Find the largest digit of a number in Java | Java Programming Solutions | Ask The Code

Problem:

Looping a number and taking away each digit of it is so much fun, but I wanted to try out a much more complex task: getting the largest digit among them all.

Think you can handle the job?

Input Sample:

214

Output Sample:

4

Code:

import java.util.Scanner;

class solution_Lar_Digit{
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);

		int n = sc.nextInt();
		int max = 0;
		while(n != 0){
			int val = n % 10;
			if (val > max) {
				max = val;
			}
			n = n / 10;
		}
		System.out.println(max);
	}
}
