Answer:

The answer is True.

Explanation:

The final class cannot be extended because in java final keyword means "no modification". If it is applied to a variable or anything else then that value becomes a constant after that it cannot be modified.So in cases of class if final keyword is used it means that class cannot be extended.

Lorico [155]

Answer:

Hi there! Please find the answer below.

Explanation:

The program below demonstrates how each of the requirements can be coded in a simple Python script. To copy the array, we can use the copy() method of the array. To calculate the diff, we can use a few different techniques, so I have implemented it using a loop over the arrays and just storing and displaying the difference in the 2 arrays.

new_string.py

def add_test_score(score):

 test_score.append(score);

contact_hash = {}

test_score = []

print("Enter 5 test scores: ");

for x in range(0, 5):

   input_string = input("Enter test score " + str(x + 1) + ": ")

   add_test_score(int(input_string));

print(test_score);

test_score_copy = test_score.copy();

for e in test_score_copy:

   if e < 60:

       test_score_copy[test_score_copy.index(e)] += 10;

diff = [];

for e in test_score:

   print(test_score[test_score.index(e)]);

   print(test_score_copy[test_score.index(e)]);

   if not test_score[test_score.index(e)] == test_score_copy[test_score.index(e)]:

       diff.append(e);

print(diff);
