  }
}

Definition and Usage

The keyword “class” is employed to define a class.

All Java code execution occurs within a class, which should begin with an uppercase letter and have a file name matching the class name.

A class functions similarly to an object constructor. Refer to the example below to observe its utilization in object creation.
