public static void main(String args[]) {

String hexa_Input;

Scanner scan = new Scanner(System.in);

System.out.print("Enter Hexadecimal Number : ");

dec_output = getHexaToDec(hexa_Input);

Pass the string to the getHexaToDec function

and it returns the decimal form in the variable dec_output.

System.out.println("Number in Decimal: " + dec_output);

scan.close();
