16. Which of the following statements is true? a. An interface effectively has the exact same functionality as a java class b. An interface is like a blueprint - any class implementing an interface must implement all the functions defined in an interface c. It is possible to have concrete function definitions inside an interface d. A class can not implement more than one interface 17. Does Java use call by value or call by reference in function calls? a. Call by reference b. It depends on the context c. Call by value 18. What is the main use case of getter and setter functions in a Java classes? a. It is mandatory to have them in a Java class. b. Setting and retrieving values of variables using getters and setters is faster than directly accessing the variables. c. They allow us to get and set the values for variables declared as private. d.

Overload the following operators. > < <=
The language we are using here is in Racket. Please enter the following code: (cond ((equal? 16 3) (+ 3 8)) ((equal? 16 8) 12) (else (* 6 3))) Write the return value for the above code. If replacing all of the 16's in the above code with 8, what is the return value? What about replacing the 16’s with 3? What does the cond function do?
Hi there, You mention what should be changed in a comment in the function multiply right? but you dint cgange it in the code, right? (i see no difference). besides, my error was in the transpose function. The multiply function actually passed the tests. Do you see any errors in the transpose function? Thanks
Use the Bash shell for the completion of this project.Develop a shell scripting application that allows the user to perform some advanced mathematicaloperations. Task 2: Find the terms of any linear sequence given by the rule Term = a*n + b, where a and b are integers specified by the user and n is a positive integer and print them in order (for example if the user inputs a=3, b=-4, the first few terms that should be printed are -1, 2, 5, 8, 11…). The user also will specify how many terms the program should print. In addition, the program should print the sum of terms found and a count of how many odd terms were found.

Fix an error and show it please? And here are the information about the homework and for the error too. def kwargs_to_args_decorator(*args, **kwargs): This question is meant to test your knowledge of creating a decorator that accepts an arbitrary number of positional and keyword arguments, to decorate a function that accepts an arbitrary number of positional and keyword arguments, and alters the arguments before passing them to the decorated function. When the decorated function is invoked, this decorator should modify the arguments the decorated function receives. This decorator should filter out all positional arguments passed to the decorated function, which are found in the positional arguments passed to the decorator when the decorator was initialized. It should also filter out all keyword arguments with keys that are found in the keyword arguments given to the decorator when the decorator was initialized. After performing the modifications to the arguments, the decorator should…
How to Think Like a Computer Scientist: Learning Python 3. Chapter 6, Question 18 & 19. Write the function f2c(t) designed to return the integer value of the nearest degree Celsius for given temperature in Fahrenheit. (hint: you may want to make use of the built-in function, round. Try printing round.__doc__ in a Python shell or looking up help for the round function, and experimenting with it until you are comfortable with how it works.) Now do the opposite: write the function c2f which converts Celsius to Fahrenheit.

Hello, Can someone please help me how to write these functions in Java, But only using the java bit operators & (and), | (or),^ (xor), >> (right shift), >>> (right shift logical), and << (left shift)? Thank you!
Python question, please us a docstring and have comments throughout code Write a function getInteger() that takes two integers num1 and num2 as parameters. If num1 > num2, then the function prints an error message and returns 0. If num1 is equal to num2, the function returns the common value. For cases where num1 < num2, the function prompts the user to enter an integer greater than or equal to num1 and less than or equal to num2 and returns the first valid integer that the user enters. If the user enters something that is not an integer value, the programs should display an error message and re-prompt the user to enter a valid integer Below are some sample executions of the function. Use the while and if-elif statements and a try/except in the solution. Don’t forget to include the docstring and comments. Copy and paste or screen shot the code and the thirteen test cases shown below in your submission. . >>> getInteger(5,4) 5 and 4 are not valid parameters 0…
