Converting hexadecimal to decimal in JAVA

This is really as simple as it is.

import java.io.*; import java.lang.*; public class HexadecimalToDecimal{ public static void main(String[] args) throws IOException{ BufferedReader bf = new BufferedReader(new InputStreamReader(System.in)); System.out.println("Enter the Hexadecimal number:"); String str= bf.readLine(); int i= Integer.parseInt(str,16); System.out.println("Decimal:="+ i); } }
