Question

Given a number:

int number = 1234; 

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

String stringNumber = "1234";

^{I have tried searching (googling) for an answer but no many seemed "trustworthy".}

Answer 1

There are multiple ways:

• String.valueOf(number) (my preference)
• "" + number (I don't know how the compiler handles it, perhaps it is as efficient as the above)
• Integer.toString(number)

Answer 2

Integer class has static method toString() - you can use it:

int i = 1234; String str = Integer.toString(i); 

Returns a String object representing the specified integer. The argument is converted to signed decimal representation and returned as a string, exactly as if the argument and radix 10 were given as arguments to the toString(int, int) method.
