Task $2$: countArray $()$

Write a method countArray that takes an array of integers as a parameter. The method checks the integers that are even and in the range $2$ inclusive to $100$ exclusive and counts how many occurrences of each are in the array. The method should return a string that has all the values in the array along with the number of their occurrences in the array. For example: if the array has the following values: $2,10,10,98,3,146,$ the method should count the occurrence of integers that match the condition above. The string returned should be as follows $($use $\frac{?}{?}$

$)$:

$2$:$1$

$10$:$2$

$98$:$1$

If the array is empty, the returned string should be empty.

Examples:

$\backslash$table$[[$Call$,$Retun Value$],[,2$:$1$
