Comment

A number is called a sunny number if the number next to the given number is a perfect square. In other words, a number N will be a sunny number if N+1 is a perfect square.

import java.util.Scanner;  
public class SunnyNumberExample2  
{  
//user-defined function that determines all the sunny numbers  
public static boolean isSunnyNumber(int number)   
{  
//determines the square root of number+1 using Math.sqrt() method  
if(Math.sqrt(number+1)%1 == 0)  
return true;  
else   
return false;  
}  
//driver code  
public static void main(String args[])   
{  
//lr is lower range and ur is upper range  
int lr = 0, ur = 0;  
Scanner scan = new Scanner(System.in);  
System.out.print("Enter lower range: ");  
//reads an integer (lr) from the user  
lr = scan.nextInt();  
System.out.print("Enter upper range: ");  
//reads an integer (ur) from the user  
ur = scan.nextInt();  
System.out.println("The Sunny number from "+ lr + " to "+ ur+" are: ");  
for(int i=lr; i<=ur; i++)   
{  
//calling user-defined number  
if(isSunny(i))  
System.out.print(i +" ");  
}  
}  
}
