Question

Now implement the removeodd method in Java?

Answer 1

The removeodd method in Java can be implemented by iterating through a collection with an Iterator, checking if each number is odd and removing it if so. This method works effectively with collections like ArrayList and ensures that only even numbers remain in the list after execution.

Step-by-step explanation:

Implementing the removeodd Method in Java:

Implementing a method to remove odd numbers from a collection in Java involves iterating over the collection and removing each number that is not divisible by two. Below is a step-by-step example of how you might implement this in a class that operates on an ArrayList of integers:

import java.util.ArrayList;
import java.util.Iterator;

class Example {
public static void removeodd(ArrayList list) {
Iterator it = list.iterator();
while (it.hasNext()) {
Integer number = it.next();
if (number % 2 != 0) {
it.remove();
}
}
}
}

This method uses an Iterator to traverse the list, checking each Integer for oddness. If an integer is found to be odd (the remainder of division by 2 is not zero), that integer is removed from the list.
