For Chapter 6, section 6 of the book the image shows, I'm trying to solve a true or false question. I was wondering if you can help solve them and provide an explanation. Thank you Throws an exception if an element is added when it is "full". Supports addition of elements at the front of the list, the end of the list, and anywhere in between. Can hold objects of any Java class. Has only O(1) operations, including its constructor. Provides more than one Iterator.

Modify songVerse to play "The Name Game" (see OxfordDictionaries.com), by replacing "(Name)" with userName but without the first letter.Ex: If userName = "Kaitlin" and songVerse = "Banana-fana fo-f(Name)!", the program prints:Banana-fana fo-faitlin! Ex: If userName = "Kaitlin" and songVerse = "Fee fi mo-m(Name)", the program prints:Fee fi mo-maitlin Note: You may assume songVerse will always contain the substring "(Name)". *Please write this code in C++*
USE THE PROGRAM CODE BELOW TO CODE 1. COMMAND LINE ARGS CODE IN JAVA 1. Command Line Args Modify problem # 1 from Lab 8 to accept the values for the key as command line arguments. Your program may assume the arguments given at the command line are integers. If there are no arguments, print a message. If there is at least one argument, compute and print the average of the arguments. Note that you will need to use the parseInt method of the Integer class to extract integer values from the strings that are passed in. If any non-integer values are passed in, your program will produce an error, which is unavoidable at this point. Test your program in NetBeans using the data for problem # 1 Lab 8 as command line arguments. import java.util.Scanner;import java.text.NumberFormat; public class Quizzes{ //---------------------------------------------- // Read in the number of questions followed by // the key, then read in each student's answers // and calculate the number…

Please do in Java In many computer systems and networks,different users are granted different levels of access to different resources. In this case, you are given a int[] rights, indicating the privilege level of each user to use some system resource. You are also given a int minPermission, which is the minimum permission a user must have to use this resource. You are to return a String indicating which users can and cannot access this resource. Each character in the return value corresponds to the element of users with the same index. 'A' indicates the user is allowed access, while 'D' indicates the user is denied access. Constraints users will contain between 0 and 50 elements, inclusive. Each element of users will be between 0 and 100, inclusive. minPermission will be between 0 and 100, inclusive. Examples a) {0,1,2,3,4,5} 2 Returns: "DDAAAA" Here, the first two users don't have sufficient privileges, but the remainder do. b) {5,3,2,10,0} 20 Returns: "DDDDD"…
