# class Java Keyword

The class keyword is used to declare a new Java class, which is a collection of related variables and/or methods.

Classes are the basic building blocks of object-oriented programming. A class typically represents some real-world entity such as a geometric Shape or a Person. A class is a template for an object. Every object is an instance of a class.

To use a class, you instantiate an object of the class, typically with the new operator, then call the classes methods to access the features of the class.

## Examples

      public class Rectangle
      {
         float width;
         float height;

         public Rectangle(float w, float h)
         {
           width = w;
           height = h;
         }

         public float getWidth()
         {
            return width;
         }

         public float getHeight()
         {
            return height;
         }
      }
