In Scala, there is a huge library to support different operations on a string. One such operation is to convert string to int in Scala.

A string can be converted to integer in Scala using the toInt method.

Syntax:

    string.toInt

This will return the integer conversion of the string. If the string does not contain an integer it will throw an exception with will be NumberFormatException.

So, the statement: val i = "Hello".toInt will throw an exception instead of an integer.

So, we need to handle this exception and we will do this using the try-catch block and print "The string in not integer" when the string to be converted does not contain an integer value.
