Answer:
The code to this question can be given as:
Code:
public interface Test //define interface
{
public abstract Duration getDuration(); //define method
getDuration.
public abstract Result check(int a);
//define method
check .
public abstract double getScore();
//define method getScore.
}
Explanation:
In the above code, we define an interface that is "Test" inside an interface, we define three methods that can be defined as:
- First, we define a method that is "getDuration" that method returns Duration as an object.
- Second, we define a method that is "check" this method accepts an integer parameter that is a and return Result.
- The third method is "getScore" this method will return a double value.
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);
The answer for the 1st blank is text.
Answer: Fourth- generation language
Explanation:Structured Query Language (SQL) is the language that is in the form of database structure which helps in the manipulation of the data and management as well.
SQL is considered as the fourth generation language because it is used for the accessing of the data from the database.It is also known for the advancement in the third generation language and thus also improving the language interface with users.
