Yes you can. Did you try compiling the code?

You have already created two objects with the references gb and gb1. Are you asking where else such objects can be created?

i think i m not making my question understandable to you the thing is
before completely creating the class how can its object(gb and gb1 in this case) be created inside it
or in other sense how is it possible that the object of a class can be created inside its own class

Because the class is the definition, the object is...well...an object.

I can describe a car to you; even show you a photograph or blueprints for it; without having to have an actual car. The object is the car; the class is the design document for the engineer (or, in Java's case, the JVM) that builds a car.

Isn't it funny how there's always time and money enough to do it WRONG?

do you mean constuctors ???

class obj{

float f ;

public obj(float f)
{
this.f=f;




}

public void main (String args[])

{
Obj gb=new Obj(3);
Obj gb1=new Obj(4);

System.out.println("first--->"+gb.b+"\n Second"+gb1.b);



}
}
