Thread: Calculate the average

I wrote a code to calculate the average of numbers. The problem is that you only can insert whole numbers. Does anybody know how I can change the code so that I can insert float numbers?

Here's the code i did with the help of a tutorial:

Dies ist der Code:

public class main_class {
public static void main(String[] args){
String sentinel = "";
int sum = 0;
int counter = 0;
double mean = 0.0;
Scanner NumScanner = new Scanner(System.in);

System.out.println("Enter numbers to add. Enter \"d\" when done.");

System.out.print("Enter number: ");
sentinel = NumScanner.next();
System.out.println();

while(!sentinel.equals("d") && !sentinel.equals("D")) {
sum += Integer.parseInt(sentinel);
counter++;

System.out.print("Enter number: ");
sentinel = NumScanner.next();
System.out.println();
}

mean = (sum*1.0)/counter;

System.out.println();
System.out.println("The arithmetic mean is: " + mean +".");
}
}

Original code below. Dont know the answer as im not too good at coding.

public class main_class {
public static void main(String[] args){
String sentinel = "";
int sum = 0;
int counter = 0;
double mean = 0.0;
Scanner NumScanner = new Scanner(System.in);
 
System.out.println("Enter numbers to add. Enter \"d\" when done.");
 
System.out.print("Enter number: ");
sentinel = NumScanner.next();
System.out.println();
 
while(!sentinel.equals("d") && !sentinel.equals("D")) {
sum += Integer.parseInt(sentinel);
counter++;
 
System.out.print("Enter number: ");
sentinel = NumScanner.next();
System.out.println();
}
 
mean = (sum*1.0)/counter;
 
System.out.println();
System.out.println("The arithmetic mean is: " + mean +".");
}
}

Change the integers & doubles to floats and let the scanner read it as a float [scan.nextFloat();].
Note: make sure you import the scanner class (java.util.Scanner.

Thank You!
