Write a program to check whether an int type number (taken as input) is a 3-digit number divisible by three or not.
Solution
import java.util.*;
class ThreeDigit
{
public static void main(String arr[])
{
int n;
Scanner sc=new Scanner(System.in);
System.out.println(“Enter an integer:”);
n=sc.nextInt();
if((n>=100 && n<=999 || n>=-999 && n<=-100) && n%3==0)
System.out.println(“3-digit number divisible by 3”);
else
System.out.println(“Not a 3-digit number or divisible by 3”);
}
}
