Since JDK 8, It is allowed to define Next static and default methods We access the static methods using the identity of interface an extract method default through object reference
Static
The body definition
Default What is a static method
The second one is
Abstract methods
So in the child class
I can how to access only one type of variable is allowed

Of variable method last name Next I want to access default methods object reference how to create d object Tell me
First obj = new. second()

What type of methods

Static methods

As it is automated some spelling mistakes possible

Interface that allowed it to define Next1 abstract
Define functional using the annotation functional At the rate functional interface
Example
I just want to make it Define 2 methods nor want to make it functional interface I should write at the rate functional interface annotations Now give this interface You are allowed to define only one abstract method Can you try to write the second text whether you will get another message and it is not allowed interface allowed any numbers staticvod M2
Only have talking about the abstract method How many only 1
Public void n c the same story creating object for What is the method name

Lambda expression

Expression is a line of code
Expression Is used to implement the functionality interface simple way 1
The way
Usin last name class
I'm using the same thing 1 Is the second classs It is implementing what first
Public implementation of main it made objects for interface how to create

What we discuss If there isn't in class
The class inside another class or inside another method anonymous inner clasnside the method Play local Now only main in mai class but here nc lass Can you create an object first is an interva create object for first only first OBC 812 you first inside the main You will override this method here
Public void class
So what is anonymous inner class defining Is my name in class When the means to implement the interface inside the method
Advantages :-
One arrow whatever you write you can write here I'm calling the same from here to here everything removre Is active from open and calling the same method automatically recognize because Is recognised 1st interface whatever the method name not required only one method is the Whatever you call the call automatically recognize that function from JDK 8
Implement

Interfaces Implement the three ways
1.) Through class
2.) Through true anonymous in a class
3.) Through lambda expression

Through annonymous inner class

Defining a class without identity

Annonymous Are using to implement interfaces inside the inside the method

Through lambda expression

I remove you object creation public

Kindly use these only for reference not for knowledge spelling mistakes is there 🙂

But full spoken word will be there

Lambda expression with parameters

Inside there is a method which is taking arguments So now we are
In main calc obj = is taking(int1 , int 2 )
I want to print the only added value
How do you get right calling
Passing value


If the interface method is taking parameters not required data types

Lambda exp with parameters and written values
Is not only taking the parameters
It is written in the value
I've been adding two numbers it will return the decision
In the sameway
Simply directly you can write like this
X+y
8 + 5 is also not required This is actually fun expression
We are passing here retu Whenever you are calling this one at
Return Statement also not required is a single statement it will return the value directly system. Is out.println
What is written will get displayed?

Even or odd program using lambda expression
