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.

import java.util.Scanner;
/**
* An example program to read a String from console input in Java
*/
public class CSharpCorner
{ 
 public static void main(String[] args) 
 {
 System.out.print("Enter a string : ");
 Scanner scanner = new Scanner(System.in);
 String inputString = scanner. nextLine();
 System.out.println("String read from console is : \n"+inputString);
 }
}

‘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’
