If you have any doubts, please give me comment...

import java.util.InputMismatchException;

import java.util.Scanner;

public class MaxMinGrades{

    public static void main(String[] args) {

        Scanner scnr = new Scanner(System.in);

        System.out.println("Enter as many student grades as you like. Enter a character to stop.");

        double highest = Double.MIN_VALUE;

        double lowest = Double.MAX_VALUE;

        double input;

        while(scnr.hasNextDouble()){

            input = scnr.nextDouble();

            if(highest<input)

                highest = input;

            if(lowest>input)

                lowest = input;

        }

        scnr.next();

        System.out.println("The highest grade is: "+highest);

        System.out.println("The lowest grade is: "+lowest);

    }

Answer 2

Answer:

Code:

import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
Scanner r = new Scanner(System.in);
float max = 0, min = 999999,f;
String inp; boolean b=true;
System.out.println("Enter as many grades you want. Enter a character to stop.:");
do{
inp = r.nextLine();
try {
f=Float.parseFloat(inp);
}
catch (NumberFormatException e)
{
break;
}
min=min<f?min:f;
max=max<f?f:max;
}while (b);
System.out.println("The highest grade is : " + max);
System.out.println("The lowest grade is : " + min);
}
}

Output:

input Enter as many grades you want. Enter a character to stop.. 12 56.4 23.5 78 84 The highest grade is : 84.0 The lowest grade is : 3.0 ... Program finished with exit code o Press ENTER to exit console.
