You must modify the given list.**Your Answer:**```javapublic void removeOdd(ArrayList list){ // Implementation goes here}```**Feedback**Your answer could not be processed because it contains errors:- **line 3: error: size has private access in java.util.ArrayList**Explanation:In this task, you were required to write a method named `removeOdd` that accepts an `ArrayList` of integers as a parameter. This method should remove all odd integers from the list, and it must not return any value.The feedback indicates that your code was not processed due to an error on line 3. The error message specifies that there was an attempt to access the private `size` method of the `ArrayList` class. In Java, you cannot directly access private members of a class; instead, you should use public methods provided by the class, such as `size()`, to get the number of elements in the list.To correctly implement this method, you can use the following approach:1. Iterate through the `ArrayList` using an index; start from the end to avoid index shifting issues when elements are removed.2. Check if an element is odd.3. If it is odd, remove it from the list.Here is a possible correct implementation:```javapublic void removeOdd(ArrayList list) { for (int i = list.size() - 1; i >= 0; i--) { if (list.get(i) % 2 != 0) { list.remove(i); } }}```Explanation of the Correct Implementation:1. **Iteration from the End:** The for loop iterates from the last index to the first index. This approach helps avoid shifting issues when elements are removed.2. **Checking for Odd Elements:** Inside the loop, the condition `list.get(i) % 2 != 0` checks if the element is odd.3. **Removing Odd Elements:** If the element is odd, it is removed from the list using the `remove` method.This correct implementation ensures that all odd integers are removed from the `ArrayList`

Map

A map is defined as the name of a higher-order function in most of the programming languages that applies a given function to each element of a functor, such as a list, and returns a list of results in the same order. A map is also called the collection of values based on a key, i.e. a key and value pair. A map has its own set of keys. Duplicate keys are not permitted in the Map, although duplicate values are permitted. Because a Map cannot be navigated, it must be converted to a Set using the keySet() or entrySet() methods. For key-value association mapping, such as dictionaries, maps are ideal.

Question

**X595: removeOdd**

This method takes an `ArrayList` of integers as a parameter and does not return anything. The method will remove all of the odd elements in the given list. If there is no element in the given list, the list does not change. You must modify the given list.

**Your Answer:**

```java
public void removeOdd(ArrayList list)
{
// Implementation goes here
}
```

**Feedback**

Your answer could not be processed because it contains errors:
- **line 3: error: size has private access in java.util.ArrayList**

Explanation:

In this task, you were required to write a method named `removeOdd` that accepts an `ArrayList` of integers as a parameter. This method should remove all odd integers from the list, and it must not return any value.

The feedback indicates that your code was not processed due to an error on line 3. The error message specifies that there was an attempt to access the private `size` method of the `ArrayList` class. In Java, you cannot directly access private members of a class; instead, you should use public methods provided by the class, such as `size()`, to get the number of elements in the list.

To correctly implement this method, you can use the following approach:

1. Iterate through the `ArrayList` using an index; start from the end to avoid index shifting issues when elements are removed.
2. Check if an element is odd.
3. If it is odd, remove it from the list.

Here is a possible correct implementation:

```java
public void removeOdd(ArrayList<Integer> list) {
for (int i = list.size() - 1; i >= 0; i--) {
if (list.get(i) % 2 != 0) {
list.remove(i);
}
}
}
```

Explanation of the Correct Implementation:

1. **Iteration from the End:** The for loop iterates from the last index to the first index. This approach helps avoid shifting issues when elements are removed.
2. **Checking for Odd Elements:** Inside the loop, the condition `list.get(i) % 2 != 0` checks if the element is odd.
3. **Removing Odd Elements:** If the element is odd, it is removed from the list using the `remove` method.

This correct implementation ensures that all odd integers are removed from the `ArrayList`
