this.weight=100;
}
}
class Dog extends Animal implements Serializable
{
String name;

Dog(int weight,String name)
{
//super(weight);
this.weight=weight;
this.name=name;
tmp=77;
}
public void change()
{
weight=100;
}
}
This code results
Weight:100
Name:Puppy
Static Variable tmp:77
I don't know how it results tmp as 77?
Somebody make me clear about this..
