Which of the following is true about the way method parameters are passed in Java? (select all that apply): (a) Arrays cannot be passed as parameters. (b) The invoked method receives a copy of passed references which can be modified (reassigned) by the method, but the original references in the calling code block will never be changed. (c) The called method can invoke accessible methods that a passed reference/object has to offer. □しろいしかく (d) Parameters can be passed "by address" - exactly how address pointers are used in C++.

problem statement: Write a java classStringCheckto do the below given checks on accepted string or strings. Each function should be coded in separate methods of the class. Give appropriate instance variables to implement the method. The user should be able to enter the string through the main function in Main class. Use a constructor to initialize the String entered by the user. Use the Main class to test all the methods in StringCheckclass. The programs should have the below given checklist: 1)Define classStringCheck with required instance variables 2)The StringCheck class should have six methods to do the below functions: *Check if the user entered string is a simple sentence? (Starts with capital letter, Ends with period, space between words). *Check if the user entered string is a question? (Check if the string starts with ac apital letter ends with a question mark, space between words) *Check if the user entered string have numbers in it? *Check if string is a valid email *Check...

Consider the following program written in C pseudocode: int a = 1; /* global */ void foo(int x){ a++;x = x + 2; } void main(){ foo(a); } For each of the following parameter-passing methods, what will be the values of a and b after running the program? 1) Passed by value 2) Passed by reference 3) Passed by value-result

5. Declare a class called coordinate. This is to represent 3 dimensional Cartesian coordinates (x, y and z).Define the following methods cumulatively in Java cumulatively:a. Constructorb. Display, to print values of membersc. Add_coordinates, to add three such coordinate objects to produce a resultant coordinate object.Generate and handle exceptions if x, y and z coordinate of the result are zero.d. Main, to show use of the above methods.

What is the difference between a method, a function, and an object?

C++ PROGRAMS: Question#1:Define a class for rectangle objects defined by two points, the top-left and bottom-right corners of the rectangle. Include a constructor to copy a rectangle, a method to return a rectangle object that encloses the current object and the rectangle passed as an argument, and a method to display the defining points of a rectangle. Test the class by creating four rectangles and combining these cumulatively to end up with a rectangle enclosing them all. Output the defining points of all the rectangles you create.Question#2:Define a class, mcmLength, to represent a length measured in meters, centimeters, and millimeters, each stored as integers. Include methods to add and subtract objects, to multiply and divide an object by an integer value, to calculate an area resulting from the product of two objects, and to compare objects. Include constructors that accept three arguments—meters, centimeters, and millimeters; one integer argument in millimeters; one double...

!! E! 4 2 You are in process of writing a class definition for the class Book. It has three data attributes: book title, book author, and book publisher. The data attributes should be private. In Python, write an initializer method that will be part of your class definition. The attributes will be initialized with parameters that are passed to the method from the main program. Note: You do not need to write the entire class definition, only the initializer method lili lilı

Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and...
