I want to add a sentence to all new classes that I create in java. By default Java entry point comes like this: 

public static void main(String[] args) {

}

and I want to achive something like this:

public static void main(String[] args) {
Scanner key = new Scanner(System.in); 
}

Is this possible? Thank you!

Sure. How you do it depends on your IDE, though, which you haven't mentioned here. - azurefrog
Java does not create classes. You are free to create new files however you like. - SLaks
This is the entry point, not the constructor. You can change the body of this method, but not the name and parameters. - Andrew Williamson
@SLaks Well, IDEs like eclipse have a wizard that will generate a class based on a template you configure. You could set that to have whatever base code and comments you like. - azurefrog
main() is not a constructor, it's a method that will be executed when running your programme. - Youssef NAIT

In Eclipse it is possible to edit built-in code templates (the one used by Eclipse e.g. for new class files) and create your own named snippets (for fast access to often-reused templates).

Code Templates

Go to Window > Preferences > Java > Code Style > Code Templates, then to Code > New Java files. Adapt this or some other template to suit your needs.

Templates

Usually it's better though to add a smaller template via Window > Preferences > Java > Editor > Templates and use it wherever you need. Smaller bricks are more reusable then hardcoded class templates. Those are applied with <type-beginning-of-template-name + ctrl + space.
