Program to convert hex string to long in Scala

object MyObject {
    def main(args: Array[String]) {
        val hexString : String = "42e576f7"
        println("The Hex String is " + hexString)
        val intVal : Int = Integer.parseInt(hexString, 16)
        val longInt  = intVal.toLong
        println("HexString to Long value : " + longInt)
    }
}

Output:

The Hex String is 42e576f7
HexString to Long value : 1122334455

Explanation:

In the above code, we have created a hexadecimal string named hexString. Then we have converted hexString to integer value using the parseInt() method of the Integer class and store it to intVal. This intVal is converted to a Long Integer value using the toLong method and prints the value using println method.
