In this video, we will be discussing how to get user input in java using Scanner Class and we will also see the alternative was of using Scanner class is System.in.read()

Scanner Class:
-------------------------
Scanner Class is a predefined class present in java which is having some predefined method using which you can get the user input.

Some of the methods are mentioned below:
1)nextInt();
2)nextLong();
3)nextFloat();
4)nextDouble();
5)nextLine();
6)nextChar();
and many more.

System.in.read();
-----------------------------
In the case of System.in.read() we can find that it basically read one character at a time and even it get the ASCII value of it.

Because of that, we need to do typecasting into char. to see the actual result.

And if you want to read more than one character then looping will the best option to read and print the value.
