check if elements in the fist array are in the same order on another array?

Question

I have a problem I have two arrays let's say arr1=[3, 1 ,6 ,2 ,5 ,8 ,4 ,7 ,9 ,10] and arr2=[9 ,6 ,5, 8, 4, 7, 3 ,1 ,2 ,10] the problem is I want to count how many group of elements were as the same order in both arrays so the output will be ---> 2 since we have "8 4 7" and "3 1" are duplicated with same order this is my code I can't handle the right solution Any help? BTW this is my first post on stack overflow I was stuck for two days if you want more details I can tell you more!

    int len = arr.length;

      // then return the index
      if (arr[i] == t) {
