Java convert a HEX String to a BigInt

Question

Hi am trying to convert a hex string such as String hexStr = "1b0ee1e3"; to a bigInt, ideally i'd like to convert hexStr to a bigint in its decimal form,

I can convert a string to a bigInt w/o issues but when the string contains hex values i run into problems

Answer 1

Have you tried:

BigInteger bigInt = new BigInteger(hexString, 16); 

For example:

import java.math.*;  public class Test {     public static void main(String[] args) {         String hexStr = "1b0ee1e3";         BigInteger bigInt = new BigInteger(hexStr, 16);         System.out.println(bigInt); // Prints 453960163     } }
