How can I cast Integer to String in Scala?

I searched for a while the answer to this question but came out empty. What is the simple command of casting variable X which is Integer, to a String?

Solution 1:

If you have variable x of type Int, you can call toString on it to get its string representation.

val x = 42
x.toString // gives "42"

That gives you the string. Of course, you can use toString on any Scala "thing"--I'm avoiding the loaded object word.

Solution 2:

Is it simple enough?

scala> val foo = 1
foo: Int = 1

scala> foo.toString
res0: String = 1

scala> val bar: java.lang.Integer = 2
bar: Integer = 2

scala> bar.toString
res1: String = 2

Solution 3:

An exotic usage of the s String interpolator for code golfers:

val i = 42
s"$i"
// String = 42
