https://www.testingdocs.com/create-a-new-java-project-in-eclipse/
New Java class
Launch the Eclipse IDE. Right click on the project in the Package Explorer and choose New ->> Class.
This will launch a a New Java Class Wizard. We can set multiple things in this wizard screen. Some are optional as well.
Specify the package name for the class in the Name: textbox. If we don’t specify the package name the class would created in the default package under the src directory. This is not recommended.
Enter the name of the class. We need to follow naming conventions to name the Java class and package. For example, it is discouraged to have a class name that begins with a digit.
Superclass
We can also specify the parent class for the current class in Superclass textbox. The default value is the java.lang.Object class. We can have only one class as the Superclass in Java. Java doesn’t support multiple class inheritance.
We can add Interfaces to the class. Click on the Add… button and choose the Interface. A class can implement multiple interfaces.
To add the main method to the class, check the main method checkbox.
public static void main(String[] args)
This method will allow you to run the Java application.
To generate comments check the Generate comments checkbox.
Click on the Finish button.
The class would be created and added to the project. The Workbench will update itself with the newly created class.
