Behaviour of the static and instance variables

B.java

public class B {
  
  public static void main(String… args) {
    System.out.println(“Value of var1 = “+B1.var1);

    object2.printData();
    B1.staticIncrement();

  }
}

  static int var1; //var1 = 0 only when class is loaded not for each    object created

    var1++;
  }
