How to check if a string contains only letters and numbers using RegEx in Scala

Answer 1

object AlphanumericChecker {
  def isAlphanumeric(str: String): Boolean = {
    // Define the regular expression for alphanumeric characters
    val alphanumericRegex = "^[a-zA-Z0-9]+$"

    // Use the matches method to check if the string matches the pattern
    str.matches(alphanumericRegex)
  }

  def main(args: Array[String]): Unit = {
    val str = "VuZ3q7J4wo35Pi"

    if (isAlphanumeric(str)) {
      println("The string contains only letters and numbers.")
    } else {
      println("The string contains characters other than letters and numbers.")
    }
  }
}

  
     
/*
run:
  
The string contains only letters and numbers.
