getWriter

What does it mean when its said getWriter() returns the printwriter object???...

Printwriter out =new Printwriter()
this also should create a printwriter object

then why this Printwriter out =response.getwriter()

And... response object can call get Writer method since it is inherited from servletResponse( interface).. tat means getwriter is abstract method..

so where is the implementation for getWriter() ...?

Welcome to the Ranch

Careful about spellings: getwriter() and getWriter() are different things.

If you use a get method, you obtain a reference to whatever that object already has as a field. So response.getWriter() will give you whichever Writer response is already using.

If you write new Writer(), however, you get a completely different Writer.

Thanks for replying

I understood.

But when is the first time response gets write object and who gives it? container?

Yes, the container. You don't want a new one, you want the one that will actually write to the response.

Moving to servlets forum.

I've a doubt regarding this. If we use two reference to refer this PrintWriter, what will happen? I used it, but the output is different, when we write using these two reference. Why is that?

Without knowing what you actually did, it's impossible to answer that question. If you have two references to the same object there will be no difference.

In a JSP page, I've used two references to refer the same PrintWriter object, with the use of getWriter() method. And, I used this two reference to write the output. But they aligned in different way.

You have Java code in your JSP?

I used it at the beginning level, not now. At that time, I've this experienced, that's why asked you!
