Write a Java program to test if a double number is an integer

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.*;
public class Javamathexcercise {
 public static void main(String[] args) {
  double number = 55.10;
  if ((number % 1) == 0) {
   System.out.println("It is not a double number");
  } else {
   System.out.println("It is a double number");
  }
 }
}

Result:

It is a double number
