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

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

Use Collections.frequency option:

 List list = Arrays.asList("1", "1","1","1","1","1","5","5","12","12","12","12","12","12","12","12","12","12","8");
      int max = 0;
      int curr = 0;
      String currKey =  null;
      Set unique = new HashSet(list);

          for (String key : unique) {
                curr = Collections.frequency(list, key);

               if(max < curr){
                 max = curr;
                 currKey = key;
                }
            }

          System.out.println("The number "  + currKey + " happens " + max + " times");

Output:

The number 12 happens 10 times
