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.*.

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...
I am trying to import java.util.logging into my class but it doesn't exist.
I am using Netbeans 8.2 installed just a few weeks ago, when I started learning Java and Netbeans.
I found this old bug report Bugzilla report but this is so old, I would expect it to be fixed, especially for a logging function.
The following is the only code I have in the class file. The 2 java.awt classes import OK. I added those just to prove that I had access to the standard Java library. The auto suggest does not suggest anything starting with log...
package myflag.flag.logging;
import java.util.logging;
import java.awt.Color;
import java.awt.Font;
Any ideas please???
Only a type can be imported. java.util.logging is a package. Please specify directly what class you need to import or you can import like this for all class inside this package: import java.util.logging.*;
I used a newer class to substitute a deprecated one. The class is MultiPartEntityBuilder. When i wrote it in the code, the compiler suggested me to import the following package
import org.apache.http.entity.mime.MultipartEntityBuilder;
I have imported it. But the compiler cannot still find it, giving me the error on the title
MultiPartEntityBuilder cannot be resolved to a type
So, it sounds quite strange to me. I've already succesfully imported similar packages
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.entity.mime.content.ContentBody;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;
Does it mean i have an old version which doesn't define any class named MultiPartEntityBuilder ?
How does the compiler know that i should import that class, part of that package, if he got an old version of that package?
Please note that
import org.apache.http.entity.mime.MultipartEntityBuilder;
is market as an error.
Upload Apache HttpClient Mime 4.3.1 jar file http://mvnrepository.com/artifact/org.apache.httpcomponents/httpmime/4.3.1
It means that org.apache.http.entity.mime.MultipartEntityBuilder isn't accessible during compilation time. You should add it to your project somehow depends on your build tool.
Looks like a spelling error, you had MultiPartEntityBuilder instead of MultipartEntityBuilder. The "P" shouldn't be capitalised.
Hi I am writing a test using UIAutomator API , however in my java project I want to import the com.android.camera package.
However I am always getting an error that this import cannot be resolved.
I have added the android.jar in my build path and rest of the things work fine.
However I am not able to import this package.
There is no such package in android, maybe you are looking for
com.android.hardware.Camera
class ?
if so try
import com.android.hardware.Camera;
The camera class resides inside the below package so try to import below package instead of com.android.camera add the below.
import android.hardware.Camera;
import android.hardware.Camera;
try to place it after your package name
If you are using Eclipse than just press Ctrl + Shift + O Eclipse will automatically add the required libraries in your source code. If still you are getting import issue than you need to check if you are using correct API or the spelling is correct.
I am using a code sample that suppose to be working, but I keep get an error with those 3 import statement.
import com.amazonaws.services.s3.transfer.internal.MultipartUploadCallable;
import com.amazonaws.services.s3.transfer.internal.PutObjectCallable;
import com.amazonaws.services.s3.transfer.internal.TransferStateUpdatingCallable;
the error message says : The import com.amazonaws.services.s3.transfer.internal.MultipartUploadCallable cannot be resolved
why is that happening and how can I solve it ?
Please add jars that contain this classes. This will always solve your problem.
This means that implementations of referenced classes cannot be found in classpath. Since you are using amazonaws you should add appropriate library to your project's dependencies.
