Question

Use a sentinel while loop that repeatedly prompts the user to enter a number, once -1 is entered, stop prompting for numbers and display the maximum number entered by the user.

I am struggling to have my program print the math function. Here is what I have so far:

import java.util.*;
public class MaxSentinel
{
public static void main(String[] args)
{
  
Scanner input = new Scanner(System.in);
System.out.println("Please enter a value. Press -1 to stop prompt.");
int number = 0;
do
{
System.out.println("Enter a value.");
number = input.nextInt();
}
while(number != -1);
  
  
}
}
