Class Keyword in Java

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;
}
}
