How do I convert from int to String?

Question

I\'m working on a project where all conversions from int to String are done like this:

int i = 5;
String strI = \"\" + i;


        

Answer 1

There are three ways of converting to Strings

1. String string = "" + i;
2. String string = String.valueOf(i);
3. String string = Integer.toString(i);

Answer 2

The other way I am aware of is from the Integer class:

Integer.toString(int n);
Integer.toString(int n, int radix);

A concrete example (though I wouldn't think you need any):

String five = Integer.toString(5); // returns "5"

It also works for other primitive types, for instance Double.toString.
