Comment

A condition in which the critical section (a part of the program where shared memory is accessed) is concurrently executed by two or more threads. It leads to incorrect behavior of a program.

public class PreventRaceConditions implements Runnable {
	private int inventory=1;
	long twoSeconds=2000;
	public static void main (String[] args) {
		PreventRaceConditions prc=new PreventRaceConditions();
		Thread firstThread=new Thread(prc, "First thread");
		Thread secondThread=new Thread(prc, "Second thread");
		firstThread.start();
		secondThread.start();
	}
	public void run() {
		if (inventory > 0) {
			try {
				System.out.println("Thread " + Thread.currentThread().getName() + " starting with inventory: " + inventory);
				Thread.sleep(twoSeconds);
			}
			catch (InterruptedException e) {
					// no op
			}	
			inventory--;
			System.out.println("Thread " + Thread.currentThread().getName() + " leaving with inventory: " + inventory);
		}
		else {
			System.out.println("Need to backorder! Thread " + Thread.currentThread().getName() + " found inventory with: " + inventory);
		}
	}	
}
