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

There are three major differences:

1) If you try to print a null value of a String with out.write() , It will throw NullPointerException while out.print() will simply print NULL as a string.

 String name = null;
 out.write(name); // NullPointerException
 out.print(name); // 'Null' as text will be printed

2) out.print() can print Boolean values but out.write() can not.

boolean b = true;
out.write(b); // Compilation error
out.print(b); // 'true' will be printed 

3) If you are using out.write(), you simply can not place arithmetic operation code but out.print() provides the support.

out.write(10+20); // No output will be displayed.
out.print(10+20); // Output '30' will be displayed.
