![]() ![]() We can also write our Scala toInt method and Try, Sucess, and Failure.Įxample Code: import scala.util. The function toInt returns Some(Int) if the string can be converted (like if the input is "1234") else, it returns None if it is not possible to convert it to an integer. Let’s have another example of converting a string to an integer using Option. The function toInt returns the correct value if the string can be converted (like if the input is "1234") else, it returns 0 if it is not possible to convert (like if the input is "scala"). This situation normally arises whenever we receive data from user input via textfield or textarea, data is obtained as string and we required to convert string to int. This next code snippet is a more Java-like way of converting a string to an integer and handling the exception. Usually String to int conversion is required when we need to do some mathematical operations in the string variable that contains numbers. So we have to handle this exception using a try-catch block. ![]() Output: : For input string: "scala"Īt java.base/(NumberFormatException.java:67) We used the toInt method to cast the string "1234" to an integer, but the issue with the above code is that if the string is not a pure integer, we will get NumberFormatException just like in the following example output. In Scala, if we want to convert a String to an Integer, we can use the toInt method.
