How to implement com.objectspace.jgl package? - java

I downloaded a code from internet which uses the following code
import com.objectspace.jgl.*;
import com.objectspace.jgl.Array;
import com.objectspace.jgl.algorithms.Shuffling;
import com.objectspace.jgl.algorithms.Sorting;
import com.objectspace.jgl.BinaryPredicate;
I have searched on internet but I am unable to find the jgl package.
If anyone can help me find the package or the methods included in those packages, it would be of great help. any help is greatly appreciated. Thanks.

Not finding import Utils.*;

i want to import the following:
import Utils.*;
It Simply does not find that and i have no Plan how to solve that. Can you help me?

UPDATE:
I needed to import a external .jar File into the classpath. After doöing this, my code worked without any issues and i could continue programming :)

Try import java.util.*;. Looks like you have the incorrect package name. Though this is guessing what package you are trying to import based on a single word...

Media won't instantiate despite correct import packages in java

my Media object does not want to instantiate and i have all the correct imported jar files including JavaFX so that I can play mp3 files.
I have the imported packages:
import javax.media.*
import com.sun.media.MediaPlayer;
import com.sun.media.codec.audio.mp3.*
import javax.print.attribute.standard.Media;
But it still doesn't run. Any suggestions would be appreciated as i've been googling everyting about media and plugins for days now :(

You must import this packages:
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
Here is example of mp3 player.

You have to delete com.sun.media.mediaPlayer;
I had the same problem just now xD. Hope this helps.

Import issue in Eclipse

I have the following import in my java code in an eclipse project
import org.jscience.*;
However upon writing the code
Real r1 = new Real.valueOf(1);
I receive the error
Real cannot be resolved to a type
I am puzzled as to why this is happening as I am correctly importing (or so I believe)
Also to note, eclipse suggests using
import org.jscience.mathematics.number.Real;
But I am trying to avoid using the import for the full class location within the Jar.
Any ideas?
Thanks in advance
Martin

Try
import org.jscience.mathematics.number.*;
Because
import org.jscience.*;
will actually only import classes from within the jscience package and not any subpackages.

If we suppose your import is not throwing errors, try importing g.jscience.mathematics.number.*.

Which version of Netty API does this example code use? Unable to resolve io.netty.handler.codec.http.DiskFileUpload with 3.2.x

I came across this sample code for handling file uploads with Netty, this looks perfect, just what I needed. Unfortunately I am having difficulty incorporating this class as many Netty API features are unresolved. One of them for example is io.netty.handler.codec.http.DiskFileUpload, I am unable to find this in any of the online API docs for 3.0,3.1.3.2.
The class I am having issues with is here:
https://github.com/netty/netty/blob/master/example/src/main/java/io/netty/example/http/upload/HttpUploadServerHandler.java
I have tried using netty-3.2.5.final, 3.3.1.final, 3.4.0.Alpha
Unresolved imports:
import org.jboss.netty.handler.codec.http.HttpPostRequestDecoder.EndOfDataDecoderException;
import org.jboss.netty.handler.codec.http.HttpPostRequestDecoder.ErrorDataDecoderException;
import org.jboss.netty.handler.codec.http.HttpPostRequestDecoder.IncompatibleDataDecoderException;
import org.jboss.netty.handler.codec.http.HttpPostRequestDecoder.NotEnoughDataDecoderException;
import org.jboss.netty.handler.codec.http.InterfaceHttpData;
import org.jboss.netty.handler.codec.http.InterfaceHttpData.HttpDataType
import org.jboss.netty.handler.codec.http.HttpDataFactory;
import org.jboss.netty.handler.codec.http.DiskAttribute;
import org.jboss.netty.handler.codec.http.DiskFileUpload;
import org.jboss.netty.handler.codec.http.FileUpload;
import org.jboss.netty.handler.codec.http.DefaultHttpDataFactory;
import org.jboss.netty.handler.codec.http.Attribute
Any help appricated

When you see the org.jboss.netty namespace, that indicates v3.x
io.netty is used in v4.
Online documentation is located at http://netty.io/docs/

It's under master branch which is 4.0.0.Alpha1-SNAPSHOT from the pom.
