system.outprintln("The value of myvar is"+this.myvar)
}

Answer / walking legend

as we generally know a pointer is used to point to the
address of a particular variable and access its value.
Similarly,this is a pointer which always points to the
current object.

Answer / madhu

'this' pointer is created when you create an object with
dynamic memory allocation. 'this' pointer will be created at
the time of object creation.
It holds the current object's address.
'this' cannot be used inside the static or a friend functions.

Answer / sohaibx

it is an implicit pointer holding the address of current object.
