Different ways to read user inputs in Java

1. Using Scanner

   Scanner in = new Scanner(System.in);
   String name = in.nextLine();
   int number = in.nextInt();
   

2. Using BufferReader: BufferedReader is synchronous while Scanner is not. BufferedReader should be used if we are working with multiple threads. BufferedReader has a significantly larger buffer memory than Scanner. BufferedReader is a bit faster as compared to scanner because the scanner does the parsing of input data and BufferedReader simply reads a sequence of characters.

   BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
   String name = reader.readLine();
   

3. Using Console: Used to get input from the console. When used this to password, it will not be displayed to the user.

   String name = System.console().readLine();
