Q: How to convert hexadecimal String to int?

[Erik Hietbrink]

Hi

Can anyone tell me how i convert a String filled with a hexadecimal
number to an integer? I'm sure there is a standard function for that
but I cant find it. Help!

Email answer plz to e...@sci.kun.nl

Greetx, Erik

You can use Integer.parseInt() like this:

int iDecimalValue = Integer.parseInt( "3E8", 16 );

To go the other way, you can do this:
String hex = Integer.toHexString( 1000 );

For this and the 255 other similar conversion questions, see "conversion"
in the Java glossary. There a table showing you how to convert anything to
anything including your hex String to int.. There is also a program called
the Java Amanuensis that will generate code for you that you can cut/paste.

Standard? ---> Sorry, but you need to convert the hexadecimal to
decimal, base 10, if you want parseInt to work for you (there is no
parseDouble). Other than that, you're on your own.

- good luck

I really wish people wouldn't respond unless they knew what they were
talking about.

Yes, there *IS* a standard way to convert a Hexidecimal string and nothing
in the question had anything to do with the Double class. Sheesh.

Try:

int intValue = Integer.parseInt(hexString, 16);

There are many more functions for such conversions described in the
JDK-1.1.6 online documentation under "java.lang.Integer".
