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?

We can convert int to String in java using String. valueOf() and Integer. toString() methods.
The toString() method is utilized to return the string representation of the specified value. Method Definition: def toString(): String. Return Type: It returns the string representation of the specified value. Example #1: // Scala program of Int toString()
Scala some class returns some value if the object is not null, it is the child class of option. Basically, the option is a data structure which means it can return some value or None. The option has two cases with it, None and Some. We can use this with the collection.
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.

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 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
