Write allows you to print something on console
Like if write hello world it print on console and line means it go to next line after printing that word

Read as in it allow you to take input from console and again line is same cursor goes to next line

So if u want to print hello with username

String username = console.readLine();
Console.WriteLine("Hello "+username);

So in console if u put input as Nitin

Output will be

Hello Nitin

And cursor on the next line
