Class VS Object

 Classes in java

  • Classes are used to store our code 
  • Classes in java can be created using class keyword
  • Class is like a blueprint where we can write all of our requirements 

Ex:-  fileName- Demo.java

class Hello{

 public void print(){

System.out.print("It is in print() in Hello class");

}

}


Objects in java

  • Objects are used to store the attributes of a class
  • It is like instance of a class
  • It stores all attributes of a class
  • If we want to access the features of a class we use objects

Ex:- fileName- Demo.java       <Same file>

class Demo {

public static void main (String []args){

Hello h=new Hello();

// 'Hello h 'is a reference of class Hello class

// new Hello() is a instance of a class Hello

// By combining the two we get object it means it stores the all attributes/ features of class Hello 

// .(dot) is used to access the specific features of the class 


h.print();

}

}

Constructors in java

 Java Constructors Constructor is nothing but a method with a class name It doesn't return any values  We don't write any return type of the constructor It is used to initialise the values when the object is created In java there is constructor called default constructor it is automatically initialize when there is no constructor is assigned We can also give parameters in the constructor so at the time of initialize we can assign some value into the class. It is known as parametric construction If we create a any constructor in a class then the default constructor will not work so we need to write the default constructor also if we want to use them Ex: 1) Default constructor class Hello{ public int a=10; public int b=20; } class Hel{ public static void main (String []args){ Hello h=new Hello();// using default constructor  System.out.print(h.a+h.b);//1020 } 2) Constructor with no parameters   class Hello{ public Hello(){ System.out.print("Hello"); } } class Hel{ publi
