Java - Convert integer to string

Question

Given a number:

int number = 1234;

Which would be the "best" way to convert this to a string:

String stringNumber = "1234";

Answer 1

There are various ways:

• String.valueOf(number) (my choice)
• "" + number (I don't understand how the compiler manages it, possibly it is as useful as the above)
• Integer.toString(number)
