如何在Netbeans中创建和导入库-完整记录的Q

Question

It's me again. So here's the deal, I still don't really grasp if I am doing something wrong.

I am trying to create my own Personal Library, in which I have certain string methods and so on.

I've started by creating a new Project as a Java library:

Then I've added a package to that library:

After that I've created a class in said package:

Here the code of my class:

And cleaned and built that Class//Library. Run -> Clean and Build
And afterwards created the JavaDoc Run -> Generate JavaDoc(MyTestLibrary)

After doing this i decided to add my newly created Library to the Libraries under Tools - > Libraries :

After that I've added a new Library (bottom right) and named it TestLibrary:

SO decided to add the .jar File first. I clicked on the “Add JAR/Folder... ” Option and searched for my Projekt Folder (from MyTestLibrary) and went in to the “dist” folder and selected the .jar file:

After that I've added the “src”-Folder in “Sources” and the “javadoc”-Folder in “Javadoc”.

After i was finished it was time to create a new Project, to be precise a new Java Application, and try to import my freshly created library. I rightclicked on Libraries and clicked on “Add Library...”:

And imported my Test Library and adding it:

Happy that I've added my Library to my application I decided to import it import TestPackage.TestClass; .

If I try

public static void main(String[] args) 
{
    TestClass.
}

The only suggestion is TestClass.class and not TestClass.TestMethod .

Why can't I access the methods of the “TestClass” directly?

How can I see them?

I've tried being as specific as possible. I hope this time I can fully understand what is going on and why I can't access them.

Answer 1

The solution was fairly simple and obvious.

To access the methods without the need of creating an instance of the class i just had to declare them static .
