Create New Java Class in Eclipse

In the previous lessons, we learned how to create new Java project and Java package in Eclipse. Here, we will learn how to create new Java class. A class in Java is a blueprint to held data in the form of  variables and member functions. For creating a new Java class, you need to first create a Java project.

Launce Eclipse and go to the File Menu, then

File > New > Class

Reach Eclipse New Class section

After clicking class above, a new dialog box opens up. It is the wizard to create new Java class in Eclipse.

Mention the package to contain the new class. Add the package name or select one by clicking Browser.

Enclosing type
Choose a type to enclose the new class. Select this or the above Package option.

Here, type the name of the Java class.

Access modifiers such as public, private, protected, abstract, etc. Here, select one of more access modifiers for the new Java class you’re adding.

Add a superclass for this class.

Add interfaces by clicking Add. These interfaces are the one, which the new class implements.

Which method stubs would you like to create?
Select the method stubs to create in this new class:

  • public static void main(String [] args): A main method stub to the new class.
  • Constructors from superclass: On selecting this, it copies the constructors from the new class’s superclass. Adds these stubs to the new class.
  • Inherited abstract methods: It adds to the new class stubs of any abstract methods
    from superclass.
  • Do you want to add comments? The wizard adds comments to the new class, if this option is selected.

The name of our project is StudyopediaProject, which we created before. We added a new package in it i.e. com.studyopedia.

Now, we’re adding a new Java class, with name Products. You can give any name to it.  After clicking Finish above, the Java class gets created successfully as shown below,

We have till now created project, package and class in Eclipse. The project name is StudyopediaApplication and the package is com.studyopedia. The class we added in this lesson is Products.

Let us now see a video describing how to create a Java class in Eclipse with step-by-step implementation,
