This method takes two arguments, one of type String and another of type int. This method returns a Byte object holding the value extracted from the specified String when parsed with the radix given by the second argument. The first argument is interpreted as representing a signed byte in the radix specified by the second argument.

Parameters: Two parameters are required for this method.

Java

public class BytevalueOfRadix {
    public static void main(String[] args) {

        String s = "101001";
        int radix = 2;
        System.out.println(Byte.valueOf(s, radix));
    }
}
