what is array is this a Class
java.sql.Array or reflect.Array :confused:

In simple way, loop the array on each element and at the same time maintain two variables to hold largest values.

...in case you think of replacing the simple array with a ArrayList obj you can very well go for the Collections.max(Collection obj) to get the maximum value.

Yes, it's true. But he is looking to do it in a loop.

Something like this may help in that sense, I think.

Code:

---

    private void findMax(ArrayList arl) {
        int max = 0;
        for(int i = 0; i < arl.size(); i++) {
            if(Integer.parseInt((String) arl.get(i)) > max) {
                max = Integer.parseInt((String) arl.get(i));
            }
        }
       
        System.out.println(max);
    }
