Eclipse cannot import import com.google.maps.* (For java Fx programme)

I am working on a Java fx application and I need to import some libraries from com.google.maps.
I imported these libraries :
import com.google.maps.GeoApiContext;
import com.google.maps.PlaceDetailsRequest;
import com.google.maps.PlacesApi;
import com.google.maps.QueryAutocompleteRequest;
import com.google.maps.errors.ApiException;
import com.google.maps.model.AddressComponent;
import com.google.maps.model.AddressComponentType;
import com.google.maps.model.AutocompletePrediction;
import com.google.maps.model.PlaceDetails;

The java import statement is a little bit misnamed, it really means alias. import com.google.maps.GeoApiContext; really just means: Any time you find the type GeoApiContext anywhere in this source file, assume I meant to write com.google.maps.GeoApiContext.
Crucially, it does not 'invoke' any code in that class whatsoever, nor does it find or download any dependencies from the internet for you.
You will need to find the jar(s) that provide these classes and put them on the classpath of this project.
It can be as simple as downloading the relevant jar (perhaps com.google.maps-google-maps-services.jar?), put it in a lib dir someplace inside this project, finding that in the package explorer, right clicking it, and selecting 'add to classpath'.
Or, more likely, you want to use gradle or maven to take care of this for you: These tools turn simply mentioning the dependency in a list of libraries you require into automatically finding that on the internet, downloading it, configuring your IDE so that it knows where it is, and using that dependency during build and run steps.

How to import correct package for StdDraw?

I want to use the StdDraw package, and I've tried many different ways of importing it.
Of course I tried:
import StdDraw;
But, when I look at the documentation from Princeton here, it shows that StdDraw is part of Objects, so I try this:
import java.lang.Object.StdDraw;
However, this results in an error:
error: cannot find symbol in
import java.lang.Object.StdDraw;
I saw this question here but it does not answer this question either.
How do I import StdDraw? thank you.

if you want to use StdDraw you must have
either the sources
or the classes (best zipped up as jar)
as preferred way you use the sources (see http://introcs.cs.princeton.edu/java/15inout/). it says there "To use these libraries, download StdIn.java, StdOut.java, StdDraw.java, and StdAudio.java into the same directory as your program. "
once you did this the imports should be working.
NOTE: all four files are not in packages, so you should 'download' them into the 'standard' package. That means you have to download them to the root package of your project.
by the way: don't import import java.lang.Object.StdDraw; but do just import import StdDraw;

First of all check encoding of your IDE. It should be set to UTF-8. It is important if you are using MS Windows operating system.
Then create StdDraw.java class in the same package as the package of your program you are writing. Remove class declaration, leave only package declaration.
Then visit this page: https://introcs.cs.princeton.edu/java/stdlib/StdDraw.java .
Copy all its contents (Ctr-A, Ctrl-C) and then paste it into StdDraw.java file you created previously.
StdDraw.java has its own main method so try to run it in order to check that the library works correctly. You should see a window with four strange figures :) .
Don't touch StdDraw.java anymore. Now you can easily import StdDraw library and refer to its methods with name of the class.
Enjoy

Why don't I need to use the import keyword when importing a library?

I imported an external JAR to my project in Eclipse, by following these instructions:
Right click on the project > Build Path > Add external archives > Choosing the JAR file from the hard drive.
The JAR file than appears in the 'References libraries' section in my project, and works fine.
However, I never need to use the import keyword in my classes in order to use the classes from the JAR. I find this weird, I thought I'd have to use import myImportedJar or something similar for this to work.
Is it normal that I don't have to use the import keyword? Did I do something wrong?

The import statement is used to be able to refer to types and their members by their simple names. You don't need to import classes that are in the same package, unless they are nested members of other classes. This is true regardless of where the class comes from, for example, if it's in another .jar.

The import keyword works on a package level. If these packages are supplied by jars or not is not a feature of the java programming language.
import only makes a name available in unqualified form in your program. The following code fragments are identical:
java.util.List<Object> list = new java.util.ArrayList<>()
vs
import java.util.List;
import java.util.ArrayList;
List<Object> list = new ArrayList<>()
Now, importing a jar file in eclipse puts the classes from this jarfile on the classpath - the total "world" of available classes for your application.

How to import my java class into another java class in Xpages java

In my Xpage, I have added to Java classes. One is "AUser" declared in Models package and one is "AUserRepository" declared in a Repository package.
When I try and import AUser into a class in my AUserRepository... the import statement I type in is not working.
import com.Discussion.utils.AUser;
Weird thing is, If I exit out of Notes and load up eclipse standalone, and make the same kind of stuff, the import works fine. Am I missing out some important factor in Xpages?
The problem definitely is the import routing.

import Models.AUser;
import Repository.AUserRepository;

Is the project build path correct? Project - Properties - Java build path. Also, have you tried cleaning the project? Project - Clean....

Java JAR application: how does the structure look like? (Eclipse)

I'm a seasoned PHP programmer with backgrounds within Powershell, JavaScript etc.
I see the benefits with Java and wish to dig deeper.
All the documentation though is too advanced for me atm.
A typical PHP structure:
index.php
classes/class_get.php
classes/class_set.php
Where in index.php you would have the lines
require_once "classes/class_get.php";
require_once "classes/class_set.php";
Now in Java...
I understand Windows files are in .JAR format. No problem here, easy to understand.
I am confused when creating this in eclipse. Is the strucutre;
Main.java
src*/defaultPackage**/myClass.java
* folder
** package
Where in the Main.java file you would declare "import myClass.java"?
Also other packages such as the following:
import java.awt.*;
import java.awt.event.*;
import java.net.URL;
import javax.swing.*;
I am getting errors, and this manifest file, I haven't heard of it in any tutorials yet?

Try this, this is the way to create a jar or runnable jar in eclipse
File -> Export-> Java ->Runnbale JAR file
Launch configuration : your Class containing the public static void main(String[] args)
Export destination : Target place
Library Handling:
Package required libraries into generated JAR
FINISH

a) There are no Windows files in Java. Java is cross platform.
b) Something with a slash delimiter is always a folder. Something with a dot is always a package. Don't confuse them, because it is confusing enough.
c) Don't use the term "defaulPackage", because there is such a term for the case, that you don't specify any package. Then the package of your class is called the default package.
Main.java
src*/defaultPackage**/myClass.java
Where in the Main.java file you would declare "import myClass.java"?
You never import something .java, because you import a class, not a source file. Often you only have third party compiled classes in a jar, and don't have the source. Well - maybe.
If your class belongs to a package, the name of the class is the whole package name. You can omit it from classes in the same package.
So we don't know whether Main and MyClass (use Upper case, if you like to communicate with others - else you're confusing us) belong to the same package.
If so: Don't import anything.
Else: Import the whole package name, which might contain multiple dots.
So for example:
import yourCompany.games.monstersahead.*;
or
import yourCompany.games.monstersahead.MyClass;
for example.
The package name will usually not contain folder names like src, bin, classes.
