Nasser: This is absolutely correct about Ada, and a helpful point of 
reference in Java; see also the static member functions of class String.

For more control over width and base, instantiate Integer_IO:

package Ada.Integer_Text_IO is new Ada.Text_IO.Integer_IO (Integer);

An instance of which may already exist in one's library:

with Ada.Integer_Text_IO;

You might also like to compare these two projects that implement the 
same root finding algorithm and test program in Ada and Java:
