Demo Code

 

class StaticDemo {
    public static boolean oneValueForAllObjects = false;
}
 
public class Main {
    public static void main (String[] args) {
        StaticDemo sd1 = new StaticDemo();
        StaticDemo sd2 = new StaticDemo();
        System.out.println(sd1.oneValueForAllObjects);
        System.out.println(sd2.oneValueForAllObjects);
        sd1.oneValueForAllObjects = true;
        System.out.println(sd1.oneValueForAllObjects);
        System.out.println(sd2.oneValueForAllObjects);
    }/*from w  w w  .  jav  a2  s.c  o m*/
