Java Scanner is a special Java class that is used to take inputs from all kinds of inout streams. The system console, files, StringBuilder, StringBuffers are to name a few.

The following code snippet gets input from system console and reads it using Java Scanner utility class.

  1. import java.util.Scanner;
  3. /**
  4. * An example program to read a String from console input in Java
  5. */
  6. public class CSharpCorner
  7. { 
  8.     public static void main(String[] args) 
  9.     {
  10.         System.out.print("Enter a string : ");
  11.         Scanner scanner = new Scanner(System.in);
  12.         String inputString = scanner. nextLine();
  13.         System.out.println("String read from console is : \n"+inputString);
  14.     }
  15. }

‘System.in’ means console, so in the above code we are telling Java compiler to accept input from the console, and save the accepted input into a String variable named ‘inputString’
