True or False? An initializer list can be used to instantiate an array object instead of using the new operator.

Computer Science Part 2: Client Program with ArrayList Create a second client program. This program will contain an ArrayList of StudentGrades objects. The program will perform the following tasks: Create an instance of an ArrayList that will store three StudentGrades objects. Each element in the ArrayList represents student grades for a test (assessment). This means that each StudentGrades object stored by the ArrayList element represents the grades achieved by students for a single test. Prompt the user for the number of students in the class. The prompt text is: Enter the number of students in the course: [Keyboard Input] Add three new StudentGrades objects to the ArrayList. The StudentGrades objects should be populated with random values from 0 to 100. Use the enhanced for loop to print each of the StudentGrades objects to the console. Print a line containing the following text: "LAST ELEMENT BEFORE REMOVE:". Print the value of the final element in the ArrayList under the heading....

17. Phone Book ArrayList Write a class named PhoneBookEntry that has fields for a person's name and phone number. The class should have a constructor and appropriate accessor and mutator methods. Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.

10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated...

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9

C++ c++ write a hangman game that randomly generates a word and prompts the user to guess one letter at a time, as shown in the sample run. Each letter in the word is displayed as asterisk. when the user makes a correct guess, the actual letter is then displayed. When the user finishes a word, display the number of misses and ask the user whether to continue to play with another word. Declare an array to store word as follow: Store 20 different words in a text file, read them into an array. Randomly pick a number 1..20 and use this word for the current round.
