Converting an integer to a string is a very common programming task. The most popular method for doing this are to use either String.valueOf(int) or Integer.toString(). Which one is better and why?
Take a look at the implementation of String.valueOf:
String valueOf(int i){return Integer.toString(i, 10);}
Note that additional method call? Using Integer.toString() directly can avoid this, which can be very effective if your application performs this type of conversion in long loops.
Conclusion? Integer.toString() is the better method.
