Unsynchronized Thread Example

Un-Synchronized Threads means that the threads are running independently without gaining a "lock" on the shared resource.
In the below example the threads(t1,t2) both are accessing the common shared resource simultaneously and increasing the shared variable "count" in a random order rather than one by one( i.e. count getting increase from 0 to 49 by t1 and then count getting increase from 50 to 99 by t2). Here, count is getting increase to 14 by "Thread-0" and then count is getting increase to 15 by "Thread-1". 

public class Resource implements Runnable {
    private static int count=0;
    @Override
    public  void run() {
        try {
            Thread.sleep(1000);
            for (int i = 0; i < 50; i++) {
                System.out.println("count="+count+++"--->"+Thread.currentThread().getName());
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

public class Process {
    public static void main(String[] args){
        Resource sharedResource = new Resource();
        Thread t1 = new Thread(sharedResource);
        Thread t2 = new Thread(sharedResource );
        t1.start();
        t2.start();
    }
}
