Pseudocode, Test Plan, Flowchart and Test Case for this $($JAVA$)$:

$($Count positive and negative numbers and compute the average of numbers$)$

Write a program that reads an unspecified number of integers, determines

how many positive and negative values have been read, and computes the

total and average of the input values $($not counting zeros$).$ Your program ends

with the input $0.$ Display the average as a floating$-$point number.

Sample Run $1$

Enter an integer, the input ends if it is $0$:$\{\begin{array}{ccc}\text{:}[1,& 2,-1,& 3]\end{array}$

$0$

The number of positives is $3$

The number of negatives is $1$

The total is $5\mathrm{.}0$

The average is $1\mathrm{.}25$

Sample Run $2$

Enter an integer, the input ends if it is $0$:$0$

No numbers are entered except $0$

Sample Run $3$

Enter an integer, the input ends if it is $0$:$2345$

$0$

The number of positives is $4$

The number of negatives is $0$

The total is $14$

The average is $3\mathrm{.}5$

Sample Run $4$

Enter an integer, the input ends if it is $0$: $4,3,2$

$-10$

The number of positives is $2$

The number of negatives is $2$

The total is $0$

The average is $0\mathrm{.}0$
