    Default How to import Hex class correctly?

    Hello

    I want to use this method Hex.decodeHex() in my class, but there is something wrong with import statement!!
    I wrote : import org.apache.commons.codec.binary.Hex;

    Do you have the jar of the Apache Commons Codec library? If not, go to:
    Codec - Download Apache Commons Codec

    download one of the binaries bundle, unpack and then put "in classpath" the commons-codec-X.Y.jar. How to do this depends on how you are compiling/running, that is, if from command prompt (using JDK tools directly) or if from an IDE (Eclipse, etc...)

    thank you
    after unpacking the zip file, i found this jar file "commons-codec-1.9.jar", and i put it in the same class directory.
    I am using netbeans IDE, what is the next step, please?

    What do you mean?
    I don't use NetBeans so I don't know the exact procedure. Open your project properties, I am sure you will find a section/voice something like Libraries, Classpath, Build path or similar.
