How to check whether input value is integer or float?

Suppose 312/100=3.12 Here i need check whether 3.12 is a float value or integer value, i.e., without any decimal

Answer 1

You can use Scanner Class to find whether a given number could be read as Int or Float type.

 import java.util.Scanner;
 public class Test {
     public static void main(String args[] ) throws Exception {

     Scanner sc=new Scanner(System.in);

     if(sc.hasNextInt())
         System.out.println("This input is  of type Integer");
     else if(sc.hasNextFloat())
         System.out.println("This input is  of type Float");
     else
         System.out.println("This is something else");
     }
}

Also:

(value % 1) == 0

would work!
