The hex string is also known as Hexadecimal Number String is a number created using hexadecimal number system i.e. base 16 number system.

Integer in Scala is a numerical value that uses base 10 values.

## Scala – Converting Hex String to Int

A hexadecimal string can be converted to integer type using the parseInt() method of the Integer class that will parse the given string with a given base to an integer value.

### Syntax

```    val int_value = Integer.parseInt(hex_string , base)
```

## 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.
