    A constructor can never return a value, it hasn't got any return type.

    Correct gaurav constructor can never return any valu.
    like this

    public class r
    {
    int p;
    public void r(int k)//Show an error because here constructor should return a valu that is "0"(void);
    {
    p=k;
    System.out.println("p= "+p);
    }
    public static void main(String args[])
    {
    r t=new r(5);
    }
    }

    I answered with reference to C++, not sure about other OO languages though.

    hello everyone,
    System.out.println("the value of c is="+c);
    as we know here that here +sign appends the value of c to the string which preceids it i.e if the value of c is in the form of integer the firstly it is being converted to string.why is it so??
    can anyone please justify that for me????

    @anand here in java "+" is an operator which is used to add or concatenate two strings objects that's why c is converted to string.

    You fellas are much more up to date with this stuff than me, but thinking back to Pascal...
    p = ^t;
    t = type
    constructor init;
    destructor done; virtual;
    end; {type}
    if new(p,init()) <> nil then...

    So, I think the constructor returns a pointer if successful and nil when not.

    Any better ideas?
