Question

How do I do this ? JAVA

Task: Write a complete runnable Java program named
Census (including the class definition and main method)
that lets a Census worker type in a sequence of ages for
each person they collected data from, and then prints out
the average of all of the ages inputted. The program should
repeatedly ask for an age of the next person until the
Census worker types in a negative number, after which it
will print the average age of all of the ages previously typed
in.
The following text shows one example log of the program's
output. The bold underlined text shows the user input and
does not need to be printed by your program as that is
what the user will type into the computer.
Welcome to the Census!
Input the ages of the population and we will compute the a
Next person's age negative to quit)? 14
(negative to quit)? 40
Next person's age
Next person's age
Next person's age
(negative to quit)? 39
(negative to quit)? 7
Next person's age (negative to quit)? -4
The average age is 25.0
Another example interaction is shown below.
Welcome to the Census!
Input the ages of the population and we will compute the a
Next person's age (negative to quit)? 27
Next person's age (negative to quit)? 10
Next person's age
(negative to quit)? 13
Next person's age
(negative to quit)? -1
The average age is 16.666666666666668
/hc

Next person's age (negative to quit)? 7
Next person's age (negative to quit)? -4
The average age is 25.0
Another example interaction is shown below.
Welcome to the Census!
Input the ages of the population and we will compute the a
Next person's age (negative to quit)? 27
(negative to quit)? 10
Next person's age
Next person's age
(negative to quit)? 13
Next person's age (negative to quit)? -1
The average age is 16.666666666666668
You can make the following assumptions:
. You should use the Scanner class to get user input.
• The user will type in at least one non-negative
number.
The user will always type in integer numbers and you
do not need to handle invalid input. Zero is
considered a valid number for this program.
•You do not need to worry about rounding the output
of the average. For example, it is possible for the
program to print out an average of
3.3333333333333335. You can just print the result of
the average without doing anything special to the
output.
