Answer:
true true
Explanation:
The code snippet first declare an arraylist called list. Then, a date object d is created. The object d is added to the arraylist twice.
Then inside the display statement, there are two boolean expressions. They both check if the element in index 0 and index 1 of the arraylist are the same and if they refer to the same object location in the memory.
The object in index 0 and index 1 are the same and they refer to the same object location in the memory hence the output is true true.
