The Greatest and the Least of These

Write a program with a loop that lets the user enter a series of positive integers. The user should enter $-99$ to signal the end of the series. Any negative number other than $-99$ must be rejected with a message $$ERROR: no negative values other than $-99$ accepted!$.$ After all the numbers have been entered, the program should display the largest and the smallest numbers entered. If no numbers were entered $($user entered $-99$ right away$)$ a message $$No numbers were entered$$ must appear.

Name your solution project GreatestAndLeast.java.

Use $$The greatest of a set of numbers$$ algorithm $($see below$)$ to solve the problem.

Requirements:

Your code must run correctly on the test cases provided below.

DO NOT use arrays or ArrayLists to store the numbers in the series. Numbers must be analyzed on the spot and $$discarded$.$

Error message in response to negative value other than $-99$ must include word ERROR to pass the CodeGrade tests.

$$No numbers were entered$$ must appear when no numbers were entered.

When user entered at least one integer other than $-99$ the report must list first the largest number, with the word $$largest$$ preceding it$,$ and then the smallest number, with the word $$smallest$$ preceding it$.$ See sample user interaction for more details. These details are important to pass the CodeGrade tests.

$$The greatest of a set of numbers$$ algorithm:

Get $($input$)$ the first number, set it to be the greatest one for now.

Get the next number.

If the new number is bigger than the $$greatest$$ one $$ set the new one to be the $$greatest$.$

Repeat steps $2-4$ until all the numbers are consumed.

Test cases

User input $(1$ number$)$: $-99$

Produces output $$No numbers were entered$$

Input $2$ numbers: $1,-99$

Output: the largest number: $1$ ; the smallest number: $1$

Input $5$ numbers :$1,2,55,0,-99$

Output: the largest number: $55$ ; the smallest number: $0$

User interaction sample #$1$

Enter a positive integer number. Enter $-99$ to stop input.

$=>-99$

No numbers were entered

User interaction sample #$2$

Enter a positive integer number. Enter $-99$ to stop input.

$=>1$

Enter a positive integer number. Enter $-99$ to stop input.

$=>5$

Enter a positive integer number. Enter $-99$ to stop input.

$=>-6$

ERROR: negative integers other than $-99$ are not allowed.

Enter a positive integer number. Enter $-99$ to stop input.

$=>2$

Enter a positive integer number. Enter $-99$ to stop input.

$=>-99$

the largest number: $5$ ; the smallest number: $1$

User interaction sample #$3$

Enter a positive integer number. Enter $-99$ to stop input.

$=>1$

Enter a positive integer number. Enter $-99$ to stop input.

$=>-1$

ERROR: negative integers other than $-99$ are not allowed.

Enter a positive integer number. Enter $-99$ to stop input.

$=>-99$

the largest number: $1$ ; the smallest number: $1$
