On the first day at Payilagam Institute, the participants were greeted with a warm and friendly atmosphere.As they settled in, the trainer, prithiviraj, began the session by discussing the class and object. first question we dicussing 
 //what is class? 
Class is a collection of object
*It doesn't take a any space on memory
*Class also called a blueprint
*If create a class name it's start from upper case only 
ex:
what is blueprint?
A single sheet of the plan to build n-number of construction.so a single class can create a n-number of methods and veriable depends on the class
//Second Topic  OBJECT
//what is Object?
*Object is a instance of Class
*If creating a object name state only lower case only
*Each class having a Own state and behavior
*A class is a blueprint for creating objects in object-oriented programming.
*State:* 
      * State is a variable that holds information about an object in object-oriented programming.
      *It represents a specific condition or value of that object at a particular time
  *Example (Car):
      In the real world, there are many cars, but each car belongs to a specific company like TATA, HONDA, or BMW. These company names represent the state of a car object. So, if a car object has the company name "BMW", then "BMW" is the state of that object.
*Behavior:
          *It is action-oriented.
          *It depends on the current state or context.
          *Behaviors can change when the state or environment                       changes.
Example (Car):
     *A Honda car has a behavior like:
 *Speeding up when you press the accelerator
 *Slowing down when you press the brake
 *The maximum speed it can reach is part of its behavior
SAMPLE PROGRAM:
public class Calse // class name
{
 public static void main(String args[])// main method
{
  System.out.println("calculater");//print statement
}
}
OUTPUT:Calculater
CALCULATER PROGRAM:
public class Calse //class name
{
    public int add(){ //veriable diclaration
    int a=5,b=6;
    System.out.println("a= 5 b= 6 = "+(a+b)); // printing statement
    return 5+6; // return statement
}
   public int sub(){
    int a=8,b=5;
    System.out.println("a= 8 b= 5 = "+(a-b));
    return 8-5;
}
 public static void main(String args[]){ // main method
    Calse calse = new Calse();//object creation
    int addition = calse.add();//call the object
    int subration = calse.sub();
    int multipication= addition * subration; //method
    int divition = addition / subration; 
    System.out.println("add * sub = :" +multipication);
    System.out.println("add / sub = :" +divition);
}
}
output:
