Write a function in Java that will count the number of "streaks" of consecutive numbers in an array of integers.

For example

countStreaks$([1,2,2,3,3,2,4])$ should return $2$ because there of the streak of $2\text{'}$s and the streak of $3\text{'}$s$.$

countStreaks$([1,1,1,1])$ should return $1$ because there is a single streak of $41\text{'}$s$.$

countStreaks$([1,2,1,2])$ should return $0$ because there is no streak of consecutive same numbers.
