        System.out.println("Philosopher " + id + " is thinking");
        try {
            int thinkingTime = rand.nextInt(sleep);
            Thread.sleep(thinkingTime);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

    private void getForks() {
        System.out.println("Philosopher " + id + " is picking up forks");
        try {
            left.get();
            right.get();
            System.out.println("Philosopher " + id + " has both forks");
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

    }

    private void releaseForks() {
        System.out.println("Philosopher " + id + " is putting down forks");
        left.release();
        right.release();
    }

    private void eat()  {
        System.out.println("Philosopher " + id + " is eating");
        try {
            Thread.sleep(eatTime);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }



    @Override
    public void run() {
            while (true) {
                getForks();
                eat();
                releaseForks();
                think();
            }

    }
}

This is the fork class

public class Fork {

    private int id;
    private Thread thread;

    public Fork(int id) {
        this.id = id;
        thread = null;
    }

    public int getId() {
        return id;
    }

    public synchronized void get() throws InterruptedException {
        if (thread != null) 
            this.wait();
        thread = Thread.currentThread();
    }

    public synchronized void release() {
        if (thread == Thread.currentThread())
            thread = null;
        this.notify();
    }

}
