Explanation:
To protect from attackers gaining access by sitting on a certain configuration too long.
Three characteristics of an ideal encrytion scheme are:
1. The encryption sheme should be strong: the algorithm is imprevious to direct attack and attempts are derived.
2. The encryption scheme should create unique ciphertext from the same plaintext for each key permutation, among other traits.
3. It should take at least millions of years to break ideal encryption scheme, based on mathematical predictions.

Answer:
The ArrayList initial functionality is 5, there were 4 components.
Then, add 25 more elements by using add()calling 25 times So total number of elements after the completed operation would be 4 + 25= 29.
5th component will be introduced without calling ensureCapacity(); while adding 6th element-> ensureCapacity(2* 5+ 1) it will call, making the capacity 11.
So ArrayList's capacity will be 11.
Next 7th to 11th components will also be added automatically once the 12th element is added, it will name ensureCapacity(2* 11+ 1) and make the capacity 23.
While adding 24th dimension, ensureCapacity(2* 23+ 1) will be called again and this will make the capacity 47.
There will therefore be 3 (three) calls to ensure the feature Ability).
Elements of Rest 25th to 29th will be added seamlessly as ability becomes 47.
