what is constructor chaining ?????

Your Answer

calling superclass constructor while creating sub class object is known as constructor chain.
For example:
class Person   //super class
{
 String name;
 Person(String n)
 {
   name=n;
 } 
}
class Teacher extends Person    //subclass
{
 String sub;
 Teacher(String n,String s)
 {
  super(n);
  sub=s;
 }
}
class Test
{
 public static void main(String[] args)
{
 Teacher t=new Teacher("schildt","java");
 System.out.println(t.name);
System.out.println(t.sub);
}
}
