Loop and comparison optimization

Good day,

I have the following code:

    ArrayList<Integer> count = new ArrayList<>();
    for(int i=0;i<l.size();i++)
        count.add(0);

    for(int i=0;i<list.size();i++)
    { 
        for(int j=0;j<l.size();j++)
        {
            if(list.get(i).equals(l.get(j)))
            {
                int val = count.get(j);
                count.set(j, val+1);
            }   
        }
    }

My problem is that when running the two for loops and comparison, it takes an extremely long time to run, since the loops I am iterating through have:

size > 150000, also both "list" and "l" are ArrayLists

Is there any way to optimize this so that the time taken to run the program decreases?

I have looked at this: for loop optimization and many more pages however the solutions don't help in my instance.

Any help would be greatly appreciated.
