Find the element with highest occurrences in an array [java]

Question

I have to find the element with highest occurrences in a double array. I did it like this:

int max = 0;
for (int i = 0; i < array.length; i++) {
       in

Here is Ruby SOlution:

def maxOccurence(arr)
  m_hash = arr.group_by(&:itself).transform_values(&:count)
  elem = 0, elem_count = 0
  m_hash.each do |k, v|
    if v > elem_count
        elem = k
        elem_count = v
    end
  end
  "#{elem} occured #{elem_count} times"
end

p maxOccurence(["1", "1","1","1","1","1","5","5","12","12","12","12","12","12","12","12","12","12","8"])

output:

"12 occured 10 times"
