Solve please.

In the Java method, it finds the sum of elements in an integer array and then check if the sum is even or odd. Perform data flow testing on the method to verify correctness. Identify the variables and paths, then design test cases to cover all possible data flows in the code.

$```$

public class DataFlowTest $\{$

public static String calculateSumAndCheckEvenOdd$($int$[]$ numbers$)\{$

int sum $=0$; $//$ Define variable sum

for $($int num : numbers$)\{//$ Iterate through array

sum $+=$ num; $//$ Accumulate sum

$\}$

if $($sum $\%2==0)\{//$ Check if sum is even

return "Even";

$\}$ else $\{$

return "Odd";

$\}$

$\}$

$\}$

$```$

Expectation:

$-$ Identify Variables and Data Flow Paths.

$-$ Create a Data Flow Graph.

$-$ Design Test Cases for Complete Path Coverage.
