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

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 🙂
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?

Is taking what number expression What is it In one two equals to zero even is even of You will pass 502 Volume two equals to zero is one false is what is even so So that is only 5 It is also see expression is taking input in parameters with written values
For each method
It is a default methods Define in iterable interface
It is also available It is also available 8 stream class
ForEach method on o On stream object or collection object
Foreachlambda expression or method reference as input
Turn on collection interfac processing se so what is the topic of this
Whenever you exe statement Set of obj information you have to process the data also once you get the information from database collection
Pictures allowed only abstract methods armor extract methods allowed Suppose if they have written for each method extract method the the logic process the collection easily functional Lana expression three example same Whenever Whenever expression as an input I'm here they have written the lossing expression it will process What is the question What is the question inside the interface Define what type of methods
Default methods Is Whenever is expected by which one election is it extended by Set the method Next song Okay never use default methods static methods no way We will just use just for courage weather And it is very simple way default method using last
List list of integer using ForEach method

Method references
Method references are used to refer the method of functional interface easily using method references we can invoke 1 method with I'd of we can create method references to static method n instance methods
Relationship NPR calling simply ABC ABC compiler if there is a functional interface implementation is required with another name Whenever you are calling ABC Whenever you are calling ABC security Explain the you are adding that XYZ address
