TODAY IS DRIVE SO COME TO INSTITUTE

Bubble sorting

Not 100% sure about drive 😂

Depends upon situation possible drive

Run the code

import java.util.List;
import java.util.stream.Collectors;
import java.util.stream.IntStream;
public class Billions {


public class PrintBillionNumbers {
public static void main(String[] args) {
List<Integer> list = IntStream.rangeClosed(1, 1000000000).boxed().collect(Collectors.toList());
list.forEach(System.out::println);
}

4th floor React-Js class those who don't have aof drive

COME TO CLASS REACT-JS CLASS

MERN STACK
M= MONGODB is database
E= EXPRESS-JS is framework
R= REACT-JS is frontend
N= NODE-JS is backend


node-js depending on express-js
express-js used to develop rest api
express-js used to do (get, post , put, delete)requests

STEP1- react-js sends request to node-js
STEP2- node-js sends request ri mongodb
STEP3- mongodb sends back request to nodejs
STEP4- node-js sends back request to react-js

mongodb:-

it is NoSQL database
it supports JSON
it is light-weight database
it follows the mongoDB protocol
it bydefault running on Port no.27017

Difference b/w SQL & NoSQL databases ?
SQL NoSQL
1. oracle , MYsql 1. mongoDB , casandraDB
sqlServer


2. tables , primaryKey 2. collections , _id
3. databases , records 3. databases , documents
