As a result of compilation of the program gave out an error
/partrain/src/ParallelTraining.java:309: error: cannot find symbol
Array array = contonewdatabase.createArrayOf("string", residualgroupparam);
^
symbol: class Array
location: class Reduce
I suspect that didn't connect necessary library. Prompt that it is necessary to connect.
I suspect you're looking for the createArrayOf method from the Connection class in the java.sql. In that case, you forgot the import:
import java.sql.Array

wallpaper_manager: any
When I add the package, the project gives an error.
There was no problem in the old versions of flutter, but the application does not work anymore, how should I proceed?
If you look at the current javadocs for FlutterLoader, it doesn't declare a getInstance() method anymore. The method was deprecated and then removed.
According to https://stackoverflow.com/a/64456438/139985, since Flutter 1.22 you need to get hold of a FlutterLoader instance using FlutterInjector:
import io.flutter.FlutterInjector;
...
FlutterLoader loader = FlutterInjector.instance().flutterLoader();

You should check your project's gauge.log. The Traceback is in the file, that will help you.

I am working with JOGL and it stopped working completely.
These are the errors i get:

The Path and Classpath variables are correct, I reinstalled JDK and JOGL2 but still get an error with WriteClonable and com.jogamp.common.nio.*
Any help is appreciated!
Sorry, I'm sure this is some rookie istake I'm making but I have a MVC pattern package which keeps returning this errors to me:

=======================================
Would really appreciate if you could tell me what I was doing wrongly here...Thanks in advance! I've added the code for the main package of my class hrms MVC gui below, for your reference.
hrmsModel HRMSModel = new hrmsModel();
seems like its not arrange properly.
I think the right arrarangement is this YourClass yourVariable = new YourClass()
First, check if you have the classes hrmsModel and hrmsView in the same package as HRMS. If you don't have them, you should import them.
On a side note, it's best if you follow the Java naming convention and name your class HRMSModel and your variable hrmsModel. If you are following that convention, then you might be confusing the order of both and that's why the compiler complains.
Syntax for object creation is:
ClassName instanceName = new ClassName();
So change this
hrmsModel HRMSModel = new hrmsModel();
to:
HRMSModel hrmsModel = new HRMSModel();
Under hrms package you have HRMS* java, but you are trying to create object for hrms* classes.
Change name and execute.
Already import the weakreference but the compiler cannot find the symbol, what wrong? There a memory leak in DumpReceiver.java I thought weakreference might free after used?
import java.lang.ref.WeakReference;
Receiver r = new DumpReceiver(System.out);
WeakReference<Receiver> wr = new WeakReference<DumpReceiver>(r);
MidiInDump.java:64: cannot find symbol
symbol : constructor WeakReference(javax.sound.midi.Receiver)
location: class java.lang.ref.WeakReference<DumpReceiver>
WeakReference<Receiver> wr = new WeakReference<DumpReceiver>(r);
^
Look closely at the error message. It's not talking about the class (it's finding that just fine). It is talking about the constructor. It doesn't find a constructor that takes a javax.sound.midi.Receiver argument on the type WeakReference<DumpReceiver>. Looking at the JavaDoc of WeakReference<T> there is one constructor that takes an argument of type T.
You're trying to create a WeakReference<DumpReceiver> but try to pass in an object of type javax.sound.midi.Receiver. You either need to create a WeakReference<Receiver> instead or change the variable r to be of type DumpReceiver.
