Question

write a program in java to input a number and print the largest digit from the number

Answer 1

Hi

How can I get the maximum digit from a number entered by the user?

Example: if user inputs: 1521, the program should output 5 as maximum.

Any help please?

NOTE: I want it to be made using 2 methods. AND don't give me answers with arrays. :)

This is what I wrote so far..

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

int number = 0;

System.out.println("Enter a number: ");

number = input.nextInt();

System.out.print("Max is: "+max(number));

}

public static int maximum(int max){

int num = 0;

while(num != 0){

int rightDigit = num % 10;

num /= 10;

if(rightDigit > max)

rightDigit = max;

}

return max;

}

When I run it, whatever number I write.. I get Max: 0.
