Exercise 5.12: printAverage
Write a method named
printAverage that accepts a
Scanner for the console as a parameter and repeatedly prompts the user for numbers. Once any number less than zero is typed, the average of all non-negative numbers typed is displayed. Display the average as a
double, and do not round it. For example, a call to your method might look like this:
Scanner console = new Scanner(System.in); printAverage(console);
The following is one example log of execution for your method:
Type a number: 7 Type a number: 4 Type a number: 16 Type a number: -4 Average was 9.0
If the first number typed is negative, do not print an average. For example:
Type a number: -2
