Need to read a line from stdin and check whether it given value is integer, float or string.

Coding:

/* Read input from STDIN. Print your output to STDOUT*/

import java.io.*;
import java.util.*;
public class MyCode {
   public static void main(String args[] ) throws Exception {

//Write code here
Scanner input=new Scanner(System.in);
if(input.hasNextInt())
System.out.println("This input is of type Integer.");
else if(input.hasNextFloat())
System.out.println("This input is of type Float.");
else if(input.hasNextLine())
System.out.println("This input is of type String.");
else
System.out.println("This is something else. ");

   }
}


Output:

-2580
This input is of type Integer.
