how would you do this in a simple way? this is for a non graded practice lab 8.Complete the method publicArrayListremoveLenN (ArrayList list, intn), that removes all Strings with a lengthof n. Remember, the size of an ArrayListis dynamic - if you remove an element,the size of the list will shrink!

The objective of the question is to create a method in Java that removes all strings of a certain length from an ArrayList of strings.To solve this problem, we can use the Iterator interface provided by Java. The Iterator interface provides methods to iterate over any Collection. We can use the hasNext() method to check if there is a next element in the collection and the next() method to retrieve the next element. If the length of the string equals the specified length 'n', we can use the remove() method to remove it from the ArrayList. The remove() method of Iterator interface removes the current element in the collection, so it's safe to use it while iterating over the collection.Here is the Java code for the method:```java import java.util.ArrayList; import java.util.Iterator; public ArrayList<String> removeLenN(ArrayList<String> list, int n) { Iterator<String> it = list.iterator(); while(it.hasNext()) { String str = it.next(); if(str.length() == n) { it.remove(); } } return list; } ```In this code, we first create an Iterator for the ArrayList. Then we use a while loop to iterate over the ArrayList. Inside the loop, we get the next string and check its length. If its length equals 'n', we remove it from the ArrayList using the remove() method of the Iterator. Finally, we return the modified ArrayList.For example, if we call `removeLenN(['hello', 'world', 'java', 'code'], 4)`, it will return `['hello', 'world']` because 'java' and 'code' have length 4.In this solution, we created a method in Java that removes all strings of a certain length from an ArrayList of strings. We used the Iterator interface to safely remove elements from the ArrayList while iterating over it.
