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;
     }
  }
