So there is chance // that Object's state will be corrupted. public void getLine() { for (int i = 0; i < 3; i++) { System.out.println(i); try { Thread.sleep(400); } catch (Exception e) { System.out.println(e); } } } } class Train extends Thread { // reference to Line's Object. Line line; Train(Line line) { this.line = line; } @Override public void run() { line.getLine(); } } class GFG { public static void main(String[] args) { // Object of Line class that is shared // among the threads. Line obj = new Line(); // creating the threads that are // sharing the same Object. Train train1 = new Train(obj); Train train2 = new Train(obj); // threads start their execution. train1.start(); train2.start(); } }
