What is the exact difference between out.write() and out.print()

Question

In my servlet I gave both out.print and out.write. but both prints in the browser.

What is the exact difference between these two and when

Answer 1

The basic difference is that out.write() explodes if you pass it a null:

String s = null;
out.print(s); // outputs the text "null"
out.write(s); // NullPointerException
