Write a method called removeInRange that accepts four parameters: an ArrayList of integers, an element value, a starting index,

Murrr4er [49]

Answer:

public static void removeInRange(List<Integer> list, int value, int start, int end) {

for (int i = end - 1; i >= start; i--) {

if (list.get(i) == value) {

list.remove(i);

}

System.out.println(list);

}

Explanation:

- Create a method named removeInRange that takes four parameters, a list, an integer number, a starting index and an ending index

- Inside the method, initialize a for loop that iterates between starting index and ending index

- If any number between these ranges is equal to the given value, then remove that value from the list, using remove method

- When the loop is done, print the new list
