Java a) You are writing a method named getAverage that runs in the main class and is called by the main method. Its only parameter is a 2D double array named values, and it returns a double that is the average of all the values stored in it. Write the complete method header for this method. Include the opening brace for the method. b) Given a String variable named firstName that has been declared and initialized, write the complete statement needed to make firstName all lowercase.

Sultan Qaboos University Department of Computer Science COMP2202: Fundamentals of Object Oriented Programming Assignment # 2 (Due 5 November 2022 @23:59) The purpose of this assignment is to practice with java classes and objects, and arrays. Create a NetBeans/IntelliJ project named HW2_YourId to develop a java program as explained below. Important: Apply good programming practices: 1- Provide comments in your code. 2- Provide a program design 3- Use meaningful variables and constant names. 4- Include your name, university id and section number as a comment at the beginning of your code. 5- Submit to Moodle the compressed file of your entire project (HW1_YourId). 1. Introduction: In crowded cities, it's very crucial to provide enough parking spaces for vehicles. These are usually multistory buildings where each floor is divided into rows and columns. Drivers can park their cars in exchange for some fees. A single floor can be modeled as a two-dimensional array of rows and columns. A…
Code a called method that takes two parameters, an array of double as reference type and a double value. In the method, manipulate the argument by incrementing the value of the array. Note that you are not required to manipulate the entire array.
True or False? Arrays cannot be passed as parameters, but must be used only in the main method.
1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…

MONTY HALL LAB write this code in python and use # to answers questions - You are only allowed to use the following functions/methods: print(), range(), len(), sum(), max(), min(), and .append(). It is not mandatory to useall of these functions/methods. In this lab, you will write a code that simulates the Monty Hall Game Show. Thegame host gives the participant the choice of selecting one of three doors. Twodoors has a goat behind them and one door has a prize. The set of choices arerandomized each round. The participant needs to select the door with the prizebehind it. When the participant selects a door, the game host reveals a door with agoat behind it. The game host opens a door (different from the one selected by theparticipant) that has a goat behind it. The participant is then given the option tochange their choice. When you run your code, the code would display a message prompting the user toinput their door choice, labelled as 1, 2, and 3. Then the code will display a…
Java Code Write a Windspeed class that stores the total winsoeed for each of 12 months into an array of double windspeedmeasures. The windspeed shoukd be collected from the user. The program should have methods that return the following: - total windspeed fir the year - the average monthly windspeed (Include single line comments and populating the array with a Scanner)
JAVA Problem description:You are to write a program called Seasons that prompts the user for a month and day and displays the season in which that date occurs. For reference, we will use the following date cutoffs for the various seasons: Winter December 21 – March 19 Spring March 20th – June 20th Summer June 21st – September 20th Fall September 21st – December 20th Data Validation For this program, you'll write a specific method to perform data validation based on the month and day entered. More specifically: Month – the month entered must be a valid month of the year (January – December). Day – the day entered must be a valid day for that month: January, March, May, July, August, October, December have 1-31 days. April, June, September, November have 1-30 days. February has 1-28 days (do not worry about leap years) Required program decomposition String getMonth(Scanner console) This method is called from the main method and should prompt for the month as a string…
2- Create a class named Test. The class must contain the main method. In the main method, you should create three objects from class Employee and store them in an array of type Employee (you must prompt the user to enter name and salary for each object). Then, you should print the name and salary of each object (using either the getters or the toStrong() method).
JavaDriver Program Write a driver program that contains a main method and two other methods. Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.
