Answer to Question #330250 in Java | JSP | JSF for maica

Question

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.

Answer 1

import java.util.Scanner;
//Implement class Cube
class Main {
  
  public static void main(String[] args) {
    System.out.print("Please enter three digits number: ");
    Scanner cin=new Scanner(System.in);
    int a=cin.nextInt();
    int mxDigit=0;//Max digit save here
    while(a!=0)
      {
        mxDigit=Math.max(mxDigit,a%10);
        a/=10;
      }
    System.out.println("Max Digit for given number: "+mxDigit);
  }
}
