Program to convert hex string to int in Scala

object MyObject {
    def convertHexStringToInt(hexString : String): Int = {
        return Integer.parseInt(hexString, 16)
    }
    
    def main(args: Array[String]) {
        val hexString : String = "10DEA"
        println("The Hex String is " + hexString)
        println("The String converted to decimal is " + convertHexStringToInt(hexString))
    }
}

Output:

The Hex String is 10DEA
The String converted to decimal is 69098

Explanation:

In the above code, we have created a function convertHexStringToInt() which will convert the given hex String to an int. The convert uses the parseInt() method which is available in the Integer class. The function takes a string as a parameter and returns the integer which is string conversion of hexString. This returned value is printed using the println method.
