Answer to Question #314979 in Java | JSP | JSF for Inaya Ishaan

Question

Largest Digit

This one is a bit tricky. You're going to have to isolate each digit of the integer to determine which one is the largest, so good luck!

Instructions:

1. Input a 3-digit integer.
2. Print the largest digit in the integer.
3. Tip #1: Use % 10 to get the rightmost digit. For example, if you do 412 % 10, then the result would be the rightmost digit, which is 2.
4. Tip #2: On the other hand, use / 10 to remove the rightmost digit. For example, if you do 412 / 10, then the result would be 41.
5. Tip #3: You'd have to repeat Tip #1 and Tip #2 three times for this problem because the input is a 3-digit integer.

Instructions

1. Input one 3-digit integer.
2. Print the largest digit in the integer. (Hint: use % 10 to get the rightmost digit and / 10 to remove it)

Input

A line containing a three-digit integer.

173

Output

A line containing a single-digit integer

Answer 1

import java.util.Scanner;


public class App {
	
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		int number = in.nextInt();
		int largestDigit = 0;
		while (number > 0) {
			int digit = number % 10;
			if (largestDigit < digit) {
				largestDigit = digit;
			}
			number = number / 10;
		}
		System.out.println(largestDigit);
		in.close();
	}
