class a
{ }

class c extends a
{
c(){System.out.println("class B");}
public void toString()
{
String g="hello";
System.out.println(g);

}

public static void main(String [] arg)
{
a d=new a();
System.out.println(d);

c y=new c();
//System.out.println(d);
System.out.println(y);

}
}
Here is my above program in which i am facing problem.
Here in the above program if we create an object of class a and simply print it then it shows a@1888759 as the output it means that it calls to String() from the Object class and returns the text representation of object of class a but i want to override toString() to print my own text i.e hello here but while executing it gives an error.
So how to override the toString().

    oh i got the answer
    here is my code.
    class a
    {

    }
    class c extends a
    {
    c(){System.out.println("class B");}
    public String toString()
    {
    String g="hello";
    //System.out.println(g);
    return g;
    }

    public static void main(String [] arg)
    {
    a d=new a();
    System.out.println(d);

    c y=new c();
    //System.out.println(d);
    System.out.println(y);

    }
    }
    i was just making silly mistake.
    Here i have to give the return type String and have to return the string.

    Hello CEans
    What is the difference between System.out.println() and System.out.write()???
