Question 1In Java, which of the following are characteristics of an int (select two)a. You can use operators on itb. It holds the actual value of a numberO c. It holds a reference to a numberOd. It is a class.Strings in Java are really annoying, which of the following statements about them are true (and no we';renot giving a hint about how many answers are correct for this one!):a. Strings can be manipulated with the + operatorb. Strings can use the operator to remove the content of one string from anotherc. Strings are built into Java at a fundamental level.d. Strings store their text as an array of characters.Imagine that we have a class called Car. Which three of the following are most likely to be attributes of it:a. paintColourO b. multistoreyCarparkO c. insuranceStatusO d. enginee. road Sort the following Java keywords into order starting from most visible and accessible at the top to least atthe bottom.protecteddefaultpublicprivate

Need help with this java problem. Some Websites impose certain rules for passwords.Write a method that checks whether a string is a valid password. The method must takes a password as a parameter and return a boolean value. If the password is valid, returns true, otherwise, return false. Suppose the password rules are as follows:- A password must have at least eight characters.- A password must contain only letters and digits.- A password must contain at least two digits. Please make sure you write a comment line to document what your method does. Write a program that prompts the user to enter a password, then call the method that checks the password, and displays "Valid Password" if the rulesare followed, or Invalid Password otherwise. The main program must allow the user to check multiple passwords. It should ask the user "Do you want to continue checking anther password (y/n)?"
Random Numbers: Most computer programs do the same thing every time they run; programs like that are called deterministic. Usually, determinism is a good thing, since we expect the same calculation to yield the same result. But for some applications, we want the computer to be unpredictable. Games are an obvious example, but there are many others, like scientific simulations. We have already seen java.util.Random, which generates pseudorandom numbers. The method nextInt takes an integer argument, n, and returns a random integer between 0 and n - 1. Assignment: For this assignment you will write a program in java to simulate a guessing game. Your program will generate a random number in a certain range (let the user define the range) and ask the user to guess what number it is. Give the user a certain number of tries while you narrow down the possibilities. For example, let's say the number generated is 67 and the user has 5 tries, this could be your program's output: This is a guessing…
In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

please quickly thanks ! use java
Instructor note: This lab is part of the assignment for this chapter. This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 miles

Understanding ifStatements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is made of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge). A variable for the number of characters initialized to 8 (numChars). A variable for the color of the characters initialized to "gold" (color). A variable for the…
