Check if a large number is divisible by 3 or not in java
If the sum of the digits of a number is divisible by 3, then the number is divisible by 3.
Some examples of numbers divisible by 3 are as follows.
- The number 85203 is divisible by 3 because the sum of its digits (8 + 5 + 2 + 0 + 3 = 18) is divisible by 3.
- The number 79154 is not divisible by 3 because the sum of its digits (7 + 9 + 1 + 5 + 4 = 26) is not divisible by 3.
Program
import java.util.Scanner;
public class DivisibleBy3 {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a number :");
String num = sc.nextLine();
int digitSum = 0;
for(int i = 0; i<num.length(); i++) {
digitSum = digitSum + num.charAt(i)-'0';
}
if(digitSum % 3 == 0) {
System.out.println("Given number is divisible by 3");
} else {
System.out.println("Given number is not divisible by 3");
}
}
}Output
