problem in java programming Posted: 27 Sep 2010 09:33 AM PDT Quote: 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().
