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:
======================================
hrms.java:22: error: cannot find symbol
hrmsModel HRMSModel = new hrmsModel();
^
symbol: class hrmsModel
location: class HRMS
hrms.java:22: error: cannot find symbol
hrmsModel HRMSModel = new hrmsModel();
^
symbol: class hrmsModel
location: class HRMS
hrms.java:24: error: cannot find symbol
hrmsView view = new hrmsView(HRMSModel);
^
symbol: class hrmsView
location: class HRMS
hrms.java:24: error: cannot find symbol
hrmsView view = new hrmsView(HRMSModel);
^
symbol: class hrmsView
location: class HRMS
4 errors
=======================================
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.

I have attached a photo of my code and the error that I am receiving. There isn't the red underline so I am not sure why it cannot find the package.

I am using java 14.
How can I solve this error?
I am working with JOGL and it stopped working completely.
These are the errors i get:
Texture01.java:27: error: cannot access WriteCloneable
canvas = new GLCanvas(glcapabilities);
^
class file for com.jogamp.common.type.WriteCloneable not found
.\Texture01_GLEventListener.java:2: error: package com.jogamp.common.nio does not exist

IntBuffer ib = Buffers.newDirectIntBuffer(indices);
^

location: class Texture01_GLEventListener
4 errors
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!
I am trying to make Sublime work with Java. I know there is a lot of tutorials but all of them for Windows. I was going through this one but it is for processing and it doesn't work wit imports. http://blog.boreal-kiss.net/2012/10/27/processing-with-sublime-text-2/
I am just starting with Java and using ACMStarterProject with acm.jar.
http://www.stanford.edu/class/archive/cs/cs106a/cs106a.1124/assignments.html
What I want:
use sublime to build and run
use imports and package libraries
use java 7
I think I need to write a skript and make some changes to JavaC.sublime-build?
Thanks
Here is what I get in console:

does anybody know why am I getting these errors ?
Seems like you are missing the commons-math3 library.
