Confusion in creating java objects.
sometimes we code for creating object of class like Car objCar = new Car (): but sometimes we have to put zero on braces like Car objCar = new Car (0): please explain the difference

the first one is using a no argument constructor and the second one is using a constructor with an argument.
it's just like passing an argument to a method. when the object is being created, the object will use the input you gave it (0 in your case) in some way to initialise the state of the object.

It depends from the constructor:
public Car()
{ }
or
public Car(int i)
{ }
