Convert a string representation of a hex dump to a byte array using Java?

I am looking for a way to convert a long string (from a dump), that represents hex values into a byte array.

I couldn't have phrased it better than the person that posted the same question here:

http://www.experts-exchange.com/Programming/Programming_Languages/Java/Q_21062554.html

But to keep it original, I'll phrase it my own way: suppose I have a string "00A0BF" that I would like interpreted as the byte[] {0x00,0xA0,0xBf} what should I do?

I am a Java novice and ended up using BigInteger and watching out for leading hex zeros. But I think it is ugly and I am sure I am missing something simple...

How do I resolve this?

Dumping a java object's properties

Is there a library that will recursively dump/print an objects properties? I'm looking for something similar to the console.dir() function in Firebug.

I'm aware of the commons-lang ReflectionToStringBuilder but it does not recurse into an object. I.e., if I run the following:

public class ToString {

    public static void main(String [] args) {
        System.out.println(ReflectionToStringBuilder.toString(new Outer(), ToStringStyle.MULTI_LINE_STYLE));
    }

    private static class Outer {
        private int intValue = 5;
        private Inner innerValue = new Inner();
    }

    private static class Inner {
        private String stringValue = "foo";
    }
}

I receive:

ToString$Outer@1b67f74[ intValue=5
innerValue=ToString$Inner@530daa ]

I realize that in my example, I could have overriden the toString() method for Inner but in the real world, I'm dealing with external objects that I can't modify.

How to dump data stored in objective-c object (NSArray or NSDictionary)

Forgive me for a potentially silly question here, but in other programming languages (scripting ones like PHP or Perl) it is often easy to dump everything contained within a variable.

For instance, in PHP there are the var_dump() or print_r() functions. Perl has the Data::Dumper CPAN class, etc etc.

Is there something like this for Objective-C? It would be very convenient in a few cases to be able to dump everything like that, instead of using gdb to inspect each variable.

How can I convert an MDB (Access) file to MySQL (or plain SQL file)?

Is it possible to create a Dump of SQL commands from a Microsoft Access database? I hope to convert this MDB file into a MySQL database for importing so I don't have to go through the CSV step.

I would expect even an MSSQL dump file to still contain workable SQL commands, but I know nothing of MSSQL, please let me know.

Transfer Mysql database to another computer [closed]

I have a mysql database filled up and running on a windows computer, is there any tool to transfer the database to another computer (running ubuntu)?

Else I'll just write a script to take all the data base into SQL and insert it on the other computer. Just trying to save some time :)

Thank you all.

C# How to dump all variables & current values during runtime

Are there any in-built or 3rd party libraries that allow you to simply dump all variables in memory during run time? What I would like is to be able to view variables & current values similarly to viewing them by hitting a break point and hovering over variables, but without actually having to halt the program execution (i.e. just get a snapshot). Would be good if it could dump them to a file which can then be opened later in a program to get a nice GUI interface to view them, but simple text file dump would be good enough.
