Question

Suppose an ArrayList list contains {"red", "red", "green"}. What is the list after the following code? String element = "red"; for (int i = list.size() - 1; i >= 0; i--) if (list.get(i).equals(element)) list.remove(element);

Answer 1

Answer:

The output of the given code as follows:

Output:

{"red", "green"}

Explanation:

• In the given code a list is defined, which contains three elements, which are "red, red, and green". In the next step, a string variable "element" is initialized with a value that is "red".

• Then a for loop is declared, that counts list size, and inside the loop and if block is declared, that compares the value list with element variable then it removes from the list.
